Postoperative Spinal Subdural Extra-arachnoid Hygroma Because of Trauma: Resolution with Lumbar Puncture: A Case Report.

CASE: A 73-year-old woman, after spinal surgery, presented with symptomatic spinal subdural extra-arachnoid hygroma (SSEH) because of a fall on the third postoperative day. The hygroma was diagnosed by magnetic resonance imaging (MRI). Lumbar puncture was performed under local anesthesia, after which the leg pain disappeared immediately. MRI obtained immediately after puncture and 1 week later confirmed disappearance of the hygroma. CONCLUSION: Although dural transection is mentioned in most of the reports on treatment of symptomatic postoperative SSEH, we were able to treat this entity by epidural puncture. In the absence of paraplegia or cystorectal disturbance, puncture can be an effective and minimally invasive treatment option.

[Complicated course of the postoperative period with the development of epidural hygroma and intracranial hypotension after removal of cranio-orbital meningioma. Clinical case and literature review]. / Oslozhnennoe techenie posleoperatsionnogo perioda s razvitiem epidural'noi gigromy i vnutricherepnoi gipotenzii posle udaleniya kranioorbital'noi meningiomy.

Surgical removal of cranio-orbital meningiomas is an effective method of treating this pathology. Modern surgical techniques and technologies make it possible to perform operations with a low risk of complications. Lumbar drainage or repeated lumbar punctures are often used intraoperatively or in the early postoperative period to prevent nasal CSF leak; this rarely leads to the development of significant neurological symptoms. We present a case of the development of severe intracranial hypotension with the formation of a subdural hygroma in the early postoperative period after removal of a cranio-orbital meningioma in a 41-year-old patient. The operation was performed using an individual model and molds for simultaneous reconstruction of the bone defect with an implant made of polymethyl methacrylate. On the 1st and 2nd days after surgery, lumbar punctures were performed. From the 2nd day there was a progressive deterioration with the development of symptoms characteristic of intracranial hypotension. Computed tomography revealed an increasing displacement of the midline structures of the brain and an increasing volume of epidural fluid accumulation in the area of surgical intervention. Magnetic resonance imaging revealed characteristic signs of intracranial hypotension. Conservative treatment (bed rest, active hydration) had no effect. On the 6th day after surgery, an epidural blood patch procedure was performed and closed external drainage of the epidural hygroma was performed, and a rapid regression of neurological symptoms was noted. Our experience and literature data indicate that it is necessary to remember the possibility of developing clinically significant intracranial hypotension even after a single lumbar puncture. The formation of hygromas in the surgical area is characteristic of intracranial hypotension, but in most cases does not require additional surgical intervention and does not have a negative impact on the outcome of treatment. Conservative treatment of intracranial hypotension is the first choice and often sufficient. If there is no effect and the patient's condition worsens, it is necessary to perform an epidural blood patch procedure.

Retroperitoneal cystic lymphangioma in a cirrhotic patient: A case report and review of the literature.

Retroperitoneal cystic lymphangiomas (RCL) are rare benign tumors of the lymphatic system. They account for less than 1% of all lymphangiomas. Surgical resection is the recommended treatment option; however, obtaining a pre-operative diagnosis is often difficult and, in most cases, the final diagnosis is only possible following histological assessment of the surgical specimen. This report describes a case of RCL in a 58-year-old female cirrhotic patient who presented to our center with dull aching abdominal pain and distension. To our knowledge, this is the first case of a RCL in a cirrhotic patient reported in the literature.

Cerebral Microbleeds-Long-Term Outcome After Cerebrospinal Fluid Shunting in Idiopathic Normal Pressure Hydrocephalus.

