Schwannomas are benign nerve sheath tumors that arise from Schwann cells, which responsible for producing the myelin surrounds nerves. They typically slow-growing and can occur in various locations body, including lumbar region of spine. We present a case giant invasive intradural extramedullary schwannoma managed with posterior interbody fusion (PLIF) laminectomy excellent results. A 58-year-o...

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...

an incidence that ranges from 0.26% to 0.30% of all herniated discs (1). Myelography, computed tomography (CT) and magnetic resonance imaging (MRI) are generally used to diagnose intradural lumbar disc herniation (IDLDH), but there can be some differences according to each case. Several studies have reported of a potential association between intradural disc herniation and gas within the spinal...

Echinococcus granulosus infrequently induces spinal hydatid cysts, and intradural hydatid cysts are extremely rare among these spinal hydatid cysts. We report a 30-year-old man with a history of progressive back pain caused by a previous back injury. Magnetic resonance imaging revealed a spinal intradural cystic lesion. After surgical removal, histopathological diagnosis was a hydatid cyst. The...

We report a rare complication of iatrogenic spinal intradural following minimally invasive extradural endoscopic procedues in the lumbo-sacral spines. To our knowledge, intradural cyst following epiduroscopy has not been reported in the literature. A 65-year-old woman with back pain related with previous lumbar disc surgery underwent endoscopic epidural neuroplasty and nerve block, but her back...

The literature on spinal vascular malformations contains a great deal of confusing terminology. Some of the nomenclature is inconsistent with the lesions described. Based on the experience of the senior author (R.F.S.) in the treatment of more than 130 spinal cord vascular lesions and based on a thorough review of the relevant literature, the authors propose a modified classification system for...

Background and Purposes. The 320-detector row CT scanner enables visualization of whole-brain hemodynamic information (dynamic CT angiography (CTA) derived from CT perfusion scans). However, arterial image quality in dynamic CTA (dCTA) is inferior to arterial image quality in standard CTA. This study evaluates whether the arterial image quality can be improved by using a total bolus extraction ...

Subependymoma is a rare benign CNS tumor (WHO grade I). The common sites of origin for this type of tumor are the lateral and the fourth ventricles. A spinal intramedullary location is rare. Radiological features of intramedullary subependymoma can mimic more common and more aggressive tumor types. We report a case of a 61-year-old male who presented with a 3-year history of low back pain, asso...

Primary melanocytic tumors of the central nervous system are rare. In this article the authors describe a case of C1C2 intradural extramedullary melanocytoma in a 43-year-old patient who presented with neck pain. C1-3 laminectomy was performed followed by excision of the lesion and an adjoining satellite nodule, along with the dural attachment. The histopathological features were consistent wit...

Primary spinal cord melanoma is a rare central nervous system malignant tumor. Usually it resembles an intradural extramedullary (IDEM) nerve sheath tumor or melanoma. We experienced a patient with upper thoracic primary IDEM spinal cord melanoma who was diagnosed to be with hydrocephalus and without intracranial lesions. Initial symptoms of the patient were related to the hydrocephalus and the...
