RESUMO

RATIONALE: Spinal involvement in adult Langerhans cell histiocytosis (LCH) is rare, and epidural involvement is unusual. LCH is mostly indistinguishable from other spinal lesions such as infection, lymphoma, and metastasis. So, it could be easily misdiagnosed without suspicion. PATIENT CONCERNS: We report a case of a 33-year-old man who complained of gait disturbance with weakness in both legs and severe back pain. DIAGNOSES: A continuous enhancing epidural lesion with cord compression from the T7 to L1 level was detected in magnetic resonance imaging. Laboratory analysis indicated the possibility of spinal infectious disease. We assumed that the lesion could be tuberculous spondylitis. INTERVENTIONS AND OUTCOMES: The patient underwent posterior laminectomy with marginal excision of the epidural mass to relieve cord compression. Pathological examination confirmed the diagnosis of LCH. The 12-month follow-up evaluation revealed that the patient was neurologically intact and had no gait disturbance. LESSONS: This case report presents a patient with epidural LCH of the thoracic spinal cord, which can mimic spinal infections such as tuberculous spondylitis with abscess formation. Therefore, LCH could be considered as a possible diagnosis when a patient presents with features of infectious spondylitis with vertebral involvement.

RESUMO

RATIONALE: Low-grade malignant fibrous myxoid sarcoma (LGFMS) is a malignant tumor that originates from soft tissues and has specific clinical and histopathological characteristics. Paravertebral LGFMS is rarely reported. PATIENT CONCERNS: A 60-year-old woman had pain in the lower back and right anterior thigh for more than 3 years. DIAGNOSIS: Paravertebral LGFMS. INTERVENTIONS: Tumor resection, vertebral canal decompression and pedicle screw fixation. OUTCOMES: The tumor was excised, and the vertebral arch was fixed with pedicle screws at the root. Chemoradiotherapy was not performed. Her postoperative visual analogue scale (VAS) score decreased from 7 points at admission to 2 points at follow-up. The patient was discharged at postoperative day 13, and no recurrence was observed at the 6-month follow-up. LESSONS: Although LGFMS is rare, it should be considered in differential diagnosis of other soft tissue tumors to avoid misdiagnosis and inappropriate treatment.

RESUMO

Degenerative cervical myelopathy (DCM) is the leading cause of spinal cord dysfunction in adults worldwide. DCM encompasses various acquired (age-related) and congenital pathologies related to degeneration of the cervical spinal column, including hypertrophy and/or calcification of the ligaments, intervertebral discs and osseous tissues. These pathologies narrow the spinal canal, leading to chronic spinal cord compression and disability. Owing to the ageing population, rates of DCM are increasing. Expeditious diagnosis and treatment of DCM are needed to avoid permanent disability. Over the past 10 years, advances in basic science and in translational and clinical research have improved our understanding of the pathophysiology of DCM and helped delineate evidence-based practices for diagnosis and treatment. Surgical decompression is recommended for moderate and severe DCM; the best strategy for mild myelopathy remains unclear. Next-generation quantitative microstructural MRI and neurophysiological recordings promise to enable quantification of spinal cord tissue damage and help predict clinical outcomes. Here, we provide a comprehensive, evidence-based review of DCM, including its definition, epidemiology, pathophysiology, clinical presentation, diagnosis and differential diagnosis, and non-operative and operative management. With this Review, we aim to equip physicians across broad disciplines with the knowledge necessary to make a timely diagnosis of DCM, recognize the clinical features that influence management and identify when urgent surgical intervention is warranted.

RESUMO

OBJECTIVE: To identify and reveal the sensitivity and efficiency of dynamic somatosensory evoked potentials (DSSEPs) in the diagnosis of cervical spondylotic myelopathy (CSM). METHODS: This retrospective study included 31 CSM and 15 control patients. All patients received SSEP examination with stimulation of median and ulnar nerves at neutral, flexed, and extended cervical positions; latency and amplitude were recorded at the C2 and C5 spinous processes and in the scalp over the primary sensory area (C3'/4'). The percentage changes in latency and amplitude with dynamic motion were examined for each lead and compared between groups; the diagnostic cutoff values were determined using receiver operating characteristic curve analysis. RESULTS: All the patients with CSM received surgeries and were followed up for 1 year. Amplitude parameters varied with a dynamic position in both groups; all recorded dynamic SSEP indices except right median stimulus recorded at C5 spinous process, right ulnar stimulus recorded at scalp point C3, and right ulnar stimulus recorded at C2 spinous process were significantly different between groups (P < 0.05), but latency was not (P > 0.05). At the neutral position, the amplitude of left media stimulus recorded at C2 spinous process (LMC2) was associated with CSM, but with low diagnostic accuracy (area under the curve = 0.199). At a dynamic position, the percentage change in amplitude of LMC2 and of left ulnar stimulus recorded at C2 spinous process (LUC2) were determined to be diagnostic of CSM (P < 0.05), with areas under the curve of 0.891 and 0.912, respectively. Both records had high sensitivity and specificity in the diagnosis of CSM; the diagnostic cutoff values of LMC2 and LUC2 were calculated as 10.2% and 19.25%, respectively. CONCLUSIONS: The percentage change in amplitude was obvious during cervical dynamic motion, with records from LMC2 and LUC2 being predictive of CSM diagnosis; dynamic SSEPs provided a simple, accurate, and noninvasive supplementary test for the diagnosis of complicated CSM.