BACKGROUND: Cerebral microbleeds (CMBs) are common in idiopathic normal pressure hydrocephalus (INPH) and have been suggested as radiological markers of a brain prone to bleeding. The presence of CMBs might be relevant when selecting patients for shunt surgery. OBJECTIVE: To evaluate whether CMBs increases long-term risk of hemorrhagic complications and mortality or affects outcomes after cerebrospinal fluid shunt surgery in a cohort of patients with INPH. METHODS: One hundred and forty nine shunted patients with INPH (mean age, 73 years) were investigated with MRI (T2* or susceptibility-weighted imaging sequences) preoperatively. CMBs were scored with the Microbleed Anatomic Rating Scale. Patients were observed for a mean of 6.5 years (range 2 weeks to 13 years) after surgery. Hemorrhagic events and death were noted. Improvement in gait was evaluated 3 to 6 months after surgery. RESULTS: At baseline, 74 patients (50%) had CMBs. During follow-up, 7 patients (5%) suffered a hemorrhagic stroke and 43 (29%) suffered a subdural hematoma/hygroma with a median time from surgery of 30.2 months (IQR 50). Overall, having CMBs was not associated with suffering a subdural hematoma/hygroma or hemorrhagic stroke during follow-up with 1 exception that an extensive degree of CMBs (≥50 CMB) was more common in patients suffering a hemorrhagic stroke ( P = .03). CMBs were associated with increased mortality ( P = .02, Kaplan-Meier, log-rank test). The presence of CMBs did not affect gait outcome ( P = .28). CONCLUSION: CMBs were associated with hemorrhagic stroke and mortality. CMBs do not seem to reduce the possibility of gait improvement after shunt surgery or contribute to the risk of hemorrhagic complications regarding subdural hematoma or hygroma.

Risk for hydrocephalus, hygroma, and tumor dissemination after ventricular opening during resection of supratentorial neoplasms in children.

PURPOSE: The possibility that ventricular opening generates postoperative complications after surgical tumor treatment often restricts the degree of tumor resection. This study aims to determine whether the ventricular opening is associated with more complications in surgeries for resectioning supratentorial intra-axial brain tumors in the pediatric population. METHODS: A retrospective review analysis was performed of patients treated at IOP/GRAACC between 2002 and 2020 under 19 years of age and underwent surgery for supratentorial intra-axial primary brain tumor resection. Data were collected from 43 patients. RESULTS: Glial tumor was more common than non-glial (65% vs. 35%, p = 0.09). The ventricular opening was not related to neoplastic spreads to the neuroaxis (6% vs. 0, p > 0.9) or leptomeningeal (3% vs. 0, p > 0.9). Of the patients whose ventricle was opened, 10% developed hydrocephalus requiring treatment, while none of the patients in the group without ventricular opening developed hydrocephalus (p = 0.5). There was also no statistical difference regarding ventriculitis. Postoperative subdural hygroma formation correlated with the ventricular opening (43% vs. 0, p = 0.003). The survival at 1, 5, and 10 years of cases with the ventricular opening was 93.2%, 89.7%, and 75.7%, respectively, while in cases without ventricular opening, it was 100%, 83%, and 83%, respectively, respectively, with no statistical difference between the mortality curves. CONCLUSION: Our study demonstrated that ventricular violation was not associated with the occurrence of significant complications. It was related to the formation of subdural hygroma, which did not require additional treatment.

Traumatic subdural hygroma and chronic subdural hematoma: A systematic review and meta-analysis.

Recently, a relationship between traumatic subdural hygroma (SDG) and chronic subdural hematoma (CSDH) has been proposed. However, the role of traumatic SDG in development of CSDH has not been well characterized. This systematic review aimed to estimate the rate of evolution of traumatic SDG to CSDH, and to identify risk factors associated with traumatic SDG evolution to CSDH. We searched MEDLINE, EMBASE, and Cochrane Library databases from inception to May 26, 2021, using the combination of the terms "subdural hygroma" and "chronic subdural hematoma." Using a random-effects model, we calculated a pooled estimate of rate of evolution of traumatic SDG to CSDH. In addition, we conducted a systematic review of studies of risk factors for traumatic SDG evolution to CSDH. Nineteen studies with 1,335 patients met the inclusion criteria for meta-analysis. The pooled estimate of evolution rate was 25.0 % (95 % CI, 19.3 %-30.7 %; I2 = 85.6 %), with significant heterogeneity among studies (P < 0.01). Age ≥ 60 years was associated independently with traumatic SDG evolution to CSDH, after adjustment for study design using multivariate meta-regression. Risk factors associated with evolution of traumatic SDG to CSDH were radiological characteristics such as thicker SDG and higher SDG CT value. The rate of traumatic SDGs evolution to CSDH is approximately 25 %. Patients aged 60 or older with traumatic SDGs are at increased risk of CSDH development. Thicker SDG and higher SDG CT value, are commonly reported risk factors for traumatic SDG evolution to CSDH. However, higher quality studies are needed.

