颅内生殖细胞瘤好发于松果体区及鞍上区,发生于基底节丘脑区者约占5％～10％。有关基底节丘脑区生殖细胞瘤的CT、MRI的报道甚少,作者报道3例,并探讨CT、MRI的诊断价值。3例患者均为经组织学确诊的男性患者,年龄8～11岁,且松果体区无肿瘤,血清及脑脊液AFP、βHCG正常。CT及MRI显示1例为囊性肿瘤,2例为实质性肿瘤。肿瘤实质和囊壁的MRI无特异性,T_1WI为等信号
Intracranial germinoma occurs in the pineal region and the suprasellar region, occurring in the basal ganglia area accounts for about 5% to 10%. The basal ganglia germ cell tumors of the CT, MRI rarely reported, the authors reported in 3 cases, and to explore the diagnostic value of CT, MRI. All 3 patients were histologically confirmed male patients, aged 8 to 11 years old. There were no tumor in the pineal region, normal serum and cerebrospinal fluid AFP and βHCG. CT and MRI showed cystic tumor in 1 case and solid tumor in 2 cases. The tumor parenchyma and non-specific MRI of the wall, T_1WI is equal signal
