Computerized tomography of coagulation necrosis of the brain and brain tumors.

Diffuse contrast enhancement was observed on computerized tomography (CT) of coagulation necrosis of the brain and brain tumor. CT scans of delayed radiation necrosis of the brain seen in two patients showed a low absorption that was diffusely enhanced after an intravenous injection of contrast medium. Areas of central coagulation necrosis of anaplastic gliomas in two patients exhibited a marked contrast enhancement which was characterized by a prolonged increase in attenuation and a delayed elimination of the contrast medium.

Germinomas in the cerebral hemisphere.

Three patients with germinomas developing in the frontal lobe are reported. Common to the three cases, long-standing pyramidal signs were observed and the tumors simulated a cystic glioma containing xanthochromic fluid. The site of origin of these germinomas and the relation to suprasellar germinomas are discussed.

Morphological studies of hamster brain cells transformed in vitro by a human papovavirus BK.

The cytomorphology and cytogenesis of BK virus-transformed hamster brain cells (HBBK cells) were studied. HBBK cells with indistinct processes showed a tendency to epithelial arrangement as well as characteristics of malignant tumor cells in vitro, and developed long, delicate processes when cell growth was suppressed. Glial fibrillary acidic protein was demonstrated by immunofluorescence in the cytoplasm of almost all HBBK cells. The tumors arising in hamsters after subcutaneous inoculation of HBBK cells were classified as poorly differentiated gliomas. These findings suggest that selective transformation of glial cells in hamster brain cells by BK virus occurred.

[A case of spontaneous pontine hematoma in patient suspected of pontine glioma and multiple sclerosis (author's transl)].

A case of spontaneous pontine hematoma in young boy, with remitting and relapsing clinical course of up to 11 years, suspected of having pontine glioma or multiple sclerosis is reported. Differential diagnosis of these are mentioned with reference to our cases of pontine glioma. This patient was a man aged 16. At 5 years of age he had his first episode of double vision. 20 days after first episode, gait disturbance, left facial palsy and consciousness disturbance developed. Neurological and neuroradiological examination revealed a pontine glioma and radiotherapy was administered. All signs and symptoms resolved except for bilateral abducens palsy. Four months later, he again complained of gait disturbance and facial palsy. Examination revealed bilateral conjugate ocular palsy, left facial palsy and cerebellar ataxia. These symptoms again resolved spontaneously, except for bilateral abducens palsy. At age 16 years, having been asymptomatic for 10 years, he suddenly noticed loss of taste. At that time sensory disturbance of the left side of himself, right hearing disturbance, dysarthria and retardation urinae. Neurological examination revealed bilateral optic atropy, bilateral abducens palsy, left facial palsy, right hyperacuisis, dysarthria, left hemiparesis, hypesthesia of the left side of the body and left cerebellar ataxia. The vertebral angiography was no evidences of mass lesion and vascular anomalies. The computed tomography demonstrated a pontine hematoma. Conservative therapy was performed and these symptoms cleared off except for bilateral abducens palsy.
