We would like to report a rare case of pontine @entity11 with unusual neuroimaging features. The @entity1 was a 3-year-old @entity1 who suffered from chronic @entity390 and gait disturbance for several months. Computed tomography (CT) demonstrated @entity2554 , and ventricular peritoneal (VP) shunt was performed for idiopathic @entity1276 at another hospital. Fever of unknown origin continued for a month after the VP shunt. At our hospital, cerebrospinal fluid examination showed @entity4008 , and it was assumed that shunt infection lead to shunt failure. Magnetic resonance imaging (MRI) revealed @entity1276 and pontine swelling, and serial MRI suggested @entity5 extending to the bilateral thalamus. The @entity1 underwent stereotactic biopsy of the left @entity5 , under general anesthesia, and the histological diagnosis was @entity816 . Diffuse pontine @entity11 rarely increases without @entity129 . In the present case, pontine @entity11 extended to the bilateral thalamus symmetrically. It was difficult to diagnose the presented lesion as pontine @entity11 in the early period because of its unusual neuroimaging.
