Pancreatic incidentalomas: a growing clinical challenge exemplified by an intrapancreatic accessory spleen.

In part owing to an increasing use of high resolution imaging technologies a growing number of incidental pancreatic lesions are detected. A 40-year-old patient was admitted to our hospital to undergo resection for an unclear solid pancreatic tumor in the pancreatic tail. Preoperative imaging studies suspected an inactive neuroendocrine neoplasm. After distal pancreatectomy, the histopathological analysis revealed an intrapancreatic accessory spleen. Since reliable biomarkers are not established the clinical management of pancreatic incidentalomas is still challenging.