RESUMO

BACKGROUND: Systemic mastocytosis is a hematopoietic disorder of mast cell deposits in various systemic tissues that can include skin, spleen, liver, and bone marrow. When accumulation occurs within bone it has been reported to cause osteoporosis, osteosclerosis, or sometimes a mixed pattern. In exceptionally rare circumstances, it has been reported to present as an exophytic mass causing neural compression. CASE DESCRIPTION: A 72-year-old man was admitted with progressive worsening in his mobility and heavy and numb sensation in his bilateral lower limbs that worsened on walking. His weakness subsequently progressed such that he was no longer able to mobilize for 48 hours prior to admission. On examination he was found to be myelopathic with a sensory level noted at approximately the T10/11 area. Whole spine magnetic resonance imaging was conducted, which revealed a heterogeneous lesion involving the vertebral body and posterior elements of T10. The patient underwent T9-T11 laminecetomy with intralesional debulking of metastatic spinal column tumor. Postoperatively, the patient was noted to have improved anti-gravity power in the lower limbs. Intraoperative biopsy samples revealed focal paratrabecular infiltrates of abnormal mast cells with collagen fibrosis and focal bone destruction, along with cytogenetic features in keeping with systemic mastocytosis. CONCLUSIONS: We describe a rare case of systemic mastocytosis presenting as an extradural lesion causing compressive myelopathy and paraparesis. To our knowledge, this has only been described once before in literature. The patient underwent decompression surgery with improvement in neurology postoperatively. He was subsequently referred to the hematology team for further investigation and management.

RESUMO

OBJECTIVE: The cervical extensor musculature is important in cases of neck pain and loss of cervical lordosis after laminoplasty. Therefore, various surgical methods have been developed to preserve the muscle during laminoplasty. We have developed a posterior cervical muscle-preserving interspinous process (MIS) approach and decompression method. We have described the operation details and clinical outcomes of selected patients who have undergone this procedure. METHODS: The MIS approach and decompression method were performed in 20 consecutive patients who had only required central decompression for cervical stenosis. This procedure includes an approach to the interspinous space that is similar to Shiraishi's method but includes decompression without fracturing the spina bifida. RESULTS: The patients had no complications and did not require conversion to conventional laminoplasty. The mean operative time and mean blood loss was 53.0 minutes and 63.0 mL per level, respectively, and the mean hospital stay was 4.0 days. The mean preoperative and 3-month postoperative modified Japanese Orthopedic Association scores were 12.6 and 16.2, and the mean preoperative and 3-month postoperative neck disability index scores were 15.4 and 2.5, respectively. The postoperative neck visual analog scale score was 0.8. The mean preoperative and postoperative sagittal vertical axis was 1.6 and 1.8 cm, respectively. The mean loss of lordosis was 1.0°, and the mean cervical range of motion did not change from preoperatively to postoperatively. CONCLUSIONS: The MIS approach and decompression method was less invasive than both conventional laminoplasty and Shiraishi's selective laminectomy. It is a safe and effective minimally invasive technique for central stenosis caused by cervical spondylotic myelopathy.

