A 23 year old woman with an intradural extramedullary enterogenous cyst in the cervical region, unassociated with vertebral cleft, presented with two episodes of neurological disturbance at an interval of five years. Subtotal excision of the anteriorly placed cyst at C6 vertebral level was followed by rapid and complete recovery.

Adult non-dysraphic intradural spinal lipomas are rare entities. Here we report two cases of adult non-dysraphic intradural lumbar lipoma. Case 1: A 66-year-old man experienced gradual progression of sensory disturbance and numbness in the lower extremities bilaterally over the course of 2 years. Magnetic resonance imaging (MRI) suggested an intradural lipoma at T12 with no evidence of dysraphi...

Intradural Lumbar disc herniation (IDLDH) is a known rare subgroup, accounting for 0.3% of all disc herniation. The incidence of IDDHs in 50-60 year olds is 2.2%, while that of 40-50 is only 0.2%. Most cases of reported intradural disc herniation (IDDH) are in the lumbar spine (92%), especially at L4-5 level (55%) with some reports in the cervical (5%) and thoracic (3%) spine. Chronic disease p...

We report a rare case of intradural primary osteosarcoma (IPOS) in a 74-year-old man with aphasia and right-sided hemiparesis. Radiologic workup revealed a large, partially calcified, left-sided frontotemporal intracranial mass lesion. At surgery, the tumor was found to be entirely intradural; it involved the brain and subarachnoid space of the left sylvian fissure. The adjacent dura was uninvo...

Bullet injuries to the spine may cause injury to the anatomical structures with or without neurologic deterioration. Most bullet injuries are acute, resulting from direct injury. However, in rare cases, delayed injury may occur, resulting in claudication. We report a case of intradural bullet at the L3-4 level with radiculopathy in a 30-year-old male. After surgical removal, radicular and claud...

Extraadrenal paragangliomas are usually located in the head and neck region, with 90% arising in the carotid body or glomus jugulare (1) . These tumors have also been located in a number of other areas, including, rarely , the spinal canal (1-7). Previously reported intraspinal paragangliomas have all been located in the intradural compartment in the region of the cauda equina, with the excepti...

A 41-year-old woman was evaluated because of a progressive myelopathy with bowel and bladder dysfunction. She had had a subtotal resection of a conus medullaris teratoma when she was 20 years old. Emergency myelography showed a large intradural mass at L 1L2 causing an almost complete block. Delayed CT scanning confirmed an intradural mass of soft-tissue density causing abrupt attenuation of th...
