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...

Although cavernous hemangiomas occur frequently in the intracranial structures, they are rare in the spine. Most of spinal hemangiomas are vertebral origin and "pure" epidural hemangiomas not originating from the vertebral bone are very rare. Our spinal hemangioma case is extremely rare because of its "pure" epidural involvement and intralesional hemorrhage. A 64-year-old man presented with pro...

Background: Spinal navigation offers significant benefits in the surgical treatment of small thoracic intradural tumors. It enables precise tumor localization without subjecting patient to high radiation doses. In addition, it allows for a smaller skin incision, reduced muscle stripping, and limited bone removal, thereby minimizing risk iatrogenic instability, blood loss, postoperative pain, en...

BACKGROUND AND PURPOSE Postoperative MR imaging is routinely performed for staging of medulloblastoma because of frequent tumor dissemination along CSF pathways. The goals of this study were to: 1) determine the timing of disease occurrence and contrast-enhanced MR imaging features of disseminated medulloblastoma involving the spine and their relationship to patient outcomes; and 2) compare the...

background & importance: cavernous angiomas are typically superficial lesionscreated by anomalous vessels and found in the skin or mucosa, but intradural locations are rare especially in the spine. we report a case of the spinal intradural cavernous angiomas of the lumbar spine. case presentation: a 53-year-old man presented with a 6-month history of low back pain and bilateral radicular pain. ...

A case of extramedullary spinal root hemangioblastoma is described. A 44-year-old male presented with gait disturbance. Magnetic resonance (MR) imaging revealed a round enhanced mass at the level of T8. Spinal angiography showed a vascular tumor fed by the posterior spinal artery via the left T9 intercostal artery. A laminectomy of T8-T9 was performed, and a reddish brown-colored soft tumor ori...

Intramedullary schwannomas are a rare form of spinal tumors. Here, we present case 61-year-old woman who was admitted to our hospital with complaints weakness in both lower extremities, numbness, urinary and defecation disorders, radiculating back pain. Physical examination revealed sensory motoric deficits the as well autonomical dysfunctions. Radiological imaging mass at level thoracic segmen...

Neurofibromas are occasionally present in spinal roots; however, an intramedullary neurofibroma is especially rare. Although a few cases of intramedullary neurofibromas in cervical spinal cord have been reported, to the best of our knowledge, there are no reports of intramedullary neurofibromas in thoracic spinal cord, and moreover, no reports have clearly reported immunohistochemical findings....

Background: Spinal cord injury (SCI) stimulates an inflammatory reaction that causes substantial secondary damage inside the injured spinal tissue. The purpose of this study was to determine the anti-inflammatory effects of epigallocatechin gallate (EGCG) on traumatized spinal cord. Methods: Rats were randomly divided into four groups of 12 rats each as follow: sham-operated group, trauma group...
