Due to the repeated falls and possible brain trauma, a noncontrast CT scan of the head (Figs. 1A and 1B) was obtained and was concerning for a subarachnoid hemorrhage (SAH).
42-year-old male with meningitis. MRI of the brain. Note marked swelling and enlargement of the cerebellum. The mass effect from the cerebellar swelling contributes to near-complete effacement of the fourth ventricle and effacement of the posterior fossa basal cisterns. The findings suggest rhomboencephalitis, given the history of meningitis and immunodeficiency.
