摘要

Von Meyenburg复合体是一种良性胆管错构瘤,表现为肝脏囊性结节。Von Meyenburg复合体通常是无症状的,因此通常在成像或尸检时偶然发现。它们也可以在手术时遇到,它们通常表现为分散的白色肝脏病变,与恶性肿瘤有关。在此,我们报告一位36岁女性在腹腔镜胆囊切除术中偶然发现白色肝结节的病例。病理分析证实了von Meyenburg复合物的诊断。手术医生继续进行腹腔镜胆囊切除术,无并发症。我们报告这个病例是为了鼓励人们对这种良性实体的认识。术中发现的分散的肝脏病变可以引起对转移性肿瘤进程的关注。了解von Meyenburg复合物及其大体外观可以更好地指导外科医生在遇到这些特征性肝脏病变时的术中决策。

Benign Finding or Malignancy: von Meyenburg Complexes Found during Laparoscopic Cholecystectomy.

Von Meyenburg complexes are benign bile duct hamartomas that arise as cystic nodules of the liver. Von Meyenburg complexes are often asymptomatic and thus typically discovered incidentally on imaging or autopsy. They can also be encountered at the time of surgery where they often appear as scattered white liver lesions concerning for malignancy. Here, we present a case in which white hepatic nodules were found incidentally during laparoscopic cholecystectomy in a 36 -year-old female. Pathologic analysis confirmed the diagnosis of von Meyenburg complexes. The operating surgeon proceeded with laparoscopic cholecystectomy without complication. We report this case to encourage awareness of this benign entity. The finding of scattered hepatic lesions found intra-operatively can create concern for metastatic neoplastic processes. An awareness of von Meyenburg complexes and their gross appearance can better guide surgeons' intraoperative decision-making when encountering these characteristic hepatic lesions.
