Absence of the falx cerebri is a rare radiological finding, which is generally described in relation with varying degrees of holoprosencephaly or other structural central nervous system anomalies. We present a case of non-syndromic, asymptomatic absence of falx cerebri in an elderly patient, which was discovered incidentally on a computed tomography examination of the head. The superior sagittal sinus was narrowed, but present. Relevant anatomic and embryological considerations are discussed, as well as potential implications for clinical practice.
大脑镰缺如是一种罕见的影像学表现，通常与不同程度的前脑无裂畸形或其他中枢神经系统结构异常相关。我们报告一例老年患者非综合征性、无症状的大脑镰缺如病例，该病例在头部计算机断层扫描检查时偶然发现。上矢状窦变窄，但仍然存在。文中讨论了相关的解剖学和胚胎学因素，以及对临床实践的潜在影响。
