Cystic lesions of the liver are commonly encountered in routine clinical practice with a reported prevalence of 15%-18%. They may range from a benign simple developmental cyst to a malignancy. Therefore, an accurate diagnosis is essential for adequate management. Cystic tumors of the liver are classified based on the content (mucin containing or not), presence of ovarian stroma, and biliary communication. Biliary cystadenoma are a group of hepatobiliary neoplasia which by definition must be multilocular, lined by a columnar epithelium, and have a densely cellular ovarian stroma. We report a case of a cystic lesion in the hilar region of the liver, which had features of biliary cystadenoma on the preoperative imaging. However, on exploration was found to be a diverticular variant of type V choledochal cyst arising from both hepatic ducts. We have discussed the preoperative imaging features, intraoperative cholangiogram, and the management of this cystic lesion.

Article Synopsis
- Choledochal cysts are congenital bile duct abnormalities classified into five main types, with this case focusing on an intrahepatic variant mistaken for biliary cystadenoma.
- A 35-year-old woman experienced pain and a palpable mass, leading to diagnostic imaging that revealed a complicated cyst affecting her liver's bile ducts.
- Surgical intervention was required due to the cyst's complexity, and while the gallbladder was removed, the cyst could not be entirely separated from the common hepatic duct, highlighting the need for careful evaluation to prevent complications.

Biliary cystadenomas are uncommon lesions with clinical and radiological characteristics that overlap with other cystic liver lesions. Here, we intended to discuss a biliary cystadenoma found in a 37-year-old female patient who had been treated for a liver abscess and had been sent to our clinic with a long-term hydatid cyst diagnosis.

Article Synopsis
- Mucinous cystic neoplasms of the liver (MCN-L) are typically benign and asymptomatic.
- Rarely, MCN-L can lead to serious complications like jaundice and acute abdominal pain, sometimes due to cyst prolapse or rupture.
- A case is presented where a patient with MCN-L experienced these complications, but surgical treatment resulted in successful management and normal follow-up imaging.

The recently published WHO Reporting System for Pancreaticobiliary Cytopathology (World Health Organization [WHO] System) is an international approach to the standardized reporting of pancreaticobiliary cytopathology, updating the Papanicolaou Society of Cytopathology System for Reporting Pancreaticobiliary Cytology (PSC System). Significant changes were made to the categorization of benign neoplasms, intraductal neoplasms, mucinous cystic neoplasms, and malignant neoplasms considered low grade. Benign neoplasms, such as serous cystadenoma, categorized as Neoplastic: benign in the PSC system, are categorized as Benign/negative for malignancy in the WHO system.
