Gender parity in neurosurgery residencies: an analysis.

OBJECTIVE: The number of women graduating from United States medical schools has reached parity with that of men. However, persistent inequalities and barriers have slowed the pace toward equity in application and representation in neurosurgery residency despite initiatives to increase female representation. The objective of the present study was to assess the advancement of gender parity within neurosurgery residency programs. Additionally, the study aimed to analyze the pipeline dynamics by investigating the effects of attrition on women in neurosurgery, as well as exploring the patterns of female applications to neurosurgery residency programs versus other surgical specialties. METHODS: Data on the number of active female neurosurgery residents and female applicants to neurosurgery were collected from the Accreditation Council for Graduate Medical Education Data Resource Book from 2007 to 2021 and Electronic Residency Application Service from 2014 to 2022. Linear regression analysis was used to predict the percent of active female residents based on academic year (AY). A Pearson chi-square test was used to determine the odds of a female applying to neurosurgery. RESULTS: The percent of active female residents in neurosurgery increased from 11.0% in 2007 to 21.8% in 2021. Bivariate linear regression analysis using AY as a predictor of the percent of active females showed a statistically significant correlation. On average, the percent of active female residents increased by 0.65% per year. If trends persist, parity for females in neurosurgery will not be reached until 2069. Linear regression analysis of the overall rate of attrition in neurosurgery as a predictor of the percent of active female residents revealed that for every 1% increase in the rate of attrition, the percent of active female residents decreased by 2.91% (p = 0.001). The percent of female applicants to neurosurgery increased from 19.6% in 2014 to 29.8% in 2022 (p = 0.009), yet the odds of a female applying to neurosurgery remain low. CONCLUSIONS: Neurosurgery continues to struggle with the recruitment of female medical students even as parity has been reached for female medical school matriculants. Greater effort is needed to recruit and retain female applicants to neurosurgery, including increased transparency in match and attrition metrics.

Intracranial tuberculoma: a rare complication of extrapulmonary tuberculosis. Illustrative case.

BACKGROUND: Intracranial tuberculomas are rare entities commonly seen only in low- to middle-income countries where tuberculosis remains endemic. Furthermore, following adequate treatment, the development of intracranial spread is uncommon in the absence of immunosuppression. OBSERVATIONS: A 22-year-old man with no history of immunosuppression presented with new-onset seizures in the setting of miliary tuberculosis status post 9 months of antitubercular therapy. Following a 2-month period of remission, he presented with new-onset tonic-clonic seizures. Magnetic resonance imaging demonstrated interval development of a mass concerning for an intracranial tuberculoma. After resection, pathological analysis of the mass revealed caseating granulomas within the multinodular lesion, consistent with intracranial tuberculoma. The patient was discharged after the reinitiation of antitubercular medications along with a steroid taper. LESSONS: To the best of the authors' knowledge, this case represents the first instance of intracranial tuberculoma occurring after the initial resolution of a systemic tuberculosis infection. The importance of retaining a high level of suspicion when evaluating these patients for seizure etiology is crucial because symptoms are rapidly responsive to resection of intracranial tuberculoma masses. Furthermore, it is imperative for surgeons to recognize the isolation steps necessary when managing these patients within the operating theater and inpatient settings.

Significant brainstem dysfunction in neonates with myelomeningoceles: a comparison of prenatal versus postnatal closure.

OBJECTIVE: The purpose of this study was to compare the incidence of significant brainstem dysfunction (SBD) in neonates with myelomeningocele who have been treated with prenatal versus postnatal closure at a single institution. METHODS: The records and imaging of all children undergoing either prenatal (n = 27) or postnatal (n = 60) closure of myelomeningocele at the authors' institution from December 2014 through May 2021 were reviewed. SBD, fetal ventricular size, gestational age at fetal imaging and delivery, postnatal ventricular size, need for and type of hydrocephalus treatment, spinal neurological level at birth, anatomical Chiari severity, death, and prenatal or postnatal repair were factors recorded. SBD was defined by need for airway surgery or gastrostomy tube, or endotracheal intubation because of apnea, aspiration, or airway control problems. Comparisons between prenatal and postnatal cohorts and between the cohorts with and without SBD were performed. RESULTS: SBD occurred in 25% and 0% of neonates who underwent postnatal and prenatal closure, respectively. There were no differences in fetal ventricular size or spinal neurological level between the prenatal and postnatal cohorts or between those with or without SBD. Anatomical severity of the Chiari malformation after birth was worse in the postnatal cohort. Hydrocephalus treatment was required in 70% and 33% of infants who underwent postnatal and prenatal closure, respectively. All three deaths were in the postnatal group from SBD. CONCLUSIONS: Prenatal closure of myelomeningocele is associated with a significant reduction in SBD.

