Intraductal Papillary Neoplasm of the Bile Duct: Radiological Diagnosis of a Rare Entity: Case Series.

BACKGROUND

Intraductal papillary neoplasm of the bile duct (IPNB) is a rare bile duct neoplasm characterized by an intraluminal papillary growth pattern in bile ducts and is considered a biliary counterpart of intraductal papillary mucinous neoplasm of the pancreas.

CASE DESCRIPTION: We report here two cases. (1) A case of a 34-year-old woman who presented with complaints of pain in the abdomen, jaundice, and pruritus. Further radiological investigations revealed the possibility of an IPNB, which was confirmed on histopathology. (2) A case of a 61-year-old man who was a known case of Barrett's esophagus and presented with complaints of right upper abdomen and jaundice. Radiological investigations and histopathology further confirmed the diagnosis of an IPNB involving the extrahepatic bile ducts. The purpose of this article is to highlight the role of computed tomography (CT) and magnetic resonance imaging in reaching this challenging diagnosis.

CONCLUSION

Although the diagnosis is not straightforward, imaging plays a great role in raising the possibility of an IPNB. The correct preoperative diagnosis is necessary for accurate surgical planning and resection.
