3 METHODS (DIFFERENTIAL DIAGNOSIS, INVESTIGATIONS, AND TREATMENT)
Contrast-enhanced CT examination of the abdomen and pelvis showed features of chronic pancreatitis and a large perinephric pseudocyst which was communicating with a dilated pancreatic duct in the region of pancreatic tail (Figure 1). This was causing gross compression and displacement of the left kidney posteromedially and inferiorly with resultant splaying and significant thinning of the renal parenchyma (Figure 2).
Subsequently, exploratory laparotomy and cystojejunostomy were done in which more than two liters of turbid-appearing fluid were suctioned. The wall of the cyst was sent for histopathology. Microscopic examination showed fibro-collagenous tissue with a lymphocytic population in a densely fibrosed background. No epithelial lining was seen in the entirely submitted cyst wall, confirming the diagnosis of a pseudocyst (Figure 3).