RESUMO

Importance: Malignant spinal canal compression, a major complication of metastatic cancer, is managed with radiotherapy to maintain mobility and relieve pain, although there is no standard radiotherapy regimen. Objective: To evaluate whether single-fraction radiotherapy is noninferior to 5 fractions of radiotherapy. Design, Setting, and Participants: Multicenter noninferiority randomized clinical trial conducted in 42 UK and 5 Australian radiotherapy centers. Eligible patients (n = 686) had metastatic cancer with spinal cord or cauda equina compression, life expectancy greater than 8 weeks, and no previous radiotherapy to the same area. Patients were recruited between February 2008 and April 2016, with final follow-up in September 2017. Interventions: Patients were randomized to receive external beam single-fraction 8-Gy radiotherapy (n = 345) or 20 Gy of radiotherapy in 5 fractions over 5 consecutive days (n = 341). Main Outcomes and Measures: The primary end point was ambulatory status at week 8, based on a 4-point scale and classified as grade 1 (ambulatory without the use of aids and grade 5 of 5 muscle power) or grade 2 (ambulatory using aids or grade 4 of 5 muscle power). The noninferiority margin for the difference in ambulatory status was -11%. Secondary end points included ambulatory status at weeks 1, 4, and 12 and overall survival. Results: Among 686 randomized patients (median [interquartile range] age, 70 [64-77] years; 503 (73%) men; 44% had prostate cancer, 19% had lung cancer, and 12% had breast cancer), 342 (49.8%) were analyzed for the primary end point (255 patients died before the 8-week assessment). Ambulatory status grade 1 or 2 at week 8 was achieved by 115 of 166 (69.3%) patients in the single-fraction group vs 128 of 176 (72.7%) in the multifraction group (difference, -3.5% [1-sided 95% CI, -11.5% to ∞]; P value for noninferiority = .06). The difference in ambulatory status grade 1 or 2 in the single-fraction vs multifraction group was -0.4% (63.9% vs 64.3%; [1-sided 95% CI, -6.9 to ∞]; P value for noninferiority = .004) at week 1, -0.7% (66.8% vs 67.6%; [1-sided 95% CI, -8.1 to ∞]; P value for noninferiority = .01) at week 4, and 4.1% (71.8% vs 67.7%; [1-sided 95% CI, -4.6 to ∞]; P value for noninferiority = .002) at week 12. Overall survival rates at 12 weeks were 50% in the single-fraction group vs 55% in the multifraction group (stratified hazard ratio, 1.02 [95% CI, 0.74-1.41]). Of the 11 other secondary end points that were analyzed, the between-group differences were not statistically significant or did not meet noninferiority criterion. Conclusions and Relevance: Among patients with malignant metastatic solid tumors and spinal canal compression, a single radiotherapy dose, compared with a multifraction dose delivered over 5 days, did not meet the criterion for noninferiority for the primary outcome (ambulatory at 8 weeks). However, the extent to which the lower bound of the CI overlapped with the noninferiority margin should be considered when interpreting the clinical importance of this finding. Trial Registration: ISRCTN Identifiers: ISRCTN97555949 and ISRCTN97108008.

RESUMO

RATIONALE: Compressive myelopathy and compression fracture of aggressive vertebral hemangioma after parturition is a rare condition. Vertebral body compression fracture and high serum progesterone lead to extraosseous hemangioma enlargment cause narrowing the spinal canal which contribute to compressive myelopathy relate to pregnancy. PATIENT CONCERNS: We report a case of compressive myelopathy and compression fracture of aggressive vertebral hemangioma after parturition in a 35-year-old woman. The patient complained unable to walk and experienced intense pain in the back. DIAGNOSIS: Based on the clinical features and imaging studies, the patient underwent a T4-T6 laminectomy. Histopathology consistent with vertebral hemangioma. INTERVENTIONS: The patient underwent laminectomy for decompression. After subperiosteal dissection of the paraspinal muscles and exposure of the laminae, there was no involvement of the lamina by the tumor. The epidural tumor was removed through the spaces lateral to the thecal sac. Vertebroplasty was performed through T5 pedicles bilaterally and 7 ml of polymethylmethacrylate (PMMA) cement was injected. T4-T6 pedicle screw fixation was performed for segmental fixation and fusion. OUTCOMES: Six months after resection of the tumor the patient remained asymptomatic. She reported no low back pain and had returned to her normal daily activities, with no radiographic evidence of recurrence on MRI. Physical examination revealed that superficial and deep sensation was restored to normal levels in the lower extremities. LESSONS: The occurrence of compressive myelopathy of pregnancy related vertebral hemangiomas is quite unusual. It can lead to serious neurologic deficits if not treated immediately. So, prompt diagnosis is important in planning optimal therapy and preventing morbidity for patients.

