Sciatica caused by spinal epidural abscess as the initial clinical presentation of colon cancer: a rare case report and review of literature.

BACKGROUND: Colorectal cancer is one of the most frequently diagnosed forms of cancer, and it is associated with several common symptoms and signs such as rectal bleeding, altered bowel habits, abdominal pain, anemia, and unintentional weight loss. Sciatica, a debilitating condition in which the patient experiences paresthesia and pain in the dermatome of associated lumbosacral nerve roots or sciatic nerve distribution, is not considered one of these. Here we present a case of colorectal cancer manifesting symptoms of sciatica alone. CASE PRESENTATION: A 68-year-old male presented with progressive lower back pain radiating to his left thigh and calf over L5/S1 dermatome. Sciatica was suspected and initially underwent conservative treatment with analgesics. However, the symptoms progressed and MRI revealed an epidural abscess surprisingly. Surgical debridement was performed and pus culture isolated Streptococcus gallolyticus. Based on the strong association of S. gallolyticus with colorectal cancer, the presence of this pathogen prompted further tumor evaluation, even in the absence of the typical symptoms and signs. This investigation ultimately leads to the diagnosis of sigmoid adenocarcinoma. CONCLUSIONS: Although rare, sciatica caused by S. gallolyticus infection of the spinal epidural space may serve as the initial presentation of colorectal cancer. Physicians should be aware of the strong association between S. gallolyticus and colorectal cancer. Based on what we currently know about the condition; a thorough systematic assessment of occult neoplasia for patients with S. gallolyticus infection is recommended.

Surgical Treatment of Brucellar Cervical Epidural Abscess.

OBJECTIVES: Brucellar cervical epidural abscess (CEA) is a rare condition with potentially permanent neurological damage if left untreated. This study aims to define the clinical presentation of brucellar CEA and evaluate the outcome of surgical treatment, specifically decompression and fusion surgery. The findings will contribute to understanding whether all patients with brucellar CEA could benefit from this surgical intervention. METHODS: A retrospective study on brucellar spondylitis was conducted at the First Hospital of Jilin University from August 2018 to August 2022. During this period, a total of 37 patients were diagnosed with brucellar spondylitis at the hospital. Out of the 37 cases, six patients (16.2%) were confirmed to have CEA through cervical magnetic resonance imaging examination and serology test results.. RESULTS: Six patients were diagnosed with brucellar CEA (16.2%), of whom 5 successfully underwent anterior cervical decompression and fusion surgery. One patient had a large prevertebral abscess that could only be drained. In combination with effective antibiotic therapy, the clinical performance of the 5 patients who underwent surgery improved after the surgery. The remaining one patient required delayed surgery due to instability of the cervical spine. The follow-up period of all the 6 patients was 6 months. CONCLUSIONS: Brucellosis should be considered as a potential cause of CEA, especially in endemic areas. Timely detection and effective management of this condition are crucial in order to minimize the associated morbidity and mortality. For patients with detectable brucellar CEA, we recommend decompression and fusion surgery.

Treatment of Spinal Infections.

The treatment of spinal infections is not well defined, and a cursory review of the literature can lead to conflicting treatment strategies. To add to the complexity, infections can include primary infection of the spine, infection secondary to another primary source, and postoperative infections including epidural abscesses, discitis, osteomyelitis, paraspinal soft-tissue infections, or any combination. Furthermore, differing opinions often exist within the medical and surgical communities regarding the outcomes and effectiveness of varying treatment strategies. Given the paucity of defined treatment protocols and long-term follow-up, it is important to develop multidisciplinary treatment teams and treatment strategies. This, along with defined protocols for the treatment of varying infections, can provide the data needed for improved treatment of spinal infections.

Spinal fungal abscess mimicking as potts spine.

