Angiographic manifestations of intracerebral cavernous hemangioma.

SummaryA case of intraventricular cavernous hemangioma is reported, with a review of the literature, especially that dealing with angiography of intracerebral lesions. Dense venous poolings and a localized area of venous stain were observed in this case.

Cavernous hemangioma in the pineal region

A cavernous hemangioma in the pineal region of a 22-year-old man is reported. Because the patient had diabetes insipidus and a contrast-medium-enhanced mass in his pineal region on computed tomography, a germinoma was suspected. A ventricular shunt was made and the tumor was irradiated, but without a response. After irradiation the tumor was entirely removed, and postoperatively the diabetes insipidus improved.

Facial hemangioma with cerebrovascular anomalies and cerebellar hypoplasia

A 5-year-old female patient with a left facial strawberry nevus, ipsilateral optic atrophy and cerebellar signs was observed. Computed tomography and cerebral angiography confirmed left cerebellar hypoplasia and cerebrovascular abnormalities such as internal carotid arterial stenosis, basilar artery occlusion, and a saccular aneurysm of left carotid siphon, all of which are presumed to develop congenitally. This case may represent a new variety of neurocutaneous syndrome which is different from other syndromes associated with facial hemangioma, such as the Sturge-Weber syndrome and the Wyburn-Mason syndrome.

Neuroradiological manifestations of suprasellar pituitary adenomas, meningiomas and craniopharyngiomas

SummaryThe radiological manifestations of 16 pituitary adenomas, six meningiomas and 14 craniopharyngiomas were reviewed. The differential diagnosis of these tumors is possible with a few exceptions when skull radiography, CT, angiography and metrizamide cisternography are carefully evaluated. Prolonged injection angiography (PIA) is particularly important for demonstrating the contours of pituitary adenomas and meningiomas. Metrizamide cisternography is indicated when the tumor contours are obscure using PIA, or when the differential diagnosis is uncertain.

Intracranial hypoglossal neurinoma: Report of a case

SummaryA case of intracranial hypoglossal neurinoma is reported. The diagnostic importance of an enlarged hypoglossal canal with isolated hypoglossal nerve palsy is emphasized. The computed tomography and angiographic findings are described.

Primary intracranial sarcomas: radiological diagnosis with emphasis on arteriography.

SummaryThe radiological manifestations of primary intracranial sarcomas may be non-specific and they vary widely according to their histological variations. Reticulum cell sarcomas, however, can be included in the differential diagnosis with a high degree of reliability when one observes a hypovascular mass with arterial encasement and deep medullary veins. Tumor vessels and tumor stains supplied by dilated feeding arteries suggest the possibility of a sarcoma of the brain or of the meninges in infants. Nine reticulum cell sarcomas, four undifferentiated sarcomas, and one fibrosarcoma are presented here with their radiological manifestations, especially on angiography.

Angiographic diagnosis of acoustic neurinomas and meningiomas in the cerebellopontine angle--a reappraisal.

SummaryForty-two acoustic neurinomas and seven meningiomas in the cerebellopontine angle were reviewed, and the radiological differential diagnosis of these tumors is discussed. Though enlarged internal auditory meati and characteristic CT findings were reasonably reliable indicators for the diagnosis of acoustic neurinomas, it was angiography which substantiated their correct diagnosis. An arcuate vein was frequently demonstrated with acoustic neurinomas, but never with meningiomas. Visualization of tangled veins seems to favor a diagnosis of acoustic neurinomas. Contrary to earlier reports, tumor stains were most frequently visualized using selective external carotid arteriography. The degree of tumor stains did not aid in differentiating acoustic neurinomas from meningiomas. The importance of using angiotomography, especially in the anteroposterior projection, and external carotid angiography during prolonged injections of large amounts of contrast media, is emphasized.

Circular enlargement of the optic canal caused by paranasal sinus mucocele.

Abstract A case of mucocele in the optic canal that caused visual impairment and headache is presented. On the radiograms, the optic canal was concentrically enlarged. There was no such case previously reported.

Intraspinal Meningioma in Childhood

This is a report of a surgically proven meningioma en plaque of the cervical region in a 10-year-old girl.

Thalamic hemorrhage in Moyamoya disease: a case report.

Case Report A 51-year-old woman was admitted to the Kyushu University Hospital because of unsteady gait. She had been in good health until March 28, 1978, when she suddenly developed headache, nausea, and vomiting. At that time the patient felt unsteadiness when walking and fell down without loss of consciousness. A facial cramp occurred occasionally on the right side. On the following day, headache, unsteady gait, and facial cramps persisted. Her appetite and eating habits were bizarre; for example : she ate dog food with her fingers. The symptoms had all subsided, except for
