Résumé
Pancreatic pseudocyst is a common complication of acute/chronic pancreatitis, but extension of a pancreatic pseudocyst into the mediastinum is a rare occurrence. In this report, we described a case of a 62-year-old male with necrotizing pancreatitis presenting with chest pain and dysphagia caused by a mediastinal pseudocyst. Endoscopic retrograde pancreatography revealed pancreatic duct disruption and leaks. A mediastinal pseudocyst was successfully drained by endoscopic ultrasound (EUS)-guided transesophageal approach. Chest pain and dysphagia disappeared swiftly with drainage. Associated pancreatic pseudocyst at tail was managed by EUS-guided cystogastrostomy and pleural effusion was controlled by percutaneous drainage, respectively. In a follow-up period of 3 months, there has been no recurrence of symptoms and signs. Although currently EUS-guided transesophageal approach was done in the selected cases, this procedure is technically feasible, less invasive and more effective than surgical approach.
