Abstract
Analysis of the CT [computed tomography] findings in 35 cases of [human] tumoral hemorrhage (taken from 973 intracranial tumors) revealed the following 3 distinct patterns of bleeding: hematoma, central hemorrhage and hemorrhagic infarction. The location, multiplicity of lesions and contrast enhancement are important in the diagnosis; the clinical history and arteriography may be helpful. The largest single group in this series consisted of 12 metastatic lesions; the others included glioblastoma (7), chromophobe adenoma (4), Grade I astrocytoma (3), medulloblastoma (3), central neuroblastoma (2), histiocytic lymphoma (3) and ependymoma (1). The relatively low mortality rate (21/35) despite marked neurological deterioration is attributed to prompt CT demonstration of hemorrhage followed by aggressive therapy (surgical evacuation, total resection, radiotherapy and/or steroids or mannitol).