Fulminant non-infectious peri-electrode edema after deep brain stimulation system implantation in a pediatric patient.

Non-infectious peri-electrode edema is a rare complication after implantation of a deep brain stimulation (DBS) electrode. DBS is frequently used in the management of movement disorders with increasing interest surrounding its value in more rare disorders associated with movement abnormalities. This is the report of a 10-year-old male with Cockayne syndrome who acutely developed symptomatic non-infectious, non-hemorrhagic peri-electrode edema 18 days postoperatively from implantation of a DBS system targeting the bilateral globus pallidus internus. CT head confirmed extensive vasogenic edema along the entire length of the left electrode, and infectious workup was negative. The patient required admission to the pediatric intensive care unit for management utilizing steroid, hypertonic, and hyperosmolar therapy due to the amount of mass effect. Symptoms reduced over a 7-day hospital stay and were completely resolved at 1 month without removal of the DBS system. Management of this rare entity remains controversial and often involves the use of steroids and anti-epileptic prophylaxis. This represents the first case of non-infectious peri-electrode edema reported in a pediatric patient and is especially notable for its fulminant nature.

Estimating the prevalence of neurosurgical interventions in adults with spina bifida using the Health Facts data set: implications for transition planning and the development of adult clinics.

OBJECTIVE: As the care of patients with spina bifida continues to evolve, life expectancy is increasing, leading to a critical need for transition planning from pediatric-based to adult-based care. The burden of neurosurgical care for adults with spina bifida remains unknown. In this study, the authors sought to use a large national data set to estimate the prevalence of neurosurgical interventions in adults with spina bifida. METHODS: This study utilized Health Facts, which is a de-identified proprietary data set abstracted from all Cerner electronic health records. It includes 69 million unique patients with > 500 million encounters in 580 centers. Validation, technical exclusions, and data filters were applied to obtain an appropriate cohort of patients. The ICD-9 and ICD-10 codes for all types of spinal dysraphism, as well as the Current Procedural Terminology (CPT) codes for hydrocephalus procedures, spinal cord untethering, and Chiari decompression, were queried and records were retrieved. Demographic variables along with differences in age groups and temporal trends were analyzed. RESULTS: Overall, 24,764 unique patients with ≥ 1 encounter with a spinal dysraphism diagnosis between 2000 and 2017 were identified. The pediatric cohort included 11,123 patients with 60,027 separate encounters, and the adult cohort included 13,641 patients with 41,618 separate encounters. The proportion of females was higher in the adult (62.9%) than in the pediatric (51.4%) cohort. Annual encounters were stable from 2 to 18 years of age, but then decreased by approximately half with a precipitous drop after age 21 years. The sex distribution of adults and children who underwent procedures was similar (54.6% female adults vs 52.4% female children). Surgical interventions in adults were common. Between 2013 and 2017, there were 4913 procedures for hydrocephalus, with 2435 (49.6%) adult patients. Similarly, 273 (33.3%) of the 819 tethered cord procedures were performed in adults, as were 307 (32.9%) of 933 Chiari decompressions. CONCLUSIONS: The Health Facts database offered another option for studying care delivery and utilization in patients aging with spina bifida. The median age of this population has now reached early adulthood, and a significant number of neurosurgical procedures were performed in adults. An abrupt drop in the rate of encounters occurred at 21 years of age, possibly reflecting transition issues such as access-to-care problems and lack of coordinated care.

Ventricular size measurement methods in fetuses considered for prenatal closure of myelomeningocele.

