Arachnoid cysts of the middle cerebral fossa is a not uncommon lesion which can occur in young subjects, sometimes after minimal head trauma. Subdural hematomas and sometimes intracystic hemorrhage may develop. We report a personal series of seven cases seen in young subjects (6-24 years). Clinical presentation was not specific, the complication usually being revealed by signs of intracranial hypertension. The pathogenesis of subdural hematoma is discussed. Magnetic resonance imaging is the most useful diagnostic tool, providing excellent tissue specificity, although CT scan is often used to visualize a subdural hematoma and subsequent arachnoid cyst. Treatment relies on surgery to empty the subdural hematoma and remove compression. There has been no real consensus on treatment modalities. Long-term prognosis is good in most cases.
大脑中窝蛛网膜囊肿是一种并不罕见的病变，可发生于年轻人，有时在轻微头部外伤后出现。可能会形成硬膜下血肿，有时还会发生囊内出血。我们报告了一组在年轻人（6至24岁）中见到的7例病例。临床表现不具特异性，并发症通常由颅内高压症状揭示。本文讨论了硬膜下血肿的发病机制。磁共振成像（MRI）是最有用的诊断工具，具有出色的组织特异性，尽管计算机断层扫描（CT）常被用于显示硬膜下血肿及随后的蛛网膜囊肿。治疗依赖手术来清除硬膜下血肿并解除压迫。对于治疗方式尚未达成真正的共识。大多数病例的长期预后良好。
