introduction: the aim of this study was to report surgical strategies and clinical outcomes for thoraco-lumbar intradural lipomas. intraspinal lipomas are rare congenital histologically benign neoplasms, which account for less than 1% of all spinal cord tumors. these tumors are most frequently found in the lumbosacral area as components of a dysraphic state, however, intramedullary lipomas are ...

STUDY DESIGN A retrospective study of intradural extramedullary tumor. OBJECTIVE To compare the treatment results in the different surgeries of spinal intradural extramedullary tumor. METHODS The study retrospectively reviewed 122 patients. The minimally invasive surgery (MIS) group was divided into Group A (hemilaminectomy + tumor microscopic excision) and Group B (laminectomy + tumor micr...

Background and Importance: Disk sequestration can be defined as a herniated disk with perforation of the fibrous ring (or outermost annulus fibrosus) and posterior longitudinal ligament with migration of the disk fragment to the epidural space. Even after the introduction of high-resolution magnetic resonance imaging (MRI), it is still frequently misinterpreted as neoplastic masses. U...

Background: There are several non-neoplastic lesions which mimic intradural extramedullary spinal cord neoplasm in their radiographic and clinical presentation. Intradural granulomas that form within the dura mater, is outermost protective layer surrounding cord. Variety of infections, such as Tuberculosis or Fungal infections (histoplasmosis coccidioidomycosis), inflammatory conditions, sarcoi...

Intradural lumbar disc herniation is a rare pathological entity. The pathogenesis of intradural lumbar disc herniation is not known clearly. Intradural disc herniations usually occurred at the L4-L5 levels but have also been reported at other levels. However, intradural disc herniation at L5-S1 is quite rare. There are approximately nine reports in the English literature of intraradicular disc ...

Patients with spinal abnormalities infrequently present with intradural intramedullary bleeding. The more common causes include spinal trauma, arteriovenous malformations and saccular aneurysms of spinal arteries. On occasion, spinal cord tumors either primary or metastatic may cause intramedullary bleed with ependymoma of the conus medullaris. Spinal nerve sheath tumors such as schwannomas onl...

A 36-year-old female patient presented with shoulder pain experienced over a period of one year and progressive weakness in both legs for one month. A magnetic resonance imaging scan revealed an intradural extramedullary (IDEM) fusiform mass about 9.8 cm in length, heterogeneously enhanced at the level of C6-T4 with spinal cord compression. At the time of surgery, the surgeon found an encapsula...

Meningiomas are mostly benign intradural tumors. Concerning the spine, some of them can extend outside canal or even develop extradurally but their primary attach is often located in vertebral canal. Here we present case an exceptional purely intraforaminal meningioma mimicking a neurogenic tumor, involving artery and presenting with cervicobrachial neuralgia slight motor deficit.

Primary intradural extraskeletal Ewing sarcoma is a very rare form of malignant neoplasm. Only few cases have been reported on the literature. Here, we report a case of a 14-year-old boy who had a chief complaint of pain and tingling in the right lower limb. The patient initially seemed to have a giant nerve sheath tumor but was eventually diagnosed with intradural extraskeletal Ewing sarcoma a...
