Axial sections of CT scan when the patient first presented to our hospital, showing an important infiltration of the left perirenal and pararenal fat with the presence of a collection of upper pole of the left kidney, which measured 25 × 40 mm and had a liquid density. The collection presented peripheral rim enhancement and the pancreas was within normal size without swelling. The CT also revealed a pancreatic pseudocyst of 68 × 50 mm, which was associated with a discreet dilation of the Wirsung canal
