[Intracerebral fibrous xanthosarcoma--report of a case]

A 61-year-old and right handed man was admitted to our department on August 11, 1980. The patient had three month history of focal fits, progressive hemiplegia, and motor dominant aphasia. The neuroradiological examination revealed a space taking lesion at the left frontoparietal area, which showed a small tumor stain with early filled draining vein on the left carotid angiogram, and iso-high dense mass with marked contrast enhancement on the CT scan. The EEG findings showed polymorphous delta rhythm in the left frontal and parietal areas. On August 28, total removal of the tumor was performed. The tumor was a intracerebral, fibrous cystic mass without involvement of the pia and dura mater. The removed tumor was measured approximately 6 X 5 X 4 cm in size, and consistence of the tumor was mostly elastic hard and partially soft and hemorrhagic. Histologically, the tumor composed of an admixture of bizarre histiocytes and fibroblasts, multinucleated giant cells, xanthoma cells and siderophages, with fibrous stroma. After surgery, no distinct lesion was demonstrated on the whole body CT scan and garium and technetium scintigram in the abdomen and the lung. The right hemiplegia and aphasia were improved gradually, and the patient discharged on December 20, 1980. We discussed the origin of this tumor, and angiographic and CT scan findings on the literature.
