One of the standard surgical approaches to lateral ventricular tumors involves interhemispheric dissection along the falx cerebri. The falx cerebri thus provides an important landmark in guiding the surgeon to the midline. Unrecognized absence of falx may lead to surgical complications. A child with tuberous sclerosis presented with refractory epilepsy and a lateral ventricular tumor. The tumor was excised by an interhemispheric trans-callosal approach. The midline falx cerebri was absent anteriorly, rendering the identification of midline difficult. The embryology of a deficient falx and its surgical implications are discussed in this short report.
外侧脑室肿瘤的标准手术入路之一是沿大脑镰进行半球间分离。因此，大脑镰是引导外科医生到达中线的重要标志。未识别出大脑镰缺失可能会导致手术并发症。一名患有结节性硬化症的儿童出现难治性癫痫和外侧脑室肿瘤。通过半球间经胼胝体入路切除了肿瘤。中线大脑镰前部缺失，使得中线的识别变得困难。本简短报告讨论了大脑镰发育不全的胚胎学及其手术意义。
