A Rare Complication of Atypical Pancreatic Pseudocysts: A Case of Psoas Abscess with Renal Abscess

Abstract

Pancreatic pseudocysts can extend beyond the boundaries of the pancreas due to the enzymatic nature of the fluid they contain. However, the extension of a pseudocyst beyond the retroperitoneum, into the psoas muscle, and within the subcapsular space of the left kidney is extremely rare, with only a few documented cases in the medical literature. In this report, authors present a case of a 36-year-old male with chronic pancreatitis and atypical pseudocysts that were left untreated due to his negligence. Secondary infection led to the formation of a psoas abscess, perinephric abscess, and a renal abscess. Complications such as intracystic haemorrhage, infection, and rupture of a pseudocyst are uncommon and can be fatal, if treatment is delayed. Pseudocysts in atypical locations, complicated by a secondary infection, are extremely rare and must be timely and effectively managed.
