We present a case of obstructive acute pancreatitis due to infestation with ascaris worm in a very young child. The child had an acute abdominal presentation. The investigations showed high serum amylase; the CT scan showed a hypoechoic tubular shadow in the jejunum with evidence for severe pancreatic necrosis. The child was managed conservatively, and received anthelmintic medication. She passed the worm in the stool and recovered completely.