RESUMO

RATIONALE: Chondrosarcoma of the sacrum is a highly unusual disease without standard curative managements yet. The objective of this study is to report a very rare case of chondrosarcoma of the sacrum successfully operated by percutaneous vertebroplasty. The management of these unique cases has yet to be well-documented. PATIENT CONCERNS: A 45-year-old woman presented with a five-month history of continuous and progressive pain and numbness of left extremity. A lytic, expanding lesion of the sacrum and paraspinal region with severe epidural spinal cord compression was identified. DIAGNOSIS: MRI of spine showed spinal cord compression secondary to the epidural componant of the giant mass, with increased marrow infiltration of the left S2 vertebral and paravertebral region, which presented as a solid tumor. Post-operative pathology confirmed the diagnosis of sacral well-differentiated chondrosarcoma (stage I B). INTERVENTIONS: The patient underwent percutaneous vertebroplasty and cement augmentation of sacrum via a posterior approach. OUTCOMES: The patient's neurological deficits improved significantly after the surgery, but the patient died of multiple systemic metastases at the 2-year follow-up visit. There were no complications associated with the operation during the follow-up period. LESSONS: Taken together, the lesion's clinical features, imaging results, and pathological characteristics are unique. Combined efforts of specialists from orthopedics, radiology, neurosurgery, pathology, and medical oncology led to the successful diagnosis and management of this patient. Giant sacral chondrosarcoma, although rare, should be part of the differential diagnosis when the patient presents with back pain and radiculopathy. We recommend the posterior approach for spinal decompression of the sacral chondrosarcoma when the tumor has caused neurological deficits or other severe symptoms. Osteoplasty by cement augmentation is also a good choice for surgical treatment.

RESUMO

Spinal schwannomas are benign tumors accounting for 30% of all spinal tumors. They originate from the shwann cells of the spinal roots. We report our experience in managing patients with spinal shwannomas, from diagnosis to treatment modalities, in the Department of Neurosurgery at the University Hospital Hassan II in Fez over a period of 13 years. The patients with spinal shwannomas accounted for 19.5% of those with spinal cord compression treated surgically over the same period. The average age of patients was 45 years, with a discreet female predominance. Spinal schwannomas had an insidious onset, then the median of consultation time was 18 months. The main symptoms were spinal and radicular pain. Half of our patients had neurological deficits. Medullary MRI was performed in all of our patients. Spinal schwannomas occurred predominantly in the chest (40%); 62% of shwannomas were intradural lesions, rarely extradural lesions (8%) and mixed lesions(4%). Complete Surgical resection was performed in 96% of cases with osteosynthesis in two cases and arthrodesis in a single case. Histological examination confirmed the diagnosis of benign neurinoma in 23 cases, malignant shwannoma in one case and neurofibroma in one case. Outcome was favorable in the majority of cases, two patients had complications, an infection of the wall and neurological worsening. The interest in the subject of our study is to highlight the features of these lesions and to compare the results of our case series with the data in the literature.

RESUMO

Cavernous haemangiomas are benign vascular malformations that can locate in the central nervous system. The epidural spinal location remains unusual. Pregnancy is known to be a precipitating factor. The aim of this study is to review general aspects of these lesions and specific facts about their relationship to pregnancy. A 32-year-old full-term pregnant woman is managed during early labor for a progressive spinal cord compression syndrome. After delivery, exploration by a lumbar MRI found an epidural vascular dorsal mass. Surgical exploration and histopathological examination confirmed the diagnosis of epidural cavernous haemangioma. The patient achieved complete recovery after 1 month. Spinal cavernous haemangiomas are rare malformations. Specific mechanisms seems to be involved in their growth during pregnancy. Although clinical and radiological presentation are spectacular and misleading, the prognosis is generally good, and urgent surgical treatment during pregnancy is usually not indicated.

RESUMO

Hepatocellular carcinoma (HCC) tumor is the most common primary hepatic cancer. Bone metastases are rare with an incidence varying from 2% to 20% during autopsy. Spinal cord compression secondary to HCC is exceptional (0.03%-1.52%). It represents a therapeutic emergency. Therefore, it must be systematically searched in case of neurological signs. We report here two new cases of spinal cord compression secondary to HCC with a review of the literature.

