Occipitocondylar hyperplasia and syringomyelia presenting with facial pain.

The authors describe a unique presentation and long-term management of a rare craniovertebral abnormality in a patient presenting to their institution. This 10-year-old girl presented with right-sided facial pain and subjective dysesthesia of the chest wall without evidence of cervical myelopathy. She was found to have extensive cervicothoracic syringomyelia secondary to compression at the foramen magnum by hypertrophic occipital condyles.

Acute external hydrocephalus complicating craniocervical decompression for syringomyelia-Chiari I complex: case report and review of the literature.

The occurrence of subdural cerebrospinal fluid collections and ventricular dilatation (external hydrocephalus) after foramen magnum decompression is extremely rare. The authors report on a 37-year-old man who developed symptomatic subdural fluid collections (SFC) after uncomplicated foramen magnum decompression for Chiari I-syringomyelia complex. Postoperative magnetic resonance imaging revealed a supratentorial SFC with prominent midline shift.

Epidural meningioma of the sacral canal. Case report.

Spinal meningiomas are reported infrequently as pure epidural tumors, and they are rarely located at the caudal end of the spine. The unique combination of a wholly epidural tumor confined entirely to the sacral canal has not been previously described. The authors describe the case of a 29-year-old man who presented with coccygeal and left-sided S2-4 dermatomal pain.