OBJECTIVE: Prenatal closure of myelomeningocele is associated with a reduced rate of hydrocephalus treatment. This need for hydrocephalus treatment is positively correlated with fetal ventricular width. When ventricular width is 15 mm or greater, the benefits of prenatal closure, as a method to decrease hydrocephalus treatment, are reduced. Thus, fetal ventricular size is an important factor when counseling families who are considering intrauterine surgery with mitigation of hydrocephalus as the primary goal. This study sought to determine whether imaging modality (ultrasound [US] vs MRI) and interobserver variability were factors in any ventricular size disparity seen on imaging studies. METHODS: The imaging studies of 15 consecutive fetuses who underwent prenatal myelomeningocele repair at Children's Mercy Fetal Health Center, Kansas City, Missouri, were reviewed. All fetuses were imaged with US and fetal MRI; on average (range), procedures were performed 3.8 (0-20) days apart. Three comparisons were performed to analyze interobserver and intermodality variability in ventricular width measurements: 1) retrospective comparison of dictated ventricular widths measured with MRI and US by pediatric radiologists (PRs) and maternal-fetal medicine specialists (MFMs), respectively; 2) blinded measurements obtained with US by PRs versus initial US-based measurements by MFMs, and blinded measurements obtained with MRI by PRs versus initial MRI-based measurements by PRs; and 3) blinded measurements obtained with MRI by PRs versus those obtained with US. RESULTS: Retrospective comparison showed that measurements with MRI by PRs were on average 2.06 mm (95% CI 1.43-2.69, p < 0.001) larger than measurements with US by MFMs. Blinded measurements with US by PRs were on average larger than dictated measurements obtained with US by MFMs, but by only 0.6 mm (95% CI 0.31-0.84, p < 0.001). When PRs measured ventricular size in a blinded fashion with both US and MRI, the mean width determined with MRI was significantly larger by 2.0 mm (95% CI 1.26-2.67, p < 0.0001). CONCLUSIONS: The ventricular width of these fetuses was larger when measured with MRI than US by an amount that could impact recommendations for fetal surgery. Every center involved in counseling families about the risks and benefits of fetal intervention for spina bifida needs to be aware of these possible imaging-based disparities.

Four-level Anterior Cervical Discectomy and Fusions: Results Following Multilevel Cervical Fusion With a Minimum 1-Year Follow-up.

STUDY DESIGN: A retrospective review of prospectively collected case series. OBJECTIVE: This is a retrospective review of prospectively collected data regarding the clinical outcomes, complications, and fusion rates of patients who underwent a 4-level (C3-C7) anterior cervical discectomy and fusion (ACDF). SUMMARY OF BACKGROUND: The use of multilevel ACDF for cervical spondylosis has been controversial. The literature regarding fusion rates and outcomes have been variable. This study intends to evaluate the outcomes following multilevel ACDF in a large cohort of patients. CLINICAL MATERIALS AND METHODS: Between 1994 and 2011, 60 patients underwent a 4-level ACDF by a single surgeon. All patients were followed for a minimum of 12 months, and outcome measures included neurological findings, presence or absence of radiographic fusion, and complication rates. All patients had radiographic documentation of spinal cord stenosis at 4 consecutive cervical levels as well as myelopathy and/or radiculopathy symptoms. RESULTS: Forty-eight patients underwent a single anterior procedure, only 5 patients underwent concurrent anterior and posterior fusion, and 7 patients required a second posterior surgery due to new-onset or residual symptoms or hardware complications after undergoing ACDF. Patients most commonly presented with paresthesias and were diagnosed with cervical stenosis. Overall, 18.3% reported early postoperative dysphagia; however, only 2 patients continued to have mild dysphagia symptoms on long-term follow-up. Other complications included hardware failure (11), residual neck pain (7), residual paresthesias (6), new-onset weakness (3), neck hematoma (1), cellulitis (1), and C5 radiculopathy (1). Overall, 88.3% of patients reported improvement in initial symptoms. Nurick scores were significantly lower following 4-level ACDF. The radiographic fusion rate for all levels was 95%. No patients required reoperation for pseudarthrosis. CONCLUSION: In appropriate patients, 4-level ACDF is a safe, efficacious method for treating multilevel cervical spinal cord compression, with acceptable complication rates and the ability to achieve neurological improvement and high fusion rates.

Intrathoracic migration of ventriculo-peritoneal shunt via Morgagni hernia.

We present the case of a 5-month-old patient presenting with pleural migration of ventriculo-peritoneal shunt catheter who returned 2 months later with respiratory distress. Ultimately, the diagnosis of a Morgagni hernia was made. This diagnosis, though rare, should be entertained in certain clinical settings.

The role of imaging for the management of newly diagnosed glioblastoma in adults: a systematic review and evidence-based clinical practice guideline update.

