45-year-old female presented with abdominal pain.
What is the most likely diagnosis?
Answer
Answer:
Pancreas divisum
Case Discussion:
MRCP revealed the dorsal pancreatic duct being in direct continuity with the duct of Santorini, which drains into the minor ampulla
Pancreas divisum represents a variation in pancreatic ductal anatomy that can be associated with abdominal pain and idiopathic pancreatitis. It is characterised, in the majority of cases, by the dorsal pancreatic duct (main pancreatic and Santorini ducts) directly entering the minor papilla with no communication with the ventral duct (Wirsung), and thus, the major papilla.
