Spinal extradural meningeal cyst has been rarely reported, whose etiologies are assumed to be the communication of cerebrospinal fluid (CSF) between intradural subarachnoid space and cyst due to the congenital defect in dura mater. Although the CSF communication due to this defect can be found in most case, few cases in which there is a lack of the communication have also been reported. We repo...
Background: Schwannomas are the most common extramedullary spinal tumors. The acute hemorrhagic onset of a spinal schwannoma is a rare occurrence. Case report: We report the case of a 32-year-old woman who presents with acute onset of quadriparesis due to a hemorrhagic intradural schwannoma. The tumor arose from left C1-C2 roots and extended downward from C1 to C5 vertebral levels. An emergency...
Spinal melanocytomas, first described in 1972,1 are rare pigmented tumors of the central nervous system commonly affecting females in their fifth decades. It commonly occurs in the posterior fossa, but spinal melanocytomas have also been reported in various locations with intradural intramedullary lesions being the rarest. Patients can present with varied symptomatology from mild backache, radi...
Spinal schwannomas are one of the most common intradural extramedullary spinal tumors. However, a string of bead-like intradural extramedullary schwannoma is highly uncommon. In the paper we present a case of a long-segment string of bead-like intradural extramedullary schwannoma of cauda equina from L2 to S2.The patient had been suffering progressive low back pain and sciatica with progressive...
We report a case of the coexistence of different spinal tumors at the same level of the cervical spine, without neurofibromatosis (NF), which was successfully treated with surgery. A 72-year-old female presented with right upper-limb clumsiness and weakness. Magnetic resonance imaging revealed an intradural, extramedullary tumor mass at the right C3-4 level with extradural extension into the in...
BACKGROUND AND PURPOSE When evaluating intradural tumor dissemination in the spine, contrast-enhanced T1-weighted 2D spin-echo (2D-SE) images are frequently problematic because most of the lesions are very small. Our purpose was to compare 2D-SE images with 3D gradient-echo (3D-GE) postcontrast images to determine which technique is better for depicting intradural tumor dissemination. METHODS...
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...
