Dermoids of the posterior fossa. Case reports and review.
Three children are presented with dermoid cysts of the posterior fossa, one of the most common locations of dermoid. They were initially diagnosed as having abscesses. Clinical presentations included hydrocephalus and recurrent meningitis. A helpful clue for identification is a bony defect of the skull on plain film or on a bone-window at Computed Tomography (CT).