Underestimating isolated bilateral hygroma as non-accidental head injury with dramatic consequences: a case presentation.

OBJECTIVE: Abusive head injury (AHI) in infancy is associated with significantly worse outcomes compared to accidental traumatic brain injury. The decision-making of the diagnosis of AHI is challenging especially if the clinical signs are not presenting as a multifactorial pattern. METHOD: We present a case of isolated bilateral hygroma in which this differential diagnosis of AHI was evaluated but primarily not seen as such leading subsequently to extensive secondary AHI with fatal brain injury. RESULTS: The case of an 8-week-old infant with apparently isolated bilateral hygroma without any external signs of abuse and no retinal hemorrhages was interpreted in causative correlation to the perinatal complex course of delivery. At a second readmission of the case, severe brain injury with bilateral cortical hypoxia, subarachnoid and subdural hemorrhages, and skull and extremity fractures led to severe disability of the affected infant. CONCLUSION: Any early suspicion of AHI with at least one factor possibly being associated with abusive trauma should be discussed in multidisciplinary team conferences to find the best strategy to protect the child. Beside clinical factors, social factors within the family household may additionally be evaluated to determine stress-related risk for traumatic child abuse. In general, prevention programs will be essential in future perspective.

Ultrasonography for Serial Monitoring and Management of Cerebrospinal Fluid Dynamic Disorders After Decompressive Craniectomy.

OBJECTIVE: Decompressive craniectomy (DC) is widely used to treat intracranial hypertension following severe head injury. However, impairments of cerebrospinal fluid (CSF) hydrodynamics such as hydrocephalus and subdural effusion are common complications that occur after DC. Therefore, monitoring of intracranial pressure is a staple of neurocritical care post-DC. The aim of this study was to assess the usefulness of transcranial duplex sonography (TDS) for serial monitoring and management of CSF disorders after DC. METHODS: A total of 100 patients who underwent DC between June 2016 and May 2019 were recruited for the study. Transcranial duplex sonography examinations were performed between 1-day and 1-year post-DC. Transcranial duplex sonography was mainly used for monitoring changes in ventricle size and morphology, and also to monitor intraventricular hemorrhage, hydrocephalus, intracranial hygromas, and ventricle changes during CSF release procedures. RESULTS: A total of 456 TDS examinations were performed on patients after DC. Of these, 402 were performed in the neuro-intensive care unit. Two patients had intraventricular hemorrhage and underwent TDS-guided external ventricular drainage. Twenty-nine patients were diagnosed with hydrocephalus. The results of TDS were consistent with those of cranial computed tomography. Three cases of ventriculoperitoneal shunt and 1 case of lumbar peritoneal shunt underwent valve pressure reset according to TDS, to obtain satisfactory ventricle size. Transcranial duplex sonography was used to monitor ventricle changes and control drainage volume during CSF release procedures, including 2 external ventricular drainage, 6 external lumbar drainage, and 10 lumbar punctures. Eighteen patients were detected with single or multiple intracranial effusions, including 16 subdural hygromas, 5 longitudinal fissure hygromas, and 6 brain cysts. CONCLUSIONS: Transcranial duplex sonography can efficiently help monitor changes in ventricle size and morphology and intracranial effusions. Due to its noninvasive nature, suitability for bedside application, real-time, and inexpensiveness, TDS can significantly replace cranial computed tomography and become part of the patient's daily inspection work after DC.

The Transformation of Intracranial Subdural Hygroma to Chronic Subdural Hematoma Following Endoscopic Spinal Surgery: A Case Report.

