Intradural Extramedullary Spinal Ependymoma: A Benign Pathology?
Spine, 2005
Intradural extramedullary spinal ependymomas are extremely rare. Herein, we describe a lesion-type spinal ependymoma that followed a malignant course, and discuss its clinical presentation, etiopathogenesis, and treatment. We present a patient who was diagnosed with an intradural extramedullary spinal tumor at T4-T6. The patient underwent gross total resection of the tumor without damage to the spinal cord. Histological examination, classified the lesion as a World Health Organization (WHO)-grade 2 ependymoma. One and a half years later, magnetic resonance imaging detected a recurring tumor at T4-T5. The tumor was removed and classified as a WHO-grade 3 anaplastic ependymoma. The patient was started on a course of regional spinal cord radiotherapy. The patient achieved tumoral control and clinical stabilization after the recurrence. We must consider the differential diagnosis of intradural extramedullary spinal tumors. The best treatment for this lesion is gross total resection and adjunctive radiotherapy is necessary in cases of malignant-change.

Ependymomas constitute 4-6% of primary central nervous system tumors. Spinal ependymomas are most frequently found in intramedullary region but few cases of intradural extramedullary ependymoma have also been reported. We report a 24-year-old male patient with a suspected case of intradural extramedullary ependymoma. Magnetic resonance images of the lumbar spine depicted an intradural mass from L1-L4 level. The spinal lesion was isointense on T1-weighted images and hyperintense on T2-weighted images, relative to the spinal cord. Laminectomy L1-L4 with gross-total excision was performed. Histopathological examination was inconclusive but suggested the possibility of ependymoma. Neurological recovery was initially observed but after few months symptoms worsened.
Extramedullary Intradural Spinal Tumors: A Pictorial Review
Current Problems in Diagnostic Radiology, 2007
Defining the location of tumors and mass lesions of the spine in relation to the spinal cord and the dura is of the utmost importance as certain types of lesions tend to occur in certain locations. The differential diagnostic considerations will vary according to location of the mass lesion as will the treatment and prognosis of these various lesions.
Intramedullary Spinal Cord Ependymomas in Children: Treatment, Results and Follow-Up
Pediatric Neurosurgery, 1998
A retrospective review of 20 pediatric patients with intramedullary spinal cord ependymomas, all of whom underwent operative resection between 1985 and 1996, was undertaken to determine surgical results, long-term follow-up and tumor recurrence. Twelve children operated on in the same period with filum or cauda equina ependymomas were not included in this study. Nine children had had previous treatment before referral. Gross total resection was achieved in 14 patients and subtotal in 6. None of these had a post-operative radiation therapy. The median follow-up period was 67 months (range 25–177 months). All children were clinically evaluated before and after operation and at the last follow-up. The clinical grade at the last follow-up showed improvement in 8 patients (40%), was unchanged in 10 (50%) and deteriorated in 2 (10%). Three patients had a recurrence, 2 at the primary site (2 and 3 years after our surgery) and 1 at a distant site (3 years after). The actuarial 5- and 10-yea...
Primary intramedullary non-Hodgkin’s lymphoma in an immunocompetent child
Spinal Cord, 2014
Study design: Case report. Objectives: Primary intramedullary spinal cord lymphoma is a rare entity. Studies have shown that there is a recent increase in the number of patients regardless of the status of the immunity. High index of suspicion should be kept in all patients with intramedullary tumors. Multidisciplinary approach at the earliest is required for best outcomes. Setting: Methods: We describe the case of an 11-year-old boy who presented with paraparesis and sensory loss below T10 level. On imaging, the dorsal spine showed intramedullary lesion mimicking an astrocytoma. Results: Surgical decompression of the tumor was done and histopathology showed non-Hodgkin's lymphoma, diffuse large B-cell type. There were no findings suggestive of congenital or acquired immunodeficiency. After complete staging evaluation, we instituted chemotherapy with modified DeAngelis protocol. At 2 years post treatment, he is in complete remission with near normal neurological status. Conclusions: Intramedullary spinal cord diffuse B-cell lymphoma in a pediatric age group is very rare and hence requires a high index of suspicion in patients presented with myelopathy. The outcomes are encouraging with current multidisciplinary approach. Spinal Cord (2014) 0, 000-000.

Extramedullary intradural spinal tumors are rare. Less than 15% of all central nervous system (CNS) tumors are spinal. Ninety percent of these patients are older than 20 years. Most of spinal tumors are extradural (50-55%) whereas 40-45% are intradural. Furthermore, 5% are intramedullary and 40% are extramedullary. Most common are Schwannomas (29%), followed by meningiomas (25%) and gliomas (22%). These tumors produce pain syndromes, a variety of neurological symptoms- motor, sensory, sphincter or a combination of thereof. All spinal levels may be involved. The diagnostics includes magnetic resonance imaging (MRI) including contrast enhancement, computerizing tomography (CT) scanning (bone windows with reconstruction) and possibly CT myelograms. Preferred treatment is the microsurgical radical resection. Perioperative mortality is very low as is serious morbidity.We herein discuss various aspects of presenting symptomatology, diagnostics, preoperative planning and tactics, surgical ...
A case of primary spinal intramedullary lymphoma
Surgical Neurology, 2001
A 41-year-old male presented to our clinic with a 1-month history of left hemiparesis. He had marked left arm weakness. The diagnostic work-up revealed an intramedullary mass at spinal level C2-4. Laminectomies were performed at C2-3-4 and the tumor was subtotally resected. Histological examination identified the mass as a non-Hodgkin’s diffuse B-cell lymphoma. The patient was treated with corticosteroids, chemotherapy,
Giant cystic intradural extramedullary pilocytic astrocytoma of Cauda equina
Journal of Neurosciences in Rural Practice, 2013
ABSTRACTAstrocytomas of Conus‑Cauda equina region are rare. Astrocytomas, which are intramedullary tumors, may rarely have an extramedullary component. However, primary intradural extramedullary astrocytomas are extremely rare, with very few cases reported in the literature. We describe a giant extramedullary pilocytic astrocytoma of Cauda equina in a 20‑year‑old male. To the best of our knowledge, this is the first report of such a case in the available literature. This case highlights the fact that astrocytomas can be primarily extramedullary and emphasizes the need to consider pilocytic astrocytoma in the differential diagnosis of cystic Cauda equina tumors.
