"T2: linear filling defect with associated pancreatic duct dilation 5"
"Ascariasis is due to infection by the human roundworm, Ascaris lumbricoides. Single or multiple worms may be involved. Invasion and subsequent blockage of the distal biliary tree, and less commonly the pancreatic duct, by the helminth causes obstruction to pancreatic enzyme outflow and pancreatic injury 2."

"Intravenous fluids, analgesia and bowel rest is recommended in the acute treatment followed by antihelminth treatment 5. Endoscopic extraction of the worms, or surgery if this fails, can also be used. Dead or fragmented worms can potentially serve as a nidus for future stone formation or could contribute to recurrent pancreatitis so removal is important 5."
