Forty-two cases with intracranial hemorrhage caused by cerebral arteriovenous malformation (AVM), which was diagnosed by CT scan, were reviewed with regard to the clinical significance of intracranial hemorrhage, especially intraventricular hemorrhage (IVH). Twenty-one patients were defined as poor risk cases whose level of consciousness at admission was(More)
A rare case of fenestration of the intracranial internal carotid artery (ICA) was identified by angiography in a 51-year-old female with suspected subarachnoid hemorrhage.

We investigated clinical features of juvenile patients presenting non-herpetic viral acute encephalitis (4 men and 7 women, aged of onset; 23.7 +/- 3.3 years) without malignancy and immunodeficiency. We divided the patients into two groups according to initial neurological symptoms: psychiatric symptoms mimicking schizophrenia (group P, n=5), seizure (group(More)

To clarify the significance of fundus hemorrhage in the acute stage of intracranial hemorrhage due to cerebrovascular disease (HCVD), the incidence of such hemorrhage (retinal, preretinal, and subhyaloid hemorrhage) was examined and its correlations with the severity of the disturbance of consciousness and the prognosis were investigated.
