CTICasesPancreatic Pseudocyst Extending into Thoracic Inlet

Imaging findings
The patient had a history of gallstone pancreatitis, cholecystectomy, and ERCP, complicated by abdominal pseudocysts and a left pleural effusion. A CT performed for substernal pain revealed a complex fluid collection originating from the pancreatic bed, extending superiorly through the diaphragmatic hiatus. This collection encircled the esophagus and continued superiorly, reaching the thoracic inlet. It appeared to parallel the esophageal wall rather than being within it, pushing the esophagus aside.
Key takeaways
This case presented a remarkably long, continuous pancreatic pseudocyst extending from the pancreatic bed all the way to the thoracic inlet, mimicking a 'pseudoesophagus'. This extensive involvement is an unusual complication of pancreatitis. Conservative management was planned due to the complexity of draining such a long and tortuous collection.