RESUMO

RATIONALE: Primary thoracic dumb-bell yolk sac tumor (YST) with both epidural and extraspinal extension is a rare disease with no standard curative managements yet. The objective of this study is to report a primary thoracic dumb-bell YST presenting with severe spinal cord compression successfully treated with posterior-only approach operation, followed by chemotherapy. The management of these unique cases has not been fully documented. PATIENT CONCERNS: A 26-mounth-old, previously healthy girl presented with progressive numbness and weakness of the lower extremities. Neurological examination revealed paralysis of both lower extremities, sensory disturbance below T-8 and bladder-bowel dysfunction. DIAGNOSIS: CT and MRI of spine showed a dumb-bell mass lesion with both epidural and extraspinal extension through enlarged intervertebral foramina and marked spinal cord compression at T7-T9. The AFP level was 13738 ng/ml. Preoperative puncture and Postoperative pathology confirmed the diagnosis of YST. INTERVENTIONS: By needle biopsy, we identified the pathological diagnosis is YST. Subsequently, the patient was treated with one-stage posterior-only approach operation, followed by 9 courses of chemotherapy based on cisplatin, bleomycin, etoposide. OUTCOMES: The patient has a complete neurologic recovery and remains recurrence free as of more than 2 years after the completion of operation. There were no other complications associated with the operation during the follow-up period. LESSONS: YST should be considered in the range of children with thoracic dumb-bell tumor presenting with spinal cord compression. Needle biopsy is valuable for preoperative diagnosis and design of the treatment strategy. If there is no evidence of CSF spread, metastasis or multiple diseases, it is effective to remove tumors as thoroughly as possible immediately, avoid further nerve injury and conduct enough chemotherapy. This case suggests that this treatment strategy is an effective option for primary YST with both epidural and extraspinal extension and severe spinal cord compression.

RESUMO

BACKGROUND It is still challenging to remove an epidural catheter in a postoperative patient receiving urgent antiplatelet and anticoagulation therapy for acute coronary syndrome. CASE REPORT While under general anesthesia combined with thoracic epidural anesthesia, a 72-year-old male patient underwent right radical nephrectomy for renal cell carcinoma. On postoperative day 1 (POD1), the patient experienced bradycardia and a decrease in blood pressure, and he was diagnosed acute myocardial infarction. Intra-aortic balloon pumping (IABP) was induced for cardiogenic shock, and urgent thrombus aspiration and coronary balloon angioplasty were performed. On POD3, the surgeon removed the epidural catheter under both antiplatelet and anticoagulation therapy. At that time, the platelet count was 45×109/L and the activated partial thromboplastin time (APTT) was 72.2 seconds. Four hours after the epidural catheter was removed, the patient complained of bilateral fatigue in legs and developed a loss of sensation. Six hours after the epidural catheter was removed, he developed motor paralysis and became completely paralyzed in both limbs after 9 hours. At 19 hours after the epidural catheter was removed, emergency magnetic resonance imaging detected a spinal epidural hematoma at the level of Th9-11 with compression of the spinal cord. Emergency laminectomy was performed to decompress and remove the spinal epidural hematoma at 18 hours after the onset of sensorimotor symptoms. After surgery and rehabilitation, these symptoms had only slightly improved. CONCLUSIONS In patients with urgent antithrombotic therapy for urgent percutaneous coronary intervention (PCI) with an IABP for acute coronary syndrome, the epidural catheter should not be removed until the IABP and heparin are discontinued, and platelet counts have recovered.

RESUMO

BACKGROUND: Cervical spine deformity in rhizomelic chondrodysplasia punctata (RCDP) has been described with different findings reported in the literature. However, available literature provides limited data from a few cases with magnetic resonance imaging (MRI) of the cervical spine. Our report describes the MRI findings in a group of children with RCDP, aiming to reach a better understanding of this pathology. METHODS: An Institutional Review Board-approved RCDP Registry was created at our institution with the goal of identifying pertinent medical issues over the lifespan of individuals with RCDP. Records of children within the registry were evaluated, and magnetic resonance images obtained between 2004 and 2015, were available for review. The levels of spinal canal stenosis were recorded and the severity of the stenosis was decided based on adults' parameters. Cord compression and myelomalacia were confirmed on the axial images. Sagittal lumbar spine magnetic resonance images were also evaluated when available, and the presence of tethered cord and fatty filum was recorded. RESULTS: Twenty-six children (15 boys and 11 girls) were identified in the RCDP Registry. Eleven children (6 boys and 5 girls) had sagittal MRI of the cervical spine available for review. Age at the time of MRI study was variable (1 wk to 32 mo). All patients except 1 had stenosis of the cervical spinal canal. Myelomalacia of the cord was noted only in this patient. CONCLUSIONS: This study suggests that, in children with RCDP, cervical spinal stenosis and cord compression are a real risk, and children with this diagnosis should have monitoring for these issues. Tethered cord is also a possible finding that needs to be evaluated. Full sagittal spine MRI is necessary to detect the possible deformities at the cervical and lumbar levels.

