A Case of Intraventricular Plasma Cell Granuloma

A case of plasma cell granuloma in the right lateral ventricle simulating a meningioma of a 24-year-old man which was totally removed is presented. Plasma cell granuloma is a rare nonneoplastic lesion of unknown etiology which exclusively occurs in the lung. However on review of the English literature, only four prior cases of extrapulmonary plasma cell granulomas in the central nervous system have been reported.

Isolated Traumatic Ganglionic Hemorrhage

The authors present a series of 6 patients with isolated traumatic ganglionic hemorrhage. Although the patient population is small, some characteristic features of this rare type of traumatic lesion can be drawn. Isolated traumatic ganglionic hemorrhage differs from traumatic intracerebral hemorrhage or diffuse white matter injury, but also shares some features of both types of lesion. Some characteristic CT findings of isolated traumatic ganglionic hemorrhage are discussed. The prognosis of this lesion can be predicted by the degree of motor deficit and pupillary change with high accuracy.
