The patient was admitted to the hospital, aggressively supported, and treated with broad-spectrum antibiotics, piperacillin, and vancomycin. (May 20, 2013) Focal areas of signal intensity (FASI), also known as focal abnormal signal intensity or unidentified bright objects (UBO), are bright areas on T2-weighted images commonly identified in the basal ganglia (often the globus pallidus), thalamus, brainstem (pons), cerebellum, and subcortical white matter in children with. 2.3).