Spinal epidural abscess (SEA) is a rarest form of spinal infections and is characterized by the presence of pus in the space between the dura mater, and the osseoligamentous confines of the vertebral canal. This can cause spinal injury due to direct compression or local ischemia. The major etiology of SEA is bacterial and tuberculous in endemic regions. The incidence of fungal spinal abscess is relatively low and <5% of SEA is attributable to fungi. We, here, report a case of 77-year-old known patient of chronic renal disease on hemodialysis that presented with low-back pain for 15 days and was subsequently diagnosed with SEA by magnetic resonance imaging, and causative organism was identified as Candida by culture. The abscess was surgically drained after laminectomy. The patient improved with surgery and antifungal treatment.

Spinal Epidural Abscess and Strep Pharyngitis.

Spinal epidural abscesses (SEA) require prompt diagnosis to avoid devastating consequences. Here, we discuss the case of a healthy 20-year-old college student-with a recent diagnosis of strep pharyngitis-who presented with neck pain, fever, and a neurologic deficit-the most common symptoms of SEA. Magnetic resonance imaging revealed a T1-postcontrast, peripherally enhancing epidural collection from C3-T5 with associated cord compression and T3 osteomyelitis. The patient was treated with emergent skip hemilaminectomies for abscess evacuation. Surgical cultures grew Fusobacterium necrophorum, a highly unusual pathogen in SEA. It is an oral anaerobe that translocated through the mucosa in the setting of strep pharyngitis. We treated the patient with ceftriaxone for 6 weeks. The patient had a full neurologic recovery and remains without recurrence of infection 11 months postoperatively. Healthy patients without obvious risk factors may present with SEA, highlighting the need for atypical cases such as these to be brought to clinicians' attention.

Spinal epidural abscess as predicting factor for the necessity of early surgical intervention in patients with pyogenic spondylitis.

BACKGROUND: Pyogenic spondylitis is a condition with low incidence that can lead to neurological sequelae and even life-threatening conditions. While conservative methods, including antibiotics and bracing, are considered the first-line treatment option for pyogenic spondylitis, it is important to identify patients who require early surgical intervention to prevent progressive neurologic deficits or deterioration of the systemic condition. Surgical treatment should be considered in patients with progressive neurologic deficits or deteriorating systemic condition. However, currently, there is a lack of treatment guidelines, particularly with respect to whether surgical treatment is necessary for pyogenic spondylitis. This study aims to analyze the radiological epidural abscess on MRI and clinical factors to predict the need for early surgical intervention in patients with pyogenic spondylitis and provide comprehensive insight into the necessity of early surgical intervention in these patients. METHODS: This study retrospectively reviewed 47 patients with pyogenic spondylitis including spondylodiscitis, vertebral osteomyelitis, epidural abscess, and/or psoas abscess. All patients received plain radiographs, and a gadolinium-enhanced magnetic resonance imaging (MRI) scan. All patients have either tissue biopsies and/or blood cultures for the diagnosis of a pathogen. Demographic data, laboratory tests, and clinical predisposing factors including comorbidities and concurrent other infections were analyzed. RESULTS: We analyzed 47 patients, 25 of whom were female, with a mean age of 70,7 years. MRI revealed that 26 of 47 patients had epidural abscesses. The surgical group had a significantly higher incidence of epidural abscess than the non-surgical group (p = 0.001). In addition, both CRP and initial body temperature (BT) were substantially higher in the surgical group compared to the non-surgical group. There was no significant difference between the surgical group and the non-surgical group in terms of age, gender, comorbidities, and concurrent infectious disorders, as well as the number of affected segments and affected spine levels. However, the surgical group had lengthier hospital stays and received more antibiotics. CONCLUSION: The presence of an epidural abscess on MRI should be regarded crucial in the decision-making process for early surgical treatment in patients with pyogenic spondylitis in order to improve clinical outcomes.

Button-Hole Disco-Osteotomy Drainage-A Novel Approach for High-Risk Patients with Cervical Abscess.

