Acute Infarction, Mineralizing Lenticulostriate Angiopathy (Case Report)

Abstract

A three-year-old boy presented with left hemiparesis after an alleged fall at home. It was associated with gait disturbance, saliva drooling, and slurred speech. Physical examination revealed normal vital signs, left hemiparesis, and tongue deviation to the right side. Blood gases showed respiratory acidosis while other laboratory investigations were normal. Non-contrast computed tomography (CT) brain, electrocardiography, and echocardiography revealed no abnormalities. T2-weighted and FLAIR magnetic resonance imaging (MRI) brain showed signal hyperintensity at the right putamen extending to the right corona radiata. There was restricted diffusion on diffusion-weighted images and signal hypointensity on apparent diffusion coefficient maps, suggestive of an acute infarct. The diagnosis was revised to mineralizing lenticulostriate angiopathy. The patient was started on oral aspirin, physiotherapy, and occupational therapy, which helped him make a full recovery.
