Abstract

Osteosarcomas are highly malignant bone tumors which commonly affect metaphyseal portions of long bones and those of the skull are distinctly rare as primary neoplasm. We report a case of recurrent osteosarcoma originated from the skull base which destructed sphenoid bone in two months. The CT and MR images of 28 years old man with headache, dizziness, and loss of touch sense in right buccal area showed 3-cm sized homogenously well-enhancing mass with internal small cystic portions. Craniotomy and mass excision was done and chemotherapy was combined for 1 month. After about 2 month, follow up MR images showed larger recurrent mass in original site and confirmed as the same osteosarcoma after 2nd operation.