BACKGROUND: We present the case of an intracranial subdural hygroma resulting from intraoperatively undetected dural tear after unilateral biportal endoscopic (UBE) spine surgery for lumbar spinal stenosis. CASE DESCRIPTION: An 80-year-old woman presented with insidious onset, gradually progressing low back pain, and right leg pain of 1-year duration. The pain radiated to the right L4-L5 dermatomes. Neurogenic intermittent claudication was <300 m. Motor function was normal. Lumbar magnetic resonance imaging showed a lateral recess stenosis at the L3-L4 and L4-L5 levels. These lesions were operated on by the UBE decompression technique.No major complications were encountered during the operation. But soon we found out that there was an undiscovered dura tear. We placed the patient under close observation for 2 weeks. After 30 days, we confirmed that subdural hygroma had changed to chronic subdural hematoma. Conservative treatment was continued. On postoperative day 90), the condition was stable and the symptoms improved completely. CONCLUSIONS: We concluded that a spinal cerebrospinal fluid leakage can result in an intracranial subdural hygroma. Intracranial subdural hygromas and hematomas after lumbar spinal surgery should be cautiously assessed and treated.

Long-term outcome of fetus with ameliorated cystic hygroma.

OBJECTIVE: Cystic hygroma often ameliorates or disappears with pregnancy progression. Fetuses/neonates with amelioration, when without chromosomal or major structural abnormality, generally show a favorable outcome at birth. The present study was aimed to clarify the short/long-term outcomes of fetuses/neonates with the amelioration of cystic hygroma during pregnancy. MATERIAL AND METHODS: This was a retrospective observational study. We focused on fetuses with cystic hygroma managed in our institute between January 2006 and June 2019. The infants were followed by pediatricians (neonatologist, pediatric cardiologist, and pediatric neurologist) and pediatric outcomes were retrieved from the medical records up to 3 years old. RESULTS: One hundred and seven fetuses with cystic hygroma were included. Of the 107, cystic hygromas ameliorated in 31 fetuses (31/107: 29%). Of the 31, there were 26 livebirths. Half (n = 13) of the 26 fetuses had a good outcome, whereas the remaining half (n = 13) had abnormalities. Various abnormalities were detected in their infancies. A nuchal thickness (diameter of hygroma) of ≥5 mm was significantly correlated with abnormalities (P = 0.047). CONCLUSION: Physicians should pay attention to fetuses/neonates with ameliorated cystic hygroma. Of those, special attention should be paid to fetuses/neonates with a nuchal thickness at diagnosis ≥5 mm.

Factors associated with the development and outcome of hydrocephalus after decompressive craniectomy for traumatic brain injury.

Posttraumatic hydrocephalus (PTH) is common in patients undergoing decompressive craniectomy (DC) for traumatic brain injury (TBI), but the incidence, mechanisms, and risk factors have not been fully elucidated. This study aimed to determine the incidence of and the factors associated with PTH. We retrospectively reviewed patients who underwent DC for TBI at our institute between January 2014 and December 2018. We identified and compared the demographic, clinical, and radiological data, and 12-month functional outcome (as assessed by the Glasgow Outcome Scale [GOS]) between patients who developed PTH and those who did not. Logistic regression analyses were performed to identify risk factors for PTH. Additionally, the influence of PTH on unfavorable functional outcome was analyzed. PTH developed in 18 (18.95%) of the 95 patients who survived at 1 month after DC. A multivariate analysis indicated that postoperative intraventricular hemorrhage (odds ratio [OR] 4.493, P = 0.020), postoperative subdural hygroma (OR 4.074, P = 0.021), and postoperative hypothermia treatment (OR 9.705, P = 0.010) were significantly associated with PTH. The 12-month functional outcome significantly differed between the patients who developed PTH and those who did not (P = 0.049). Patients who developed PTH had significantly poorer 12-month functional outcomes than those who did not (P = 0.049). Another multivariate analysis indicated that subdural hemorrhage (OR 6.814, P = 0.031) and the presence of at least one dilated pupil before DC (OR 8.202, P = 0.000) were significantly associated with unfavorable functional outcomes (GOS grades 1-3). Although the influence of PTH (OR 5.122, P = 0.056) was not statistically significant in the multivariate analysis, it had a great impact on unfavorable functional outcomes. PTH considerably affects functional outcomes at 12 months after DC for TBI. Furthermore, postoperative imaging findings such as intraventricular hemorrhage and subdural hygroma can predict the development of PTH; therefore, careful observation is required during the follow-up period.

Cystic lymphangioma of the stomach with marked reactive changes: a rare cause of gastric outlet obstruction in adult.