RESUMO

Ehlers-Danlos syndrome can be associated with cerebrospinal fluid (CSF) disturbances including recurrent CSF leak and Chiari I malformations. Persistent pseudomeningoceles are known to be associated with raised intracranial pressure. We present an unusual case of a compressive epidural CSF collection occurring after a computed tomography-guided L5 nerve root block and describe an effective management strategy.

RESUMO

BACKGROUND: Therapeutic intervention has recently been actively performed for metastatic spine tumor even though spinal cord paralysis is not clearly observed, but there has been no report in which the degree of spinal cord compression by tumor was taken into consideration for the paralysis-preventing effect of treatment. Thus, we investigated the neurological outcome after treatment of patients with spinal cord compression in a state of impending paralysis. METHODS: A retrospective cohort study. The subjects were 88 patients with epidural spinal cord compression (ESCC) scale 1b or severer compression with American Spinal Injury Association (ASIA) E spinal metastasis. The neurological outcome after the therapeutic intervention was investigated at regular intervals until death. The therapeutic intervention was posterior decompression and stabilization in 18 patients, stabilization without posterior decompression in 15, and radiotherapy in 55 patients (3 groups). RESULTS: The ASIA aggravation group was comprised of 15 patients, and the severity of paralysis was ASIA A in 3, B in 3, C in 6, and D in 3. Paralysis appeared in 16.7% in the posterior decompression and stabilization group, 13.3% in the posterior stabilization without decompression group, and 18.8% in the radiotherapy group. In the transverse view, the incidence was high in cases with advancement to the intervertebral foramen and circumferential-type advancement, and paralysis developed in more than 20% of ESCC 1c or severer cases. Factors influencing neurological aggravation were investigated, but there was no significant factor. CONCLUSION: In ESCC 1b or severer cases with ASIA E spinal metastasis, paralysis aggravated after therapeutic intervention in 16.7% in the posterior decompression and stabilization group, 13.3% in the stabilization without decompression group, and 16.7% in the radiotherapy group. There was no significant factor influencing the development of paralysis.

RESUMO

BACKGROUND: metastatic spinal cord compression (MSCC) is an oncology emergency. Prevalence is increasing. Treatment and care are complex and those diagnosed may be faced with life-changing challenges. AIMS: to review the impact and management of MSCC in patients with cancer, in order to analyse nursing considerations for supporting patients. METHODS: a literature review and thematic analysis of five primary research papers, published between 2009 and 2014. FINDINGS: two themes of prognosis/survival time and independence versus dependence were discovered. CONCLUSIONS: the onset of MSCC may result in paralysis and associated loss of independence, impacting on a patient's quality of life. Understanding individuals' prognosis and treatment/care preferences is fundamental for the sensitive, individualised support of patients with MSCC. The findings reinforce the nurses' role in health education, in order to raise awareness of MSCC and promote early diagnosis so that patients maintain function and independence as long as possible. The findings support the need for nurses to be equipped with appropriate communication skills to initiate and engage in sensitive, difficult and proactive conversations with patients and their families, supporting the delivery of humanised care.

RESUMO

BACKGROUND: Intradural extramedullary (IDEM) spinal masses are common lesions with varying histological diagnoses often associated with significant neurological deficits. This study aimed to describe the epidemiology, management and perioperative outcome of IDEM tumours seen at the teaching hospitals of the University of the Witwatersrand, Johannesburg, between 2014 and 2017. RESULTS: 92 patients were included in the study. The ages ranged from 21 to 87 years, sex ratio was M:F 1:1.4, and duration of symptoms prior to diagnosis ranged between 3 days to 18 months. Local and radicular type pain as well as motor weakness were the commonest symptoms. 67% had severe neurological deficit McCormick Grade III and IV. Schwannoma (26) Neurofibromas (21) and Meningiomas (16) and were the most frequent tumour types. Meningiomas predominantly occurred at the cranio-cervical and thoracic levels. Nerve sheath tumours were mostly found at the cervical and lumbar levels while filum terminale ependymomas occurred at the thoracolumbar area. Laminectomy was the commonest surgical approach employed, and the extent of resection varied, with total excision in half the cases. Neurological function was regained in 3 patients, deteriorated in two and was unchanged in the remainder. CONCLUSION: IDEM tumours are an important subset of spinal cord compressive lesions Presentation with severe neurological deficit is common and though resection is feasible neurological deficit remains in the vast majority. Earlier detection should improve the results of surgery.
