Most of them are innocent until found. Lately, there have been a few case reports of intrapancreatic spleen misdiagnosis leading to unnecessary pancreatic surgery. We report the case of a 64-year-old woman who had a hypervascular pancreatic nodule diagnosed on dynamic CT and MRI after an episode of acute pancreatitis. The patient's progress was followed for 18\u2005months, repeated the CT and MRI examinations and an endoscopic ultrasonography with fine needle aspiration was performed. Neoplastic cells were not identified on cytology. Despite the stability of the lesion, \u00a0a distal pancreatectomy was performed to exclude a neuroendocrinal tumour. An intrapancreatic accessory spleen was ultimately identified on histological examination.<\/jats:p>","DOI":"10.1136\/bcr-2012-008471","type":"journal-article","created":{"date-parts":[[2013,2,6]],"date-time":"2013-02-06T00:29:37Z","timestamp":1360110577000},"page":"bcr2012008471","source":"Crossref","is-referenced-by-count":6,"title":["Intrapancreatic
