Five cases of histologically verified cavernous angiomas of the spinal cord are reported. Acute lower-extremity sensory disturbance was the initial symptom in four patients, and one presented with weakness of the hand. Progressive neurological deficit occurred in all patients, but the clinical course and outcome were extremely variable. Myelography revealed(More)

Meningeal melanocytomas are rare tumors of the central nervous system that are found almost exclusively in the posterior fossa and spinal cord and whose natural history is poorly defined. In this report, the authors review the clinical presentation, radiological appearance, operative findings, and histological features in two cases of meningeal(More)
In three patients with histologically proved cavernous hemangiomas of the spinal cord, magnetic resonance (MR) imaging was superior to myelography, delayed computed tomography (CT) myelography, and contrast-enhanced CT in depicting the lesion. The presence of mixed subacute and chronic hemorrhage, suggested by mixed high- and low-signal-intensity components(More)
Choroid plexus papillomas are rare intracranial neoplasms that are generally benign in nature. They are seen in both children and adults and have a male preponderance. Magnetic resonance imaging, a noninvasive diagnostic tool, demonstrated the intraventricular location and the surrounding anatomy with striking clarity, more effectively than angiography and(More)
Spontaneous spinal epidural hematomas are well-recognized but rare entities. The standard treatment for these hematomas has been prompt surgical evacuation. The authors report a case of a 76-year-old man who precipitously became paraplegic secondary to a spontaneous spinal epidural hematoma and then experienced the complete resolution of his neurological(More)
A 15-year-old boy was admitted to excision of a large exophytic right parietal tumor, which, on computed tomography scans and angiograms, revealed marked contrast-medium enhancement in infusion studies. Angiographic studies showed meningeal feeders, which suggested a meningioma. Computed tomography scans demonstrated extensive erosion of the skull, which(More)
The position of the medial internal capsular border (lateral thalamic border) in relation to the width of the third ventricle is of considerable importance to stereotactic surgeons. Close estimation of its position from anteroposterior roentgenograms diminishes the possibility of multiple brain penetrations in an attempt to find it by electrophysiological(More)
