The pathophysiology of primary arachnoid cysts of the middle cranial fossa is still unclear, and no widely accepted therapeutic criteria for this condition have been established. The authors present the case of a 7-year-old boy with this cyst accompanied by temporal lobe hypoplasia. On the basis of computerized tomography taken on the 2nd day after birth and magnetic resonance imaging upon admission, the arachnoid cyst in this case was attributed to brain hypoplasia secondary to abnormal arachnoid development and was confirmed to have developed primarily during infancy. Experience with this case yielded new findings useful in clarifying the pathophysiology of this condition and establishing therapeutic criteria for such a case.
中颅窝原发性蛛网膜囊肿的病理生理学仍不清楚，尚未建立针对这种情况的广泛接受的治疗标准。作者报告了一例7岁男孩患有这种囊肿并伴有颞叶发育不全的病例。根据出生后第2天的计算机断层扫描和入院时的磁共振成像，该病例中的蛛网膜囊肿归因于蛛网膜发育异常继发的脑发育不全，并被证实在婴儿期主要就已形成。该病例的经验产生了有助于阐明这种情况的病理生理学并为此类病例建立治疗标准的新发现。
