An extremely rare case of a gastric accessory spleen: case report and review of the literature

Abstract

Background The accessory spleen has no anatomical or vascular relationship with the normal spleen, The tissue structure and physiological function of the accessory spleen are the same as those of the normal spleen, which usually locate in the splenic hilum and the tail of the pancreas. The aims of this manuscript are to present a rare case of the gastric accessory spleen and a review of the literature. Case presentation A 19-year-old male patient was sent to the emergency department with stomach bleeding after drinking alcohol. The computed tomographic scan showed a 1.2 cm × 1.7 cm mass at the lesser curvature of the gastric fundus. Gastrointestinal endoscopy displayed a submucosal elevated lesion on the gastric fundus, and gastrectomy was performed. Postoperative pathological examination proved an accessory spleen in the stomach. The postoperative course was uneventful, and the patient was discharged on the 6th day after the surgery. Conclusions The accessory spleen at the fundus of stomach is extremely rare, especially in this case, which is accompanied by acute gastric bleeding, and it is difficult to diagnosis before operation. Many literatures reported that it was misdiagnosis as tumor, so it is necessary to diagnose accessory spleen correctly.

Rare case of upper gastrointestinal hemorrhage due to accessory spleen: A case report

“…[13] While postoperative histopathologic examination is still the gold standard, fine magnetic resonance imaging and enhanced computed tomography scans may be useful in accessory spleen diagnosis. [14] In the present case, the accessory spleen proliferated spontaneously in the presence of the normal spleen, and the cause was unknown. This was likely the cause of severe anemia in the patient 3 years prior to the study, or anemia was the cause of splenomegaly.…”

A Giant Urachal Accessory Spleen: Case Report

“…The attenuation and enhancing characteristics of AS are consistent with the normal spleen on CT images. AS on CT plain scan displays a round or roundish soft tissue lesion of varying sizes, both well circumscribed, appearing as 1-3 cm in diameter, and lesion larger than 4 cm is very rare [4]. Enhanced CT in arterial phase shows flower-spot-like enhancement as a result of the distribution of red and white pulp.…”

EUS-Guided Diagnosis of Gastric Subepithelial Lesions, What Is New?

“…When evaluating a gastric subepithelial lesion, endoscopists need to firstly differentiate if the lesion is intra- or extramural. Common structures that can cause an extrinsic compression are the xyphoid bone (fundus), the left hepatic lobe, spleen/accessory spleen (fundus, upper body), the gallbladder (antrum), or pathologic abdominal masses (such as tumors, pancreatic pseudocysts, enlarged lymph nodes) and vessel aneurysms [ 2 , 7 , 8 ]. Endoscopists can achieve a 92% sensitivity of recognizing extrinsic compressions using EUS [ 9 ].…”