TARGET POPULATION: These recommendations apply to adults with a newly diagnosed lesion with a suspected or histopathologically proven glioblastoma (GBM). QUESTION: What are the optimal imaging techniques to be used in the management of a suspected glioblastoma (GBM), specifically: which imaging sequences are critical for most accurately identifying or diagnosing a GBM and distinguishing this tumor from other tumor types? RECOMMENDATIONS: Critical Imaging for the Identification and Diagnosis of Glioblastoma Level II: In patients with a suspected GBM, it is recommended that the minimum magnetic resonance imaging (MRI) exam should be an anatomic exam with both T2 weighted, FLAIR and pre- and post-gadolinium contrast enhanced T1 weighted imaging. The addition of diffusion and perfusion weighted MR imaging can assist in the assessment of suspected GBM for the purposes of distinguishing GBM from other tumor types. Computed tomography (CT) can provide additional information regarding calcification or hemorrhage and also can be useful for subjects who are unable to undergo MR imaging. At a minimum, these anatomic sequences can help identify a lesion as well as its location, and potential for surgical intervention. Improvement of diagnostic specificity with the addition of non-anatomic (physiologic imaging) to anatomic imaging Level II: One blinded prospective study and a significant number of case series support the addition of diffusion and perfusion weighted MR imaging in the assessment of suspected GBM, for the purposes of distinguishing GBM from other tumor types (e.g., primary CNS lymphoma or metastases). Level III: It is suggested that magnetic resonance spectroscopy (MRS) and nuclear medicine imaging (PET 18F-FDG and 11C-MET) be used to provide additional support for the diagnosis of GBM.

International electives in neurological surgery training: a survey of program directors from Accreditation Council for Graduate Medical Education-approved neurological surgery programs.

OBJECTIVE: The burden of neurosurgical disease in low- and middle-income countries (LMICs) has emerged as a significant factor in global health. Additionally, calls have been growing for first-world neurosurgeons to find ways to help address the international need. Allowing residents to pursue international elective opportunities in LMICs can help alleviate the burden while also providing unique educational opportunities. However, pursuing international work while in residency requires overcoming significant logistical and regulatory barriers. To better understand the general perspectives, perceived barriers, and current availability of international rotations, a survey was sent out to program directors at Accreditation Council for Graduate Medical Education (ACGME)-approved residencies. METHODS: An anonymous survey was sent to all program directors at ACGME-approved residencies. The survey included branch points designed to separate programs into program directors with an existing international rotation, those interested in starting an international rotation, and those not interested in starting an international rotation. All participants were asked about the perceived value of international training and whether residents should be encouraged to train internationally on a 5-point Likert scale. The survey ended with open-response fields, encouraging thoughts on international rotations and overcoming barriers. RESULTS: Forty-four percent of recipients (50/113) responded; of the 50 programs, 13 had an established international elective. Of programs without a rotation, 54% (20/37) noted that they were interested in starting an international elective. Key barriers to starting international training included funding, the Residency Review Committee approval process, call conflicts, and the establishment of international partners. Perceived learning opportunities included cultural awareness, unique pathology, ingenuity, physical examination skills, and diagnosis skills. The majority of respondents thought that international rotations were valuable (74%, 37/50) and that residents should be encouraged to pursue international educational opportunities (70%, 35/50). Program directors who maintained an existing international rotation or were interested in starting an international elective were more likely to perceive international rotations as valuable. CONCLUSIONS: Recent calls from The Lancet Commission on Global Surgery for increased surgical interventions in the developing world have been expanded by neurosurgical leadership to include neurosurgical diseases. Resident involvement in international electives represents an opportunity to increase treatment of neurosurgical disease in LMICs and develop the next generation of international neurosurgeons. To increase opportunities for residents at international sites, attention should be focused on overcoming the practical and regulatory barriers at a local and national level.

Current US neurosurgical resident involvement, interest, and barriers in global neurosurgery.

