“…10 These lesions have also been identified during laparoscopic procedures. [11][12][13][14][15] They typically appear as numerous white scattered lesions, which can be disconcerting to the operating surgeon given the similar appearance of diffuse liver metastases. It is for this reason that we believe it to be important that surgeons are aware of this rare diagnosis and this potential red herring during surgery.…”

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 36year-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.
