ABSTRACT
We describe a unique case of prolonged nausea and vomiting following posterior fossa craniotomy for removal of a meningioma. No apparent neurological or gastrointestinal causes were discovered except for a delayed gastric emptying time. The symptoms gradually resolved along with normalization of the gastric emptying time. Possible pathogenic mechanisms are discussed.

A 9-year-old boy presented with a 12-month history of headaches and recent grand mal seizures. Computed tomography and magnetic resonance imaging of the brain revealed an enhancing right frontal convexity lesion. The preoperative diagnosis was meningioma. However, histological examination was diagnostic of Rosai-Dorfman disease. Rosai-Dorfman disease confined to the intracranial compartment is very rare, of 34 reported cases only one presented in the first decade. Optimal treatment has not been established, but complete surgical resection alone seems effective and allows histological distinction from meningioma.