OBJECTIVE: It is estimated that nearly 47 million preventable deaths occur annually due the current worldwide deficit in surgical care; subsequently, the World Health Organization resolved unanimously to endorse a decree to address this deficit. Neurosurgeons from industrialized nations can help address the needs of underserved regions. Exposure during training is critical for young neurosurgeons to gain experience in international work and to cultivate career-long interest. Here, the authors explore the opinions of current residents and interest in global neurosurgery as well as the current state of international involvement, opportunities, and barriers in North American residency training. METHODS: An internet-based questionnaire was developed using the authors' university's REDCap database and distributed to neurosurgical residents from US ACGME (Accreditation Council for Graduate Medical Education)-approved programs. Questions focused on the resident's program's involvement and logistics regarding international rotations and the resident's interest level in pursuing these opportunities. RESULTS: A 15% response rate was obtained from a broad range of training locations. Twenty-nine percent of respondents reported that their residency program offered elective training opportunities in developing countries, and 7.6% reported having participated in these programs. This cohort unanimously felt that the international rotation was a beneficial experience and agreed that they would do it again. Of those who had not participated, 81.3% reported interest or strong interest in international rotations. CONCLUSIONS: The authors' results indicate that, despite a high level of desire for involvement in international rotations, there is limited opportunity for residents to become involved. Barriers such as funding and rotation approval were recognized. It is the authors' hope that governing organizations and residency programs will work to break down these barriers and help establish rotations for trainees to learn abroad and begin to join the cause of meeting global surgical needs. To meet overarching international neurosurgical needs, neurosurgeons of the future must be trained in global neurosurgery.

A rare case of a pediatric white epidermoid cyst.

White epidermoid cysts are a rare entity that present with atypical signal characteristics on MRI in comparison to typical epidermoid cysts. This can mislead a practitioner when trying to formulate a differential diagnosis based on imaging. We present the case of 15-year-old girl who presented with a pontine-medullar junction mass. This mass did not follow typical signal characteristics for known lesions. The mass was ultimately found to be an epidermoid cyst based on pathology findings. This lesion has rarely been reported in pediatric patients (J Pediatr Neurosci 9(1):52-54, 2014; Singap Med J 53(8):179-181, 2012). Here we present a rare case of an intracranial white epidermoid in a pediatric patient (Neurol India 62(5):577-579, 2014; Singap Med J 53(8):179-181, 2012; Am J Neuroradiol 19:1111-1112, 1998).

Coxiella burnetii infection of the spine requiring neurosurgical intervention.

BACKGROUND: Infections from Coxiella burnetii, resulting in what is known as Q fever, are relatively rare and difficult to diagnose. Very few reports of spinal infection from C. burnetii have been reported rarely have these cases required surgical intervention. CASE DESCRIPTION: We report a patient with the previous vascular surgery and Q fever spinal osteomyelitis. Previously reported cases with spinal involvement have described initial infection of vascular grafts in proximity to the spine. Literature on spinal infection from C. burnetii reports only one case that required surgical intervention of the spine. We report a patient with L5-S1 diskitis who required surgical intervention and subsequent percutaneous drainage. CONCLUSION: Spinal infections from C. burnetii are rare; however, in the setting of a patient with osteodiscitis with negative cultures as well as a history of significant vascular disease with stents, the diagnosis of Q fever should be entertained. Operative and interventional procedures should also be considered in these patients to help alleviate pain and maintain neurologic function.

Intracranial subdural empyemas and epidural abscesses in children

OBJECTIVE: The authors conducted a retrospective analysis of a consecutive series of children with intracranial subdural empyemas (SEs) and epidural abscesses (EAs) to highlight the important clinical difference between these two entities. They describe the delays and pitfalls in achieving accurate diagnoses and make treatment recommendations based on clinical and imaging findings. METHODS: They reviewed their experience with children who had presented with intracranial SE and/or EA in the period from January 2013 to May 2018. They recorded presenting complaint, date of presentation, age, neurological examination findings, time from presentation to diagnosis, any errors in initial image interpretation, timing from diagnosis to surgical intervention, type of surgical intervention, neurological outcome, and microbiology data. They aimed to assess possible causes of any delay in diagnosis or surgical intervention. RESULTS: Sixteen children with SE and/or EA had undergone evaluation by the authors' neurosurgical service since 2013. Children with SE (n = 14) presented with unmistakable evidence of CNS involvement with only one exception. Children with EA alone (n = 2) had no evidence of CNS dysfunction. All children older than 1 year of age had sinusitis. The time from initial presentation to a physician to diagnosis ranged from 0 to 21 days with a mean and median of 4.5 and 6 days, respectively. The time from diagnosis to neurosurgical intervention ranged from 0 to 14 days with a mean and median of 3 and 1 day, respectively. Delay in treatment was due to misinterpretation of images, a failure to perform timely imaging, progression on imaging as an indication for surgical intervention, or the managing clinician's preference. Among the 14 cases with SE, initial imaging studies in 6 were not interpreted as showing SE. Four SE collections were dictated as epidural even on MRI. The only fatality was associated with no surgical intervention. Endoscopic sinus surgery was not associated with reducing the need for repeat craniotomy. CONCLUSIONS: Regardless of the initial imaging interpretation, any child presenting with focal neurological deficit or seizures and sinusitis should be assumed to have an SE or meningitis, and a careful review of high-resolution imaging, ideally MRI with contrast, should be performed. If an extraaxial collection is identified, surgical drainage should be performed expeditiously. Neurosurgical involvement and evaluation are imperative to achieve timely diagnoses and to guide management in these critically ill children. ABBREVIATIONS: EA = epidural abscess; SE = subdural empyema.

