Abstract
Agenesis of the dorsal pancreas is a rare congenital anomaly.
The possibility of finding this disorder is increasing with the use of advanced radiological techniques.
Some patients experience no symptoms.
Rarely, they may also develop pancreatic exocrine insufficiency or pancreatic adenocarcinoma.
This diagnosis could be missed by US, due to difficulty on visualization of body and tail of pancreas.
Introduction
Agenesis of the dorsal pancreas (ADP) is a rare congenital anomaly resulting in missing corpus and cauda of the pancreas. The possibility of finding this disorder is increasing with the use of advanced radiological techniques like CT scan or MRI.
Presentation of case
We reported 2 cases of a partial ADP as radiological finding: the first one was a 79-year-old asymptomatic patient who presented to perform a CT staging scan for bladder tumor, while the second case was a 73-year-old patient with obstructive jaundice and with suspected common bile duct calculi. In the second patient US, CT scan and MRI were performed, and after that also an ERCP was scheduled.
Discussion
The prevalence of agenesis of the dorsal pancreas is not exactly known; in the literature, only 50 cases have been reported. Its cause and pathogenesis are not fully understood. Some patients experience no symptoms, while others may develop hyperglycemia, diabetes mellitus, bile duct obstruction, abdominal pain, pancreatitis, or other conditions.
Conclusion
Considering that dorsal agenesis is sporadically found, often do not have related symptoms and it does not require a specific treatment, whether further examinations are needed to determine the type of agenesis remains questioned.
