摘要


顱內蜘蛛膜囊腫被視為是先天的問題,偶爾會在小孩身上發現但並不伴隨任何的症狀。慢性硬腦膜下血腫通常發生在老年的病人,病史中包含了在症狀出現的幾個月前曾有過輕微的頭部外傷。然而,這兩種在臨床上截然不同的疾病卻偶爾會出現在同一個年輕的病人身上。我們報告一個29歲男性,他在過去三個月內不斷出現頭痛和暈眩的症狀。我們給病人做的腦部電腦斷層掃描卻發現其左額-頂葉有一巨大的慢性硬腦膜下血腫,且意外的發現在同一側的希氏裂出現一個蜘蛛膜囊腫。蜘蛛膜囊腫可視為造成慢性硬膜下血腫的危險因子,我們針對此一罕見疾病做一文獻回顧及探討。

並列摘要


Intracranial arachnoid cysts are believed to be congenital; they can become symptomatic in pediatric patients. Chronic subdural hematomas tend to occur in elderly patients with a history of mild head injury a few months prior to the onset of symptoms. However, these two distinct clinical entities sporadically occur together in relatively young patients. We report a 29-year-old man who presented with headache and dizziness of 2 months' duration. Brain computed tomography revealed a huge chronic subdural hematoma over the left frontoparietal lobe, with an incidental finding of an arachnoid cyst over the left sylvian fissure. In light of a literature review, we discuss arachnoid cysts as a possible risk factor for subdural hematoma, especially in young adults.
