CT, angiography, and RN scans in intracranial cavernous hemangiomas.

Nine cases of surgically verified intracranial cavernous hemangiomas are reported. A comparison is made between radionuclide brain scans, angiography, and CT studies: RN scans are sometimes superior to angiography in indicating the presence of the lesion; CT is the most informative investigation, although it does not present a specific pattern. A preoperative specific diagnosis can only be suggested on the basis of the whole complex of the information available, including the clinical history.
