The case reported here was a 6-year-old girl who complained of sudden headache and nausea followed by vomiting and visited our clinic. Physical examination revealed mental confusion, right abducent palsy and papilledema. Computed tomography demonstrated a round high-density area surrounded by a low-density zone indicating cystic nature and including high-density part. The lesion was located in the right parietal lobe attaching to the flax. Right frontoparietal craniotomy disclosed a brain tumor containing a large cyst in which bleeding from the tumor was confirmed. This mass lesion was totally resected out. Histo-pathological diagnosis was meningioma to contained cystic formation and hemorrhage from the tumor. Therefore, further discussion on the pathogenesis of cyst formation and bleeding from this tumor was presented.
