Coexisting giant splenic artery aneurysm and non-functioning pancreatic neuroendocrine tumor

The splenic artery aneurysm (SAA) is rare clinical entity which is the third most common intra-abdominal aneurysm. Pancreatic neuroendocrine tumors (pNETs) are rare malignancies which comprise less than 2% of all pancreatic tumors. Non-functioning pancreatic neuroendocrine tumors set forth up to 90% of all PNETs. Sixty-seven-year-old female presented to our polyclinic with increasing pain in the left upper quadrant in the previous three months. A computed tomographic angiography revealed 13x13x12 cm sized regular bounded aneurysmatic expansion of medium part of splenic artery. In addition there was a 8x7 mm sized hypoecoic lesion in the distal pancreatic tissue. Distal pancreatectomy, splenic aneurysm resection and splenectomy was performed. Pathological results revealed that there was a 12 cm sized giant true splenic aneurysm and 0.7 cm sized neuroendocrine tumor in the pancreatic tissue. This manuscript is presentation of surgical approach to a case with coexistence of these two rare conditions.
