BACKGROUND We wanted to investigate the results of surgical treatment and analyze the factors that have an influence on the neurologic symptoms and prognosis of spinal intradural extramedullary (IDEM) tumors. METHODS The spinal IDEM tumor patients (11 cases) who had been treated by surgical excision and who were followed up more than 1 year were retrospectively analyzed. Pain was evaluated by...

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...

Intradural herniation of a cervical disc is rare; less than 35 cases have been reported to date. A 52-year-old man with preexisting ossification of posterior longitudinal ligament developed severe neck pain with Lt hemiparesis while asleep. Neurological exam was consistent with Brown-Séquard syndrome. Magnetic resonance images showed a C5-6 herniated disc that was adjacent to the ossified ligam...

Background Chordomas are rare, locally aggressive neoplasms thought to arise from notochordal remnants in the axial skeleton. Primary intradural chordomas are considered to be extremely rare. In this article a giant intradural petroclival chordoma is presented, and a synthesis of the available literature is performed to measure overall survival (OS) and recurrence-free survival (RFS) and to ide...

PURPOSE To evaluate the frequency and nature of spinal pathology, the frequency of clinically silent lesions, and the potential benefit of screening spinal MR in neurofibromatosis patients. PATIENTS AND METHODS 28 neurofibromatosis type-1 (NF-1) patients and nine neurofibromatosis type-2 (NF-2) patients were studied with postcontrast spinal MR imaging. RESULTS NF-1: One patient had a biopsy...

BACKGROUND Spinal cavernous malformations usually affect the vertebral bodies and are seldom intradural. Here, we report a rare spinal intradural-extramedullary cavernous malformation associated with extensive superficial siderosis along the neuraxis in a patient with radicular complaints. CASE DESCRIPTION A 60-year-old male presented with subacute headaches, intermittent fever, and acute bac...

Several classifications have been proposed for spinal AVMs.[2],[4]-[6] They can be divided into intramedullary AVMs and arteriovenous fistulas (AVFs). Based on anatomical characteristics, spinal AVFs are classified as extradural AVFs and intradural lesions, including spinal dural AVFs (SDAVFs) and perimedullary spinal AVFs (PMAVFs).[7],[8] Rangel-Castilla et al. classified extradural AVFs as ty...