Cystic lymphangiomas are benign lymphatic tumours which usually affect the paediatric population and are predominantly located in the head and neck region. Its occurrence during adulthood and an intra-abdominal location are both extremely uncommon. Clinically and radiologically, these lesions often mimic malignancy. Infrequently, these tumours can undergo degenerative and reactive changes obscuring the diagnostic features. We describe hereby an anecdote of cystic lymphangioma with marked reactive changes presenting with the features of gastric outlet obstruction in an adult patient.

Huge omental lymphangioma with haemorrhage in children: case report.

Omental cystic lymphangioma is a rare benign intraabdominal anomaly with uncertain etiology, predominantly occurring in children. Most cases of abdominal lymphangioma are asymptomatic. However, patients may occasionally present with acute abdomen because of an intestinal obstruction or peritonitis caused by infected cysts, hemorrhaging, and/or torsion. This report describes a case of omental cystic lymphangioma with acute intracystic haemorrhage. Ultrasonography and computed tomography (CT) scan confirmed the diagnosis. Complete excision of the cyst along without omentectomy done with no clinical or radiological evidence of recurrence till 17 months.

Pediatric syndromes with noncraniofacial anomalies impacting the airways.

Syndromes with noncraniofacial abnormalities can be a real challenge in terms of airway management. The key to success is effective preparation, presence of personnel with expertise in difficult pediatric airway management, regular training and familiarity with difficult intubation equipment, and teamwork. Considering that there are a very large number of syndromes, with variable phenotypic expression, the management strategy of every case will be dictated by the anatomical and functional airway as assessed on physical examination and subsidiary examinations before induction of anesthesia.

Role of Ultrasound in Emergency Front of Neck Access: A Case Report and Review of Literature.

Emergency front of neck access (eFONA) is a lifesaving procedure in a cannot intubate cannot oxygenate (CICO) situation. We report a case of a patient who presented to the emergency department (ED) in extremis with a difficult airway. A history of multiple neck surgeries and permanent tracheostomy from birth until the age of 17 years complicated his airway management. Altered neck anatomy led to failed intubation and oxygenation. EFONA was established with the use of rapid ultrasound imaging and using the scalpel-bougie-tube technique. We present a review of literature relating to the use of ultrasound during emergency airway management.

Fetal giant right cervical cyst causing severe tracheal compression: A case report.

RATIONALE: Fetal giant cervical cyst (FGCC) is a rare congenital anomaly. Sometimes FGCC may extend into the mediastinum, and result in severe tracheal compression, which is a life-threatening event at birth. PATIENT CONCERNS: We present a rare case of FGCC, which extended from the right neck into the superior mediastinum, and resulted in severe tracheal compression. DIAGNOSES: An FGCC was observed by ultrasonography and magnetic resonance imaging (MRI) at 27+4 weeks' gestation (WG). Fetal MRI at 35+1 WG showed that the FGCC was 3.3 × 8.2 × 7.5 cm and extended from the right neck into the superior mediastinum. Severe tracheal compression was observed and the inside diameter of the narrowest section of tracheostenosis appeared thread-like and measured only 0.1 cm. INTERVENTIONS: Cervical cyst reduction was performed prenatally under ultrasound guidance to alleviate the tracheal compression and maximize the chance of fetal survival 2 days before birth. At 36+3 WG, cesarean section was performed, and a female neonate was immediately delivered and intubated (3.5-mm tube) by an experienced anesthesiologist. Neonatal intralesional sclerotherapy and cystic component aspiration as guided by digital subtraction angiography were performed under general anesthesia. Anesthesia was maintained only with sevoflurane 3% in 2 L/min oxygen. Extubation was performed soon after surgery. OUTCOME: The neonate recovered uneventfully and was discharged 2 days postoperatively. After 140 days of follow-up, the neonate had recovered completely. LESSONS: If an FGCC is suspected by abdominal ultrasound, a fetal MRI is recommended to assess the severity of tracheal compression before birth, if feasible. An anesthesiologist should assess the risk of intubation failure at birth according to those results. If fetal severe tracheal compression is detected and it may result in inability of intubation at birth, prenatal cervical cyst reduction under ultrasound guidance may be effective for alleviating tracheal compression at birth, if feasible. This could maximize the chance of fetal survival. Improvement of fetal short- and long-term outcomes is important.
