Abstract

The spleen, an accessory organ located within the pancreatic parenchyma, is a congenital anomaly of the splenic tissue with morphological and histological characteristics resembling to a normal spleen, usually in the tail of the pancreas. The intra-pancreatic accessory spleen (IPAS) is mainly a benign lesion, being usually asymptomatic and found on imaging studies on an incidental basis, but which often raises concern about malignancy and may be radiographically indistinguishable from neuroendocrine tumours, pandreatic tumours and adenocarcinomas. Therefore, the present study aims to report a case of IPAS by using computed tomography (CT) and magnetic resonance (MR) imaging, in addition to correlating the radiographic findings of the case report with other radiological methods in the literature review. Information was obtained by reviewing medical records, conducting interviews with the patient and using diagnostic photographs as well as laboratory data. In this context, the case report is of a male patient with previous history renal cell carcinoma and who had undergone total left nephrectomy and resection of retroperitoneal lymph nodes. Post-operative followed-up exams showed a nodular image in the pancreatic tail suggestive of metastasis, but whose correct diagnosis was possible by means of CT and MR studies as only an asymptomatic benign affection was shown, meaning that only a conservative intervention was necessary.
