A rare complication of radical nephrectomy: a pancreatic pseudocyst

A 48-year-old woman presented with a painless mass inthe left kidney, discovered incidentally during abdominalultrasonography. The renal tumour was removed via ananterior abdominal approach. After radical nephrectomythere were no early complications. Histological examina-tion revealed stage II RCC (Robson classiﬁcation). At the3-month follow-up she presented with left ﬂank pain. Adetailed evaluation included CT and MRI, which showeda large cystic mass overlying the operated renal fossa(Fig. 1). The left ﬂank was explored to clarify the nature ofthe mass. A pancreatic pseudocyst was diagnosed aftersurgery, the key to the diagnosis being the high amylasecontent of the ﬂuid collected during the surgical interven-tion. Treatment comprised the administration of soma-tostatin (0.2 mg daily) for 2 weeks. Spontaneous closureoccurred on the 15th day of therapy and an additionalsurgical procedure was not required.
