A case of petrous bone myxoid chondrosarcoma associated with cerebellar hemorrhage.
We report a rare case in which a myxoid chondrosarcoma originated from the petrous bone and invaded the cerebellar hemisphere with hemorrhage. Neuroimaging showed the characteristic feature of multiple small cysts along the solid tumor, and the cystic formation was confirmed as a mucoid secretion by Alcian blue staining and electron microscopic examination. This tumor recurred following partial removal and stereotaxic radiosurgery.
