Teratoma in the pterygopalatine fossa extending into the orbit: a case report.

An unusual case of intraorbital teratoma is presented. It was observed for the first time after 4 months when it caused increasing swelling of the maxillary region and proptosis of the eye. The diagnosis was difficult to establish. Repeated computed tomography scans were very helpful in evaluating the progress of the tumor. Surgical intervention with an infratemporal approach was undertaken and proved to be very successful.
