Brain Infections 05
11 month old male with recent gastroenteritis treated with multiple antibiotics. Fever persisted along with adenoviral lymphadenitis, increasing irritability and depressed level of consciousness. An initial head MR was obtained. Over one month developed status epilepticus and HLH (hemophagocytic lymphohistiocytosis); a second MR was obtained 3 weeks later. Partially treated bacterial leptomeningeal infections are always difficult to diagnose, since CSF cultures are often unrevealing. MR flair, T1-w post contrast coronal, diffusion, SWI.
