Male, 63 years old, intracerebral hemorrhage. An acute hematoma is redemonstrated within the left basal ganglia which, accounting for differences in technique, has not substantially changed in size relative to the prior CT. This hematoma causes modest surrounding edema and mass effect with bulging of the insula into the Sylvian fissure. No clear evidence of any underlying enhancing or nonenhancing lesion is seen to account for this hematoma.Elsewhere in the brain, numerous periventricular and subcortical T2 hyperintense lesions are seen but without evidence of restricted diffusion. No pathologic intracranial enhancement is detected. The ventricular system remains patent allowing for minimal effacement of the left lateral ventricle. No other abnormal extra-axial fluid collections are seen.Mucosal thickening is demonstrated in the left maxillary sinus. Bone marrow signal characteristics are unremarkable.
1. Redemonstration of a left basal ganglia hematoma without significant interval change in size. No clear evidence of any underlying lesion is seen.2. Extensive scattered white matter lesions are seen which, although nonspecific, probably reflect chronic microvascular ischemic disease.
