Summary:

Description	Radiopaedia case ID: 58346 Image ID: 35931903 Image stack position: 40/76 Plane projection: Axial Aux modality: SWI Study findings: On the blood-sensitive sequences there is signal drop-out in the left head of caudate corresponding to the site of previous hemorrhage. A microbleed is present in the right external capsule. No other macro- or microhemorrhages. No superficial siderosis There are dilated perivascular spaces within the basal ganglia visible on T2-weighted imaging. Mild periventricular and brainstem hyperintensities are seen, in-keeping with small vessel disease. Modality: MRI System: Central Nervous System Findings: Small focus of increased attenuation in the posterior left head of caudate in keeping with an acute hemorrhage. There is no perihaematomal edema or mass effect. No intraventricular, subarachnoid or subdural extension. Symmetrical high attenuation in both basal ganglia (visible on both brain and bone windows) in keeping with calcification. Mild generalized cerebral volume loss. No periventricular low attenuation or lacunar infarcts.
