Posterior fossa hygroma is a rare entity. In a series of 553 cases of surgically treated traumatic subdural lesions, reported by Jamieson and Yelland, only 14 were in the posterior fossa; of these 7 were hygromas and 7 haematomas, giving an incidence of only 1,4% of all subdural haematomas. This report describes a case of a posterior fossa hygroma, that occurred in a 16-years-old boy, 4 days after an occipital head injury.
后颅窝蛛网膜囊肿是一种罕见的病症。在Jamieson和Yelland报告的553例接受手术治疗的外伤性硬膜下病变病例中，只有14例位于后颅窝；其中7例为蛛网膜囊肿，7例为血肿，在所有硬膜下血肿中所占比例仅为1.4%。本报告描述了一例后颅窝蛛网膜囊肿病例，该病例发生在一名16岁男孩身上，于枕部头部受伤4天后出现。
