Compression of cystic duct caused by focal nodular hyperplasia.J Surg Case Rep 2019; 2019(10):rjz254JS
A 29-year-old female presenting with symptoms of biliary colic was found to have a liver mass compressing the cystic duct. Due to the anatomical placement of the growth, the compressed duct produced symptoms mimicking acute cholecystitis. The mass was diagnosed as focal nodular hyperplasia (FNH) upon biopsy. FNH is commonly found incidentally with nonhepatic clinical presentation or during an unrelated surgical procedure. The scope of this paper is to bring awareness to uncommon causes of biliary colic. To our knowledge, there has been one other paper published with FNH being the primary cause of biliary colic.
