송과체외에 발생한 두개내 배아세포종의 뇌전전산화단층촬영 = Brain CT of Non-Pineal Intracranial Germ Cell Tumors

다국어 초록 (Multilingual Abstract)

19 cases of non-pineal intracranial germ cell tumors were reviewed retrospectively with both radiologic and clinical features. The result were as follows ; 1. The age distribution was 8 to 32 year old (16 year old of mean age) and the sex distribution shows male predominence (15:4). 2. The histopathologic diagnosis includes 11 cases of germinoma, 2 cases of mixed germ cell tumor, 1 case of embryonal cell carcinoma and 5 cases of unknown. 3. The location of tumors was the suprasellar region in 8 cases, the left basal ganglia and thalamus in cases, and the right frontal lobe in 1 case. Among 11 case of germinoma, 6 cases involve the suprasellar region and 3 cases the left basal haglia and thalamus. 4. Inclinical features. there were visual disturbance, diabetes insipidus, increases ICP signs, motor weakness, hormonal disorders, and personal changes in order. 5. in tomor maker study of 6 cases of germinoma, 5 cases show increase in HCG titer, but all 6 cases were normal in AFP iter. 6. In brain Ct, most of all revealed well-defined homogeneous high density with or without small central low density and homogeneous enhancement at solid portion, and there was calcification in only case with mixed germ cell tumor.
