Pseudocystic cryptococcal meningitis complicated by transient periaqueductal obstruction in a child with HIV infection

We describe a 10-year-old human immune deficiency virus (HIV) infected girl who presented with pseudocystic cryptococcal meningitis complicated by hydrocephalus secondary to aqueductal obstruction. The neuroradiological features of this case are presented and we also postulate on the pathogenesis of the type of hydrocephalus encountered.
