Computed tomography in craniopharyngiomas.

Computed tomographic examinations of 28 children and 12 adults with surgically proved craniopharyngiomas were retrospectively studied for characteristic findings that might be diagnostic of this tumor. It was found that 8 of 10 children and 2 of 4 adults examined pre-operatively had at least 2 of 3 findings: calcification, cyst, or contrast enhancement on CT. The remaining pre-operative patients did not receive contrast in their initial exams. Unusual presentation of the tumor in adults is also discussed.
