Brain arachnoid cysts are fluid collections of developmental origin. They are commonly detected incidentally in patients imaged for unrelated symptoms.
A 15-year-old healthy boy with a recent history of head trauma experienced headache that gradually worsened over the course of 10 days. He underwent CT and MRI brain scans which revealed the presence of subdural haematoma caused by the rupture of a middle cranial fossa arachnoid cyst. This was accompanied by intracystic haemorrhage. The subdural haematoma was removed, while communication of the cyst with the basal cisterns was also performed. The postoperative course of the patient was uneventful.
The annual haemorrhage risk for the patients with middle cranial fossa cysts remains very low. However, when haemorrhage occurs, in most occasions it can be effectively managed only with haematoma evacuation.
脑蛛网膜囊肿是起源于发育过程的液体积聚。它们通常在因无关症状进行成像检查的患者中偶然被发现。
一名15岁健康男孩近期有头部外伤史，经历了头痛，在10天内逐渐加重。他接受了脑部CT和MRI扫描，结果显示中颅窝蛛网膜囊肿破裂导致硬膜下血肿，并伴有囊内出血。硬膜下血肿被清除，同时囊肿与基底池之间也进行了沟通。患者术后恢复顺利。
中颅窝囊肿患者每年的出血风险仍然很低。然而，当出血发生时，在大多数情况下，仅通过血肿清除才能有效处理。
