A 64-year-old Japanese man who was diagnosed as having cerebral infarcts at an early clinical stage was found to have progressive multifocal leukoencephalopathy (PML). A decrease of leukocytes and lymphocytes had been detected in the previous year. During a total clinical course of 11 months, he showed marked depletion of lymphocytes ranging from 264/microL(More)
Six autopsy cases of subcortical hematoma caused by CAA were examined to elucidate the primary site of hemorrhage. Immunohistochemistry for amyloid beta-protein (A beta) revealed extensive CAA in the intrasulcal meningeal vessels rather than in the cerebral cortical vessels. All of the examined cases had multiple hematomas in the subarachnoid space, mainly(More)
We examined a solitary hematoma in a patient with sporadic cerebral amyloid angiopathy (CAA). The hematoma affected the middle frontal sulcus, cerebral cortex (CC) and subcortical frontal white matter (sfWM). We embedded the hematoma in four paraffin blocks, each of which was cut serially into 6-µm-thick sections. The first section and every 18th section(More)
The present study investigated the relationship between Au-antigen (AG) and Au-antibody (AB), and the effect of AB on the blood recipient. Abnormal liver function was observed in four out of 18 recipients. Two of the four cases received both AG. AB negative blood, one received AG (+) AB(--) blood, and the last received undetermined blood. Two of the four(More)
A 64-year-old man, who had been suspected as a hepatitis carrier 25 years ago and also was detected with a decrease of leukocytes and lymphocytes in the previous year, visited our hospital on 31 January, because of vertigo. Neurological status revealed normal findings. Blood cell count disclosed 4200 WBCs with a differential count of 66% segmented(More)
To clarify the frequency of CAA in the brain parenchyma and subarachnoid space (SAS), we counted sections of blood vessels showing positive staining for Aβ in the SAS, cerebral cortex (CC) and cerebral white matter (WM) using paraffin-embedded sections of the frontal, temporal and occipital lobes. The specimens had been taken for routine neuropathological(More)
