Abstract

Primary intracranial mesenchymal chondrosarcoma (MCS) is very rare neoplasm and it is difficult to differentiate from meningioma or hemangiopericytoma due to its rarity and indistinctive radiologic features. A 29-year-old woman was admitted to the hospital with 3 month history of headache. CT scans revealed a 5.5×4.0 cm-sized hyperdense mass with intratumoral calcification at right frontal lobe. On MRI, the tumor represented iso to low signal intensities on both T1-and T2-weighted images and intense enhancement. Complete extirpation was done. The histopathologic examination established the diagnosis of MCS. Typical primary intracranial MCSs occur in supratentorial area, most often in the frontoparietal region. Usually, MCSs are hypervascular, attached to the meninges, and occasionally accompanied osteolytic bony defect. In our case, tumor was not attached to meninges, and there was no osteolytic lesion. The preferred treatment is radical resection. The benefit of radiotherapy and chemotherapy remains controversial.
