A unique case of retroperitoneal abscess of pancreatic origin

Abstract

Retroperitoneal abscesses, though uncommon, present significant diagnostic and therapeutic challenges due to their subtle clinical manifestations. This case report describes a 49-year-old male patient, a chronic alcoholic, presenting with abdominal pain primarily in the right hemiabdomen, alongside a history of pancreatitis. Diagnostic imaging, including ultrasound and CECT scans, revealed a septated abscess originating in the pancreas and extending into the retroperitoneal space. The patient underwent exploration and debridement, with subsequent lab findings indicating elevated amylase and lipase levels, confirming the pancreatic origin of the abscess. Drain placement facilitated abscess resolution. The patient was followed up after 7 days, showing significant improvement, leading to drain removal. This case underscores the importance of early identification and management of retroperitoneal abscesses, particularly those with pancreatic involvement.
