✓ The authors report a unique case of cervical chordoma in a 37-year-old woman without radiological evidence of bone involvement that was found to be totally intradural at surgery. Chordomas that are entirely extraosseous and intradural are extremely rare and in most of the cases described are located near the clivus. This is the first reported case of an intraspinal intradural chordoma.

✓ The authors report a unique case of a dermoid cyst that ruptured into the lumbosacral subarachnoid space following trauma, resulting in dissemination of cyst contents into the ventricles and cerebrospinal subarachnoid spaces. An intraspinous source should be considered when intraventricular fat is identified without a clear intracranial source.

✓ The authors report the investigation, treatment, and progress of a unique case of neurocutaneous melanosis with syringomyelia. The suspected etiology, the pathology, and the variable clinical manifestations of this rare phakomatosis are recounted. The potential for malignant change and the possible mechanisms of syrinx development in this syndrome are discussed.

✓ The authors recently encountered a unique case of anterior third ventricular neurocysticercosis in which the cyst exhibited an unusually high signal on T1-weighted magnetic resonance imaging. The lesion's signal intensity and location made differentiation from colloid cyst difficult. Intraventricular neurocysticercosis should be included in the differential diagnosis of a colloid cyst.

✓ Parathyroid carcinoma (PTC) is a rare pathological entity, with fewer than 400 reported cases. Intracranial metastasis of a PTC is exceptional; only five other cases have been identified in the English literature. The authors present a unique case of a patient with a solitary intracerebral metastasis of a PTC in an individual presumed to have hereditary hyperparathyroidism who had concomitant papillary and follicular carcinomas of the thyroid. The literature relevant to the management of these rare lesions is reviewed and discussed.

✓ A 33-year-old woman presented with upper respiratory obstruction due to a posterior pharyngeal mass, which was subtotally resected. The mass was a chordoma arising from the C-2 vertebral body. The patient then remained asymptomatic for 15 years before presenting with signs of cord compression. A chordoma, extending from C-1 to C-4, was again subtotally resected. The unusual biological behavior of this neoplasm is discussed, and a brief review of the pertinent literature is presented.

✓ The authors describe a case of subarachnoid hemorrhage from moyamoya-like vessels associated with an arteriovenous malformation (AVM) in a 44-year-old Hispanic man who presented with severe headache. The AVM was located in the left parietal lobe and the ipsilateral middle cerebral artery was occluded. Although the patient was initially neurologically intact, he began to experience neurological deficits from mild vasospasm, illustrating the sensitivity of the underperfused portion of brain surrounding an AVM. His neurological deficits improved with aggressive hydration and elevated blood pressure. After a 3-week period, the AVM was resected without complication and all of the patient's neurological deficits resolved. The authors review radiographic findings of this unique case.

✓ The authors report a unique case of diffuse spinal metastatic disease due to a pleomorphic rhabdomyosarcoma (RMS) in an adult. In additon to its overall rarity, peculiar characteristics of the particular tumor included its site of origin, demonstrated radiologically as the lumbar paravertebral musculature (psoas muscle) and the transcanalicular spread into the vertebral canal, resulting in thecal compression at multiple levels. The salient clinicopathological characteristics of RMS, as they related particularly to the spine, are subsequently discussed and a short review of the major therapeutic modalities for these tumors is offered.

✓ A unique case is presented of a third ventricle germinoma developing 3 years after total removal of an intrasellar teratoma. The third ventricle germinoma was not considered to be a recurrence or dissemination of the mature intrasellar teratoma but to have been transformed from multicenter germ cells present in the midline of the brain with different temporal development. The relevant literature is reviewed and the problems of management of patients with germ-cell tumors are discussed.
