A 10-month-old boy, previously healthy, began vomiting during a meal and became unresponsive. The CT scan demonstrated acute hydrocephalus and a large fourth ventricular tumor. This 6 cm. posterior fossa mass showed striking fluid levels and hemorrhagic products as well as relatively little enhancement as the dominant features. Suboccipital craniotomy was performed to resect the tumor. Specimens were sent to pathology for frozen diagnosis and permanent evaluation.
