A 75 year old woman developed the acute onset of ataxia, diplopia and confusion.
Axial CT scan 3 days later. Along with the infarctions present in the cerebellum and brainstem, note the dilatation of the lateral ventricles, indicating early obstructive, non-communicating hydrocephalus. This is a known, potentially fatal complication of posterior circulation stroke. Infarction leads to edema which can then compress the fourth ventricle and/or cerebral aqueduct. If not recognized, hydrocephalus may develop and lead to brain herniation and death.