Spinal epidural abscess (SEA) is a very serious infection of the central nervous system (CNS). It is of very low incidence with a peak age in the geriatric age group. Immunocompromised patients are more susceptible to SEA. It can present with significant neurological deficits, which can be permanent if not identified and treated promptly. In this case report, a 75-year-old immunocompromised patient presented with progressive spastic quadriparesis and septicemia. He was diagnosed with a case of cervical spinal epidural abscess with underlying cord compression. Anterior retropharyngeal approach and button-hole disco-osteotomy of C5-C6 was performed and the cervical SEA was drained, followed by antibiotic saline irrigation (cranially and caudally) was done, total duration of surgery was 70 min. At the time of discharge (7th postoperative day), the patient improved neurologically and sepsis had resolved.

Bilateral decompressive craniotomy complicated by postoperative mycoplasma hominis epidural empyema and meningitis: A case report.

RATIONALE: Postoperative intracranial mycoplasma hominis infection was a rare complication. Timely diagnosis was difficult due to its growth characteristics and nonspecific clinical symptoms. PATIENT CONCERNS: A 52-year-old man underwent bilateral decompressive craniotomy for severe traumatic brain injury. On the seventeenth day after surgery, the patient developed an unexplained high fever. Empirical anti-infective therapy was ineffective, and the fever persisted. In addition, viscous pus oozed from the head incision. Empiric therapy was still ineffective, the fever persisted, and the culture result was negative. The lumbar puncture pressure was 150 mmH2O and the cerebrospinal fluid white blood cell count was 3600 × 106/L, suggesting an intracranial infection. DIAGNOSES: Culture growth morphologically consistent with mycoplasma species was obtained from multiple specimens (scalp incision fluid and cerebrospinal fluid) and the identification of mycoplasma hominis was confirmed by 16S rDNA sequencing. INTERVENTION: Targeted anti-infective therapy (Minocycline), change of fresh wound dressing, and continued lumbar cerebrospinal fluid drainage. OUTCOME: At the 3-month follow-up, the patient was still in the rehabilitation department of the local hospital for treatment, but there were no symptoms of intracranial infection. LESSONS: Neurosurgeons should carefully examine postoperative incisions and be aware of the possibility of mycoplasma infection during clinical management.

Duration of neurological deficit and outcomes in the surgical treatment of spinal coccidioidomycosis.

OBJECTIVE: Vertebral osteomyelitis is a rare complication of coccidioidomycosis infection. Surgical intervention is indicated when there is failure of medical management or presence of neurological deficit, epidural abscess, or spinal instability. The relationship between timing of surgical intervention and recovery of neurological function has not been previously described. The purpose of this study was to investigate if the duration of neurological deficits at presentation affects neurological recovery after surgical intervention. METHODS: This was a retrospective study of all patients diagnosed with coccidioidomycosis involving the spine at a single tertiary care center between 2012 and 2021. Data collected included patient demographics, clinical presentation, radiographic information, and surgical intervention. The primary outcome was change in neurological examination after surgical intervention, quantified according to the American Spinal Injury Association Impairment Scale. The secondary outcome was the complication rate. Logistic regression was used to test if the duration of neurological deficits was associated with improvement in the neurological examination after surgery. RESULTS: Twenty-seven patients presented with spinal coccidioidomycosis between 2012 and 2021; 20 of these patients had vertebral involvement on spinal imaging with a median follow-up of 8.7 months (IQR 1.7-71.2 months). Of the 20 patients with vertebral involvement, 12 (60.0%) presented with a neurological deficit with a median duration of 20 days (range 1-61 days). Most patients presenting with neurological deficit (11/12, 91.7%) underwent surgical intervention. Nine (81.2%) of these 11 patients had an improved neurological examination after surgery and the other 2 had stable deficits. Seven patients had improved recovery sufficient to improve by 1 grade according to the AIS. The duration of neurological deficits on presentation was not significantly associated with neurological improvement after surgery (p = 0.49, Fisher's exact test). CONCLUSIONS: The duration of neurological deficits on presentation should not deter surgeons from operative intervention in cases of spinal coccidioidomycosis.

