顶端闭锁脑膨出(PAC)是一种小的头皮下病变，其下有颅外脑膜、神经和神经胶质组织。在这篇文章中，我们分析了有关PAC相关静脉畸形连续体的相关文献，并报告了一个示范性病例。使用以下搜索算法搜索PubMed Medline数据库：(闭锁脑膨出)OR(不典型脑膜膨出)OR(不典型脑膜膨出)OR(脑膜膨出)OR(脑膜异位畸形)。只有详细描述与PAC相关的静脉畸形的论文才被包括在内。在我们的搜索中，共有30篇文献记录了与PAC相关的静脉异常。报告的病例总数为68例(包括我们的示范病例)。伴发静脉畸形以“上矢状窦开窗”最常见，占48.5%(n=33)，其次为“永存镰状窦”占47%(n=32)，直窦垂直胚胎定位占44%(n=30)。SS完全缺失占39.7%(n=27)，Galen系统各种异常占26.8%(n=12)。尽管PAC本质上是良性的，但它往往是复杂和可变的脑静脉畸形存在的标志，需要对浅静脉和深静脉系统进行广泛的术前影像检查，以准确了解静脉系统的解剖结构，并指导手术计划。
Parietal atretic cephalocele (PAC) is a small, subscalp lesion with underlying extracranial meningeal, neural, and glial tissues. In this paper, we analyze the related literature on the continuum of PAC-associated venous anomalies and report an exemplary case. The PubMed Medline database was searched using the following search algorithm: (Atretic encephalocele) OR (Rudimentary meningocele,) OR (Atypical meningocele) OR (Meningocele manqué) OR (Meningeal heterotopia). Only papers detailing the venous anomalies associated with PACs have been included. A total of 30 papers in our search documented PAC-associated venous abnormalities. The overall number of cases reported was 68 (including our exemplary case). The most frequently identified associated venous anomaly was the presence of a “fenestrated superior sagittal sinus” recorded in 48.5% of cases (n = 33), followed closely by “persistent falcine sinus” in 47% (n = 32) and vertical embryonic positioning of the straight sinus (SS) in 44% (n = 30). The complete absence of a SS was reported in 39.7% (n = 27) and various anomalies of the Galenic system were reported in 26.8% of cases (n = 12). Although benign in nature, PACs are often a marker for the presence of complex and variable cerebral venous malformations, requiring extensive preoperative imaging workup for both the superficial and deep venous systems to obtain an accurate understanding of the anatomy of the venous system and guide surgical planning.
