The predilection sites of cerebrovascular lesions (cerebral hemorrhage and/or softening) were studied in 1,278 stroke-prone spontaneously hypertensive rats (SHRSP). The precise supply to the main cerebral arteries was determined by trypan blue injections and microangiography. The three major territories were the anteromedial cortex, the occipital cortex, and the basal ganglia. A common angioar...

The basal ganglia and thalamus are paired deep gray matter structures that may be involved by a wide variety of disease entities. The basal ganglia are highly metabolically active and are symmetrically affected in toxic poisoning, metabolic abnormalities, and neurodegeneration with brain iron accumulation. Both the basal ganglia and thalamus may be affected by other systemic or metabolic diseas...

BACKGROUND A group study for symptomatic cavernous malformation (CM) treated with gamma knife (GK) surgery was performed. METHODS A total of 298 cases collected from 23 GK centers across Japan were included. Hemorrhage was the most common manifestation, followed by seizures and neurological deficits. Most of the lesions were located in the brainstem and basal ganglia, followed by the cerebral...

Neurological tumors, such as gliomas and meningiomas are rarely presented by movement disorders. Early detection of neurological both basal ganglia arising tumors ganglia-sparing ones, presenting with disorders is crucial to prevent any further deficits.

OBJECTIVE The clinico-radiologic features of the spontaneous basal ganglia hemorrhage (BGH) may often differ one from another, according to its regional location. Therefore, we attempted to classify the BGH into regional subgroups, and to extrapolate the distinct characteristics of each group of BGH. MATERIALS AND METHODS A total of 103 BGHs were analyzed by retrospective review of medical re...

BACKGROUND AND PURPOSE We investigated the residual abnormalities on computed tomography in a series of patients with proven intracerebral hemorrhage to determine whether the type of lesion is related to the site and size of the initial hematoma. METHODS In a partially prospective follow-up study, we studied computed tomographic scans of 42 patients with spontaneous intracerebral hemorrhage a...

Here, we report a rare case of an anaplastic astrocytoma masquerading as a hypertensive basal ganglia hemorrhage. A 69-year-old woman who had been under medical management for hypertension during the past 3 years suddenly developed right hemiparesis with dysarthria. Brain computed tomography (CT) scans with contrast and CT angiograms revealed an intracerebral hemorrhage (ICH) in the left basal ...
