颅内囊状动脉瘤是引起成人蛛网膜下腔出血(SAH)的最常见原因,相反,儿童发生 SAH 者少见,其基本病变则常是脑瘤。作者回顾某医院1958～1979年中16岁以下儿童患脑瘤和发生自发性 SAH 者的病历记载,发现患颅内肿瘤的110名儿童中有4例(3.6%)发生典型的 SAH,而在同期发生 SAH 的15例儿童中有动静脉畸形3例(20%),动脉瘤5例(3.4%),脑瘤4例(26%),3例(20%)原因不明。本组病例中最常见的肿瘤(3例)部位与第三脑室有关,且其最常见的病理肿瘤性质是胶质母细胞瘤(2例)。上述说明脑瘤是儿童 SAH 较常见的原因
Intracranial saccular aneurysm is the most common cause of subarachnoid hemorrhage (SAH) in adults. On the contrary, children with SAH are rare, and their basic lesions are often brain tumors. The authors reviewed the medical history of a patient suffering from brain tumors and spontaneous SAH in a hospital from 1958 to 1979. It was found that 4 out of 110 children with intracranial tumors (3.6%) developed typical SAH. Among the 15 children who developed SAH in the same period, 3 had arteriovenous malformations (20%), 5 had aneurysms (3.4%), 4 had brain tumors (26%), and 3 (20%) had unclear reasons. The most common tumor in this group (3 cases) was associated with the third ventricle, and its most common pathological tumor was glioblastoma (2 cases). The above shows that brain tumors are the more common cause of children’s SAH
