TWO CLINICAL CASES OF ACCESSORY SPLEEN LOBE IN PANCREATIC TISSUE

Abstract

An additional spleen, occurring with a frequency of 10-30%, is usually detected accidentally during instrumental studies of the abdominal cavity and rarely causes clinical symptoms. In two clinical cases described in this article, an accessory spleen localized in the tail of the pancreas mimicked a neuroendocrine tumor, which led to laparoscopic splenoservative caudal resection of the pancreas. Histological examination confirmed the presence of an additional spleen. These cases emphasize the importance of differential diagnosis, since the accessory spleen performs all the functions of the main spleen and its presence does not require surgical intervention. Imaging techniques such as PET/CT with 68Ga-DOTA-TOC and scintigraphy with labeled erythrocytes can significantly improve the accuracy of diagnosis and help distinguish between the accessory spleen and neuroendocrine tumors of the pancreas, thereby reducing the risk of unnecessary operations. However, these research methods were not available, so the decision on surgical treatment was made on the basis of CT with contrast.
