abstract: CT Scan has greatly helped preoperative diagnosis in brain tumors. CT Scan alterations are found in about 95% of brain tumors and the most modern instruments can pick-up even small alterations, locate them precisely and, in 80% to 90% of the cases can give their exact extension. But precise CT-scan diagnosis in brain tumors can be done in only 80% of the cases when in a supratentorial site; about 90% in infratentorial localizations. Differential diagnosis difficulties occur with metastasis, abscesses, infarction, meningiomas, and vessel malformations. Angiography does not always solve these diagnostic problems left uncovered by CT Scan and not infrequently surgical proof is necessary.