Changes in the epidemiology of pediatric sinogenic and otogenic intracranial infections during the COVID-19 pandemic: a single-institution study.

OBJECTIVE: Focal intracranial infections (epidural abscesses, subdural empyemas, and intraparenchymal abscesses) are uncommon complications of sinusitis and otitis media but can be associated with significant morbidity. Treatment typically requires neurosurgical and otolaryngological interventions in combination with antibiotic treatment. Historically, children have presented to the authors' pediatric referral center with sinusitis- or otitis media-related intracranial infections in low numbers. However, since the onset of the COVID-19 pandemic, the incidence of intracranial pyogenic complications has increased at this center. The objective of this study was to compare the epidemiology, severity, microbial causes, and management of pediatric sinusitis- and otitis-related intracranial infections in the periods before and during the COVID-19 pandemic. METHODS: All patients 21 years of age or younger who presented with an intracranial infection in the setting of sinusitis or otitis media and who underwent neurosurgical treatment at Connecticut Children's from January 2012 to December 2022 were retrospectively reviewed. Demographic, clinical, laboratory, and radiological data were systematically collated, and variables before and during COVID-19 were compared statistically. RESULTS: Overall, 18 patients were treated for sinusitis-related (n = 16) or otitis media-related (n = 2) intracranial infections during the study period. Ten patients (56%) presented from January 2012 to February 2020, none from March 2020 to June 2021, and 8 (44%) from July 2021 to December 2022. There were no significant demographic differences between the pre-COVID-19 and COVID-19 cohorts. The 10 patients in the pre-COVID-19 cohort underwent a total of 15 neurosurgical and 10 otolaryngological procedures, while the 8 patients in the COVID-19 cohort underwent a total of 12 neurosurgical and 10 otolaryngological procedures. Surgically obtained wound cultures yielded a variety of organisms; Streptococcus constellatus/S. anginosus/S. intermedius were more prevalent in the COVID-19 cohort (87.5% vs 0%, p < 0.001) as was Parvimonas micra (62.5% vs 0%, p = 0.007). CONCLUSIONS: At an institutional level, there has been an approximately threefold increase in cases of sinusitis- and otitis media-related intracranial infections during the COVID-19 pandemic. Multicenter studies are needed to confirm this observation and to investigate whether the mechanisms of infection are related directly to SARS-CoV-2, changes in the respiratory flora, or delayed care. The next steps will include expansion of this study to other pediatric centers throughout the United States and Canada.

Epidural Abscess After Injection Pharyngoplasty: A Case Report.

VPI occurs when the seal between the oral and nasal cavities does not doesn't close completely. One of the treatment options is an injection pharyngoplasty (IP). We are presenting a life threating -threatening case of epidural abscess after in- office injection pharyngoplasty IP. Laryngoscope, 133:3409-3411, 2023.

Mortality, complication risks, and clinical outcomes after surgical treatment of spinal epidural abscess: a comparative analysis of patients aged 18-64 years, 65-79 years, and ≥ 80 years, with a 3-year follow-up.

Spinal epidural abscess (SEA) with pyogenic vertebral osteomyelitis (PVO) is a rare illness with a steadily increasing incidence. However, comparative analyses of young and older patients with SEA are lacking. We aimed to compare the clinical course of patients aged 18-64 years, 65-79 years, and ≥ 80 years undergoing surgery for SEA. Clinical and imaging data were retrospectively collected from the institutional database between September 2005 and December 2021. Ninety-nine patients aged 18-64 years, 45 patients aged 65-79 years, and 32 patients ≥ 80 years were enrolled. Patients ≥ 80 years presented with a poorer baseline history (9.2 ± 2.4), as indicated by the CCI, than their younger counterparts (18-74 years: 4.8 ± 1.6;6.5 ± 2.5; p < 0.001). Patients aged 65-79 years and 80 years had a significantly longer length of stay. In-hospital mortality was significantly higher in those aged ≥ 80 years compared to their younger counterparts (≥ 80 years, n = 3, 9.4% vs. 18-64 years, n = 0, 0.0%; 65-79 years, n = 0, 0.0%; p < 0.001), while no differences in 90-day mortality or 30-day readmission were observed. After surgery, a significant decrease in C-reactive protein levels and leukocytes and amelioration of motor scores were observed in all the groups. Of note, older age (> 65 years), presence of comorbidities, and poor preoperative neurological condition were significant predictors of mortality. Surgical management led to significant improvements in laboratory and clinical parameters in all age groups. However, older patients are prone to multiple risks, requiring meticulous evaluation before surgery. Nevertheless, the risk profile of younger patients should not be underestimated. The study has the limitations of a retrospective design and small sample size. Larger randomized studies are warranted to establish the guidelines for the optimal management of patients from every age group and to identify the patients who can benefit from solely conservative management.