The Impact of Regulation on Resident International Experiences: A Multispecialty Review of Current ACGME and RRC Standards for International Electives.

OBJECTIVE: Partnerships between industrialized and nonindustrialized institutions have accelerated the growth of surgery and surgical subspecialties in the developing world. The results of these partnerships include qualitive and quantitative clinical benefits as well as unique opportunities for the development of resident clinical and surgical skills. Surveys demonstrate surgical residents have a strong interest in international humanitarian work. Ultimately, the opportunities for residents to participate in international work as a program elective are subject to the regulations of the Accreditation Council of Graduate Medical Education (ACGME) and the Residency Review Committees (RRC) that govern residency accreditation. The regulations from accreditation bodies serve to ensure resident safety and educational value; however, excessive regulation can be a major hurdle to programs initiating international electives. Though the regulations are publicly available there is no comparison of various subspecialty standards in the literature. Nor is there a review of how standards affect resident education and safety or the ability for individual residencies to initiate international electives. METHODS: The regulations as defined by the ACGME and RRC of 7 surgical specialties (general, plastics, neurological, otolaryngology, ophthalmology, orthopedics, and urology) were reviewed from the available data on the ACGME website. RESULTS: The regulations demonstrate a great deal of diversity in how the specialties regulate international work. On one end of spectrum, 2 programs have robust guidelines and an approval process that ultimately allows residents to claim credit for cases performed internationally. On the other end, the regulations for some programs make little mention of international rotations other than to deny that cases be counted for credit. CONCLUSIONS: ACGME regulations have a strong effect on resident experiences while training internationally. Ideally, regulations should ensure resident safety and education without being overly cumbersome and preventing smaller programs from developing international electives. This would allow more residents access to the educational benefits available through meaningful international electives. Beyond the educational benefits, resident participation in international training creates a foundation for continued international work throughout their career. This could, in turn, increase the number of surgeons willing to travel internationally and bolster the development and consistency of international humanitarian e`fforts.

Perineal pain secondary to tethered cord syndrome: retrospective review of single institution experience.

OBJECT: Tethered cord syndrome (TCS) encompasses a spectrum of neurological dysfunction related to excessive tension on the distal spinal cord resulting in anatomic deformation and metabolic disturbance. Symptoms typically manifest as back/leg pain, neurogenic bladder dysfunction, constipation, sphincter abnormalities, and scoliosis. To date, among the least well-described symptoms of TCS is pain or hypersensitivity in the perineal region. The authors reviewed their experience with spinal cord detethering to identify and further characterize those who present with perineal pain or hypersensitivity. METHODS: Cases of spinal cord detethering at a single institution were retrospectively reviewed. Patients were initially identified by procedural codes. Cases were reviewed for presenting symptoms, specifically perineal pain or hypersensitivity. Magnetic resonance image (MRI) findings, clinical outcome, and length of follow-up were also noted. RESULTS: Of the 491 patients identified, seven patients (1.4%) were identified as having preoperative perineal pain or hypersensitivity. All of these patients had complete resolution of perineal pain/hypersensitivity at the time of last follow-up. Furthermore, five (71%) of these patients experienced resolution of all initial symptoms. CONCLUSION: Perineal pain or hypersensitivity can be an important symptom of spinal cord tethering. Spinal cord detethering may result in a good outcome and relief of perineal pain or hypersensitivity.
