Female, 50 years old, with dizziness and abnormal head CT. Please note that due to patient discomfort, a limited examination was acquired consisting of axial diffusion, FLAIR and T2-weighted images as well as sagittal T1-weighted images.Signal abnormality is evident within the right thalamus consistent with the known hematoma. Accounting for differences in technique, there has been no significant interval change in size. The hematoma demonstrates expected diffusion signal abnormality. However, there are two punctate foci of restricted diffusion in the left periventricular white matter as well as a 1 cm focus of restricted diffusion involving the left cerebellar tonsil. Patchy periventricular FLAIR hyperintensity is seen. No evidence of significant generalized mass effect is detected apart from partial effacement of the right lateral ventricle. The ventricles are otherwise within normal limits
1.Limited examination due to patient discomfort.2.Redemonstration of a hematoma in the right thalamus without significant interval change.3.Given the presence of multiple foci of acute ischemia including in the left periventricular white matter and in the left cerebellar tonsil, the etiology of the hematoma is favored to be hypertensive in nature.
