There is marked intra and extra great duct dilatation with the common hepatic duct measuring up to 16 mm in diameter. The pancreatic duct is also dilated measuring approximately 7 mm at the pancreatic head. No obstructing lesion is identified within the ampulla on dedicated MRCP imaging. On unenhanced sequences, there is no lesion within the pancreatic head. The pancreatic duct distally is dilated without regions of stricturing. Small T2 hyperintense lesions within the pancreatic tail appear continuous with the pancreatic duct and likely represent small IPMN measuring 12mm. No focal hepatic lesion identified. The remaining imaged upper abdominal organs are unremarkable. Possible posterior basal left lower lobe 6 mm nodule.
Conclusion: Marked intra and extra hepatic duct dilatation as well as enlargement of the pancreatic duct. An obstructing calculus is seen in the common channel created by the CBD and pancreatic duct. Possible left lower lobe 6 mm lung nodule can be further characterised with CT. 7 cm pelvic mass could be confirmed as a fibroid uterus with US if required.
