Acute necrotising pancreatitis from ascariasis in a gravid patient.

Rarer causes of acute pancreatitis may be considered in certain settings, such as parasitism in endemic regions. This report describes a pregnant female (second trimester) in her 20s who presented with 3-day steady epigastric pain radiating to the back and passage of worm from the mouth. She was diagnosed with mild acute pancreatitis, given a significantly elevated serum lipase and absence of organ failures. Fecalysis showed Ascaris lumbricoides ova; hence, she was treated with mebendazole. Plain MR cholangiopancreatography showed an 842 mL necrotic pancreatic fluid collection and tubular flow void foci within the gallbladder and duodenum consistent with helminthiasis. The patient was managed conservatively in the absence of indications for drainage. The abdominal pain remarkably improved, and she underwent eventual vacuum-assisted delivery to a healthy term baby 4 months after the bout of acute pancreatitis.
