Ossifying parasellar chondroma. Case report.

The Authors report a case of cartilaginous tumor of the parasellar region, diagnosed as ossifying chondroma by virtue of the intense calcification it presented. Preoperative diagnosis was suggested by CT, which showed a characteristic honeycomb conformation, with alternate areas of greater or lesser density, without contrast enhancement. Angiography is, however, essential in planning the operation, which must on occasion be confined to partial resection only. This limitation may be acceptable where functionally important areas are concerned, since these neoplasms show an apparent tendency to only modest growth.
