Preoperative differential diagnosis of interhemispheric cysts is sometimes difficult.
We recently experienced a case of symptomatic interhemispheric arachnoid cyst in a 62-year-old woman. We reviewed interhemispheric arachnoid cysts in the elderly and the management of symptomatic interhemispheric arachnoid cysts in elderly patients. Symptomatic interhemispheric arachnoid cysts in the elderly are predominantly located on the right side, have a long history of progressive symptomology, occur predominantly in females, and have no communication with the subarachnoid space. Interhemispheric arachnoid cysts are usually not associated with agenesis of the corpus callosum in elderly patients, whereas interhemispheric nonarachnoid cysts are usually associated with agenesis of the corpus callosum, which will be clearly demonstrated on magnetic resonance imaging.
It is highly possible that an interhemispheric cyst without agenesis of the corpus callosum in an adult is an arachnoid cyst.
大脑半球间囊肿的术前鉴别诊断有时很困难。
我们最近遇到一例62岁女性有症状的大脑半球间蛛网膜囊肿。我们回顾了老年人大脑半球间蛛网膜囊肿以及老年有症状大脑半球间蛛网膜囊肿的治疗。老年有症状大脑半球间蛛网膜囊肿主要位于右侧，有长期渐进性症状史，主要发生于女性，且与蛛网膜下腔无交通。大脑半球间蛛网膜囊肿在老年患者中通常与胼胝体发育不全无关，而大脑半球间非蛛网膜囊肿通常与胼胝体发育不全有关，这在磁共振成像上会清晰显示。
成人中无胼胝体发育不全的大脑半球间囊肿很可能是蛛网膜囊肿。
