  • A case of intradural extramedullary cavernous angioma is presented with headache, dizziness, and bilateral sensorineural hearing loss caused by an intracranial superficial hemosiderosis. It was incidentally found in a patient with a 3-month history of sustained headache, dizziness and a 3-year history of hearing difficulty. The neurological examination was unremarkable in the lower extremity. MR images showed an intracranial superficial hemosiderosis mostly in the cerebellar region. Myelography and MR images of the thoracolumbar spine revealed an intradural extramedullary mass, which was pathologically proven to be a cavernous angioma. T12 total laminoplastic laminotomy and total tumor removal were performed without any neurologic deficits. The patient's symptoms, including headache and dizziness, have been absent for three years. Intradural extramedullary cavernous angioma can present with an intracranial superficial hemosiderosis as a result of chronic subarachnoid hemorrhage.

  • A 42-year-old female was admitted with an 11-month history of progressive spastic paraparesis and ataxic gait. Magnetic resonance imaging showed intraspinal space occupying lesion compressing the spinal cord posteriorly, located from C5 to T2 with iso to high signal intensity at T2-weighted images and high signal intensity at T1-weighted images. The patient underwent surgery for decompression of the affected spinal cord because of the progressive neurological deficit. At surgery, the lesion was intradural extramedullary lipoma composed with mature adipose tissue. Partial tumor removal to decompress the neural structures and laminoplasty to avoid postoperative instability and deformity were performed. Postoperatively, she demonstrated improvement in paraparesis and was able to walk without assistance. Though attempts to decrease the size of or even to totally remove a lipoma are not required to achieve satisfactory results and carry considerable risks of surgical morbidity, a careful and limited decompression of the affected spinal cord through a partial removal of the tumor and laminoplasty could result in a significant neurological improvement.

  • Granular cell tumors (GrCTs) of the spinal cord are rare benign tumors with a high rate of local recurrence. Only 6 cases of spinal GrCTs have been reported. GrCT is difficult to distinguish from other benign tumors such as schwannoma using imaging. A radiological "speckled dots" sign may be a useful differentiating feature of GrCT based upon experience with two cases and a review of the literature.

  • Spinal intradural extramedullary teratoma is a rare condition that develops more commonly in children than in adults and may be associated with spinal dysraphism. We report a rare case of adult-onset intradural extramedullary teratoma in the thoracolumbar spinal cord with no evidence of spinal dysraphism and without the history of prior spinal surgery. The patient was a 38-year-old male whose chief complaint was urinary incontinence. X-ray images of the thoracolumbar spine showed the widening of the interpedicular distance and posterior marginal erosion of the vertebral bodies and pedicles at the T11, T12, and L1 level. Magnetic resonance imagings of the lumbar spine showed a lobulated inhomogeneous high signal intradural mass ($87{\times}29{\times}20mm$) between T11 and L1 and a high signal fluid collection at the T11 level. Laminectomy of the T11- L1 region was performed, and the mass was subtotally excised. The resected tumor was histopathologically diagnosed as a mature cystic teratoma. The patient's symptom of urinary incontinence was improved following the surgery.

  • It has been known that hemangioblastoma of spinal cord occurs about 4% of all the spinal tumors. The authors present a rare case of intradural extramedullary(IDEM) hemangioblastoma of distal spinal cord in 41-year-old male patient. This IDEM mass at the level of conus medullaris showed iso-signal intensities on T1-weighted image(T1-WI) and high-signal intensities on T2-WI, and was enhanced homogeneously on MRI. At surgery, T12- L1 total laminectomy and enbloc mass removal were performed. This IDEM hemangioblastoma was confirmed by histopathologic findings. For less postoperative complication in IDEM tumors, we suggest that precise preoperative evaluation and complete excision via proper surgical approach to distal conus should be reemphasized.

  • We report a rare case of primary intradural extramedullary myxopapillary ependymoma of the spinal cord. A 45-year-old woman was admitted to the author's institution with a history of progressive paraparesis[grade IV/IV] with back pain. Neurologic examination revealed decreased sensation below T12 sensory dermatome level. Magnetic resonance imaging[MRI] revealed an intermediate enhanced intradural extramedullary tumor extending from T12. Total resection of the tumor was achieved by T12 laminectomy. Intraoperatively, there was no finding of attachment to rootlet and dura. Histopathological examination identified the tumor as a myxopaillary ependymoma. To the best of my knowledge, this is the first reported case of primary intradural extramedullary ependymoma in Korea.

  • Pure ventral midline giant schwannoma is an extremely rare entity. Spinal intradural extramedullary schwannomas commonly occur posterolateral or anterolateral to the spinal cord. A case of a pure midline ventrally situated giant pan cervical extramedullary schwannoma in an 18-year-old male patient with compressive myelopathy and sphincter involvement is presented. Spinal MR imaging showed a midline ventrally situated extramedullary tumor with severe spinal cord compression extending from clivus to C7 vertebra. It was resected through a posterolateral approach. Histology was consistent with a schwannoma. Post operative MR imaging showed no evidence of the tumor. The radiological features, pathogenesis and surgical strategies in management of these difficult tumors are discussed and the relevant literature is briefly reviewed.

  • Solitary fibrous tumor is rare benign mesenchymal neoplasm. The spinal solitary fibrous tumor is extremely rare. The authors experienced a case of intramedullary solitary fibrous tumor of cervicothoracic spinal cord in a 48-year-old man with right lower extremity sensory disturbance. Spinal MRI showed intradural mass lesion in the level of C7-T1, the margin between the spinal cord and tumor was not clear on MRI. A Left unilateral laminectomy and mass removal was performed. Intra operative finding, the tumor boundary was unclear from spinal cord and it had intramedullary and extramedullary portion. After surgery, patient had good recovery and had uneventful prognosis. Follow up spinal MRI showed no recurrence of tumor.

  • Spinal intradural cysticercosis is a rare manifestation of neurocysticercosis that may present as an isolated lesion. We report a case of sacral intradural cysticercosis misdiagnosed as a metastasis through cerebrospinal fluid seeding in a 48-year-old patient who underwent ependymoma surgery 3 months ago. We performed S1-2 laminectomy with the total removal of intradural lesion. The cysticercosis was confirmed histologically. The patient was given albendazole with corticosteroid.
