Meningiomas are the second most common intradural spinal tumors accounting for 25% of all spinal tumors. Being a slow growing and invariably benign tumor, it responds favorably to surgical excision. In addition, spinal meningioma has low recurrence rates. However, we experienced a case of intradural extramedullary spinal meningioma which recurred 16 years after the initial surgery on a 64-year-...

Spinal intradural primary malignant peripheral nerve sheath tumors (MPNST) are rare in patients without neurofibromatosis. Here we represent a 3-year-old girl of primary intradural spinal malignant peripheral nerve sheath tumor. The tumor was removed partially and MPNST was diagnosed in the histopathological examination. Her condition deteriorated due to acute hydrocephalus in the following day...

Spinal intradural hemangiopericytoma is a very rare tumor and can be characterized by massive bleeding during surgeries, frequent recurrence, and metastasis. However, definite radiologic differential points of hemangiopericytoma are not known. We describe an unexpected hemangiopericytoma case with large bleeding and management of the tumor. A 21-year-old man visited complaining of progressive n...

BACKGROUND Ependymoma is a glial tumor that occurs in the central nervous system. The intradural extramedullary location of this neoplasm is very rare. The authors report a case of spinal intradural extramedullary ependymoma in a male and discuss its pathogenesis as well as its clinical, radiological, and therapeutical features. CASE DESCRIPTION A 31-year-old man was admitted at the author's ...

Granular cell tumor (GCT) of the spine is uncommon, with intradural extramedullary location being exceptionally rare. The non-specific clinical presentation and variable histologic patterns can make recognition of this tumor challenging. Two previous reports of GCT of the spine were reviewed (Medline 1960-2009) and analyzed with respect to this case report. The patients included two women and o...

Spinal schwannomas are benign tumors arising from spinal nerve root sheaths. These are the most common intradural extramedullary spinal tumors. Schwannomas are mostly solid or heterogeneous solid tumors. Cystic schwannomas are rare lesions. We present a 27-year-old woman with an intradural extramedullary cystic tumor in the lower thoracic region who complained of back pain and walking difficult...

BACKGROUND The authors report the case of a 53-year-old woman suffering from thoracic myelopathy caused by intraspinal dissemination of hemangiopericytoma. In literature, hemangiopericytoma is commonly found as an intracranial lesion, and often hematogenously metastasizes to the bone or liver; however, intradural spinal dissemination is extremely rare. CASE DESCRIPTION The patient presented w...

A 45-year-old woman presented with a rare case of metastatic cauda equina tumor from breast cancer without spinal column or brain metastasis. She had undergone resection of breast cancer 4 years previously. She presented with a 2-month history of severe low back pain. Magnetic resonance imaging showed a well-enhanced intradural extramedullary mass at the L1 level without other intradural lesion...

Hepatocellular carcinoma (HCC) is an aggressive tumor that frequently occurs in the setting of chronic liver disease and cirrhosis. Herein, we describe a case where a patient presented with acute onset cauda equina syndrome due to an intradural and extramedullary metastatic tumor bleeding from hepatocellular carcinoma (HCC). The patient had lower back pain that had radiated to the bilateral low...

Background and Importance: Capillary hemangiomas are benign tumors found on the skin soft tissues. They rarely present as an intradural spinal tumor. Common differential diagnosis methods schwannoma, hemangioblastoma, metastasis, paragangliomas. Case Presentation: We report a case of 38-year-old female with complaints lower backache radiation to limbs, in which magnetic resonance imaging reveal...
