The authors describe the case of a 37-year-old patient, who, after a minor craniocerebral trauma suffered in 1970, was admitted to hospital because of progressive headache, unsteady gait and balance disturbances, deglutition disorders and diplopia. Computed tomography (CT) scan showed a large median hyperdense tumour of posterior fossa with the fourth ventricle involvement. Operation under microscope was performed to remove a considerably large cystic tumour, occupying the fourth ventricle and cisterna magna, displacing the cerebellar lobes and pushing the vermis upward. The tumour was waxy and grey, whereas the cystic liquid had the colour and consistency of oily fluid. The capsule was occluded with the CO2 laser. Postoperative course was good.
作者描述了一名37岁患者的病例，该患者在1970年遭受轻微颅脑创伤后，因进行性头痛、步态不稳和平衡障碍、吞咽障碍及复视而入院。计算机断层扫描（CT）显示后颅窝有一个巨大的中线高密度肿瘤，累及第四脑室。在显微镜下进行手术，切除了一个相当大的囊性肿瘤，该肿瘤占据第四脑室和小脑延髓池，使小脑叶移位并将蚓部向上推。肿瘤呈蜡样且为灰色，而囊液具有油性液体的颜色和稠度。用二氧化碳激光封闭包膜。术后病程顺利。
