外傷性脊髓硬腦膜下腔血腫是一種少見的疾病。顱內蜘蛛網膜囊腫出血伴隨硬腦膜下腔血腫也並不常見。一個二十歲年輕男性在輕微的運動傷害後，於薦椎處發現亞急性硬腦膜下腔血腫。他接受脊髓減壓手術，術後恢復良好。不幸的是，術後一星期突然出現失語症。腦部電腦斷層和磁振造影發現原本的顱內蜘蛛網膜囊腫出現囊內出血伴隨硬腦膜下腔血腫。我們討論兩者之間的關係。
Traumatic spinal subdural hematoma is a rare entity. Hemorrhage of intracranial arachonoid cyst is also uncommon. One 20 year-old man suffered from subacute intraspinal subdural hematoma in the sacral level after minor sports injury. He received spinal surgery for decompression and the symptoms recovered well after operation. Unfortunately, he suffered from sudden onset of aphasia one week later. Intracystic hemorrhage of pre-existing arachnoid cyst with adjacent subdural hematoma was found on CT and MRI of brain. The relation between these two events was discussed.
