[A case of embryonal carcinoma arising in the basal ganglia of the cerebrum].
The occurrence sites of intracranial primary germ cell tumors are most often the pineal and suprasellar regions. The histological type observed most frequently in these tumors is germinoma. Cases of embryonal carcinoma arising in the basal ganglia are rarely reported. To our knowledge, only 4 such cases have been previously reported in the literature. A case of an embryonal carcinoma arising in the basal ganglia is reported. A 17-year-old boy was admitted to our hospital on July 30, 1988 because of headache and vomiting, and a right hemiparesis. On admission, physical inspection showed no abnormalities and neurological examination revealed obtunded consciousness, a right central facial paresis and a right hemiparesis with Hoffman and Babinski reflexes. Noncontrast CT scan showed a large mass of low-to slightly high-density in the region of the left basal ganglia accompanied with midline shift and ventricular dilatation. Enhancement of the lesion was made by contrast CT scan. It was not homogeneous. Cerebral angiogram displayed a contralateral shift and an unrolling of the anterior cerebral artery, a lateral stretch of middle cerebral artery, a downward stretch of anterior choroidal artery and a tumor stain fed by the Heubner artery. On August 3, left frontotemporal craniotomy was performed. The tumor was totally removed in a piecemeal manner using microsurgical techniques. Histopathological diagnosis was mixed-type of germ cell tumor comprising embryonal carcinoma and teratoma. Postoperative CT scan showed complete disappearance of the tumor. A course of radiation of 4950 rads and two courses of a combination chemotherapy with cis-platinum, vinblastine and bleomycin were given within 3 months after the operation.(ABSTRACT TRUNCATED AT 250 WORDS)