Emergency surgery for a patient with a thoracic spinal epidural abscess: a case report and literature review.

A man in his early 40s visited the Emergency Department because of no motor function in his lower limbs for 10 hours. Magnetic resonance imaging of his thoracic spine showed that the thoracic spinal canal (T2-T6) was occupied, and the thoracic spinal cord was compressed. In view of the severe symptoms, we quickly completed preoperative preparations and performed a thoracic laminectomy within 24 hours of paralysis of both lower limbs. Postoperatively, the patient underwent rehabilitation exercise. Four weeks later, the patient's lower limbs had full 5/5 strength. We reviewed the related literature to summarize the clinical guidelines with spinal surgeons. Timely diagnosis of thoracic spinal epidural abscess, early surgical treatment, and anti-infection management and rehabilitation exercise are essential for the full recovery of lower limb muscle strength.

Review of management practices of sinogenic intracranial abscesses in children.

OBJECTIVE: This study aimed to evaluate the management practices and outcomes in children with sinogenic intracranial suppuration. METHOD: This was a retrospective cohort study in a single paediatric tertiary unit that included patients younger than 18 years with radiologically confirmed intracranial abscess, including subdural empyema and epidural or intraparenchymal abscess secondary to sinusitis. Main outcomes studied were rate of return to the operating theatre, length of hospital stay, death in less than 90 days and neurological disability at 6 months. RESULTS: A cohort of 39 consecutive patients presenting between 2000 and 2020 were eligible for inclusion. Subdural empyema was the most common intracranial complication followed by extradural abscess and intraparenchymal abscess. Mean length of hospital stay was 42 days. Sixteen patients were managed with combined ENT and neurosurgical interventions, 15 patients underwent ENT procedures alone and 4 patients had only neurosurgical drainage. Four patients initially underwent non-operative management. The rates of return to the operating theatre, neurological deficits and 90-day mortality were 19, 9 and 3, respectively, and were comparable across the 4 treatment arms. In the univariate logistic regression, only the size of an intracranial abscess was found be associated with an increased likelihood of return to the operating theatre, whereas combined ENT and neurosurgical intervention did not result in improved outcomes. CONCLUSION: Sinogenic intracranial abscesses are associated with significant morbidity and mortality. The size of an intracranial abscess has a strong association with a need for a revision surgery.

Neisseria gonorrhoeae cervical spine epidural abscess requiring spinal decompression and instrumented fusion.

Disseminated gonococcal infection (DGI) is an uncommon complication of Neisseria gonorrhoeae infection, and typically presents with either a triad of tenosynovitis, dermatitis and polyarthralgia, or with extra-axial large joint septic arthritis. Spinal epidural abscess is a rare manifestation of DGI, with only a few previously reported cases, none of which required placement of metalware into the infected space. Here we report a severe case of isolated N. gonorrhoeae cervical spine epidural abscess necessitating surgical source control (C7/T1 laminectomy and debridement) and metalware placement (C6-T2 posterior instrumented fusion). The case was successfully managed by a combination of surgical intervention followed by six weeks of predominantly oral, targeted antimicrobial therapy.
