We report a rare case of germinoma mainly located in the septum pellucidum.
A 19-year-old man presented with germinoma located in the septum pellucidum manifesting as amnesia and right hemiparesis. Magnetic resonance imaging demonstrated a heterogeneously enhanced mass in the septum pellucidum and abnormal T2-weighted signals in the left basal ganglia. An anterior transcallosal approach was performed to remove the mass in the septum pellucidum. The histological diagnosis was germinoma. Radiotherapy and chemotherapy were given. He was discharged with slight amnesia and right hemipareis.
Intracranial germinoma can arise from the septum pellucidum.
我们报告一例罕见的主要位于透明隔的生殖细胞瘤。
一名19岁男性，患有位于透明隔的生殖细胞瘤，表现为失忆和右侧偏瘫。磁共振成像显示透明隔有不均匀强化肿块，左侧基底节区T2加权信号异常。采用经胼胝体前入路切除透明隔内的肿块。组织学诊断为生殖细胞瘤。给予放疗和化疗。患者出院时仍有轻微失忆和右侧偏瘫。
颅内生殖细胞瘤可起源于透明隔。
