Abstract

Metastatic brain tumors are known to produce the symptoms of stroke and intracranial high density areas are demonstrated by CT scan. But exact preoperative diagnosis is sometimes difficult. Recently, we have experienced three cases of metastatic brain tumors which began with the symptoms of vascular accident and were demonstrated as high density area by CT scan. Two of them are metastasis of lung cancer and another, hepatoma. Characteristic CT findings are as follow: 1) atypical location 2) non-homogeneous high density area extending from the margin of the tumor (sometimes ring-like appearance) 3) surrounding massive edema 4) positive contrast enhancement 5) multiple lesions Two of our cases were demonstrated the recurrence by CT scan which was performed at earlier postoperative stage. The dissemination of tumor cells in the hematoma was thought to be the main factor of it. We also discussed the operative procedures and the postoperative care.
