[Brain tumors associated with hemorrhage from tumors as their first manifestation].

Four cases of brain tumors associated with hemorrhage from tumors as their first manifestation were reported. These were malignant astrocytoma in two cases, brain metastasis of hepatocellular carcinoma in one case and skull metastasis of hepatocellular carcinoma in one case. Clinical symptoms and sings were generalized convulsion, sudden onset of headache, vomiting and hemiparesis. It was difficult to confirm the diagnosis of brain tumors in such cases. Therefore it is important to perform follow-up plain and enhanced CT repeatedly and it is also important to make adequate biopsy of hematoma wall and surrounding tissue during operation.
