 A punctate focus of restricted diffusion is seen in the posterior right cerebellum (601/233) with associated T2/FLAIR hyperintensity. This may represent a tiny focus of acute ischemia.There is a mild degree of periventricular and subcortical punctate hyperintense white matter lesions present identified on the FLAIR and T2 images. To lesser degree similar lesions are present in the brainstem and cerebellumA punctate focus of susceptibility signal is seen in the right temporal lobe, most likely representing mineralization versus hemosiderin from microhemorrhage. Also a punctate foci of susceptibility signal are identified in both frontal lobes.A focus of T1 high signal is seen in the right occipital lobe, most likely representing venous lakeThere is mucous retention cyst in the left maxillary sinus.
1. A punctate focus of restricted diffusion in the right cerebellum, may represent acute microinfarction.2. Periventricular and subcortical white matter punctate lesions as well as punctate lesions in the brainstem and cerebellum of a mild degree are nonspecific. At this age they are most likely vascular related.
