A 27-year-old male with a history of heavy alcohol use presents with progressive abdominal distension following an episode of acute pancreatitis. A contrast-enhanced CT scan of the abdomen showed a large multilocular cystic lesion almost occupying the entire abdominal cavity and displacing the liver medially and the right dome of the diaphragm superiorly. The largest locule on the right side measured 30 cm × 15 cm × 14 cm. Ultrasound-guided drainage of the cyst was performed. The cyst was entered into with a lumen-opposing metal stent deployed under fluoroscopic vision, followed by dilatation with a 10 mm controlled radial expansion balloon. A repeat ultrasound was done a week later due to the persistence of the collection, and a second stent was inserted. Then, 10 French gauge × 10 cm double-ended pigtails were inserted through both stents. The cysts were not visualized on subsequent Ultrasound scans. Stent removal was done after 3 weeks, leaving the pigtails in situ. The patient made an uneventful recovery.
