Torsion of a wandering accessory spleen: CT findings

Abstract

Torsion of an accessory spleen is a rare entity that can have a variable clinical presentation. We report the computed tomographic (CT) findings of an acute torsion of an accessory spleen in a 13-year-old girl. CT disclosed a hypodense mesenteric mass with peripheral inflammatory changes.

Accessory spleen appearing as an intrasplenic pseudo-tumoral mass: A rare case report

“…However, when located at atypical sites, accompanied by other lesions or manifested as corresponding symptoms, it may be confused with pancreatic (7) or left kidney tumors (8). In the current case, the lesion was located inside the proper spleen and presented with a poor boundary with surrounding normal splenic tissues.…”

Enlarged accessory spleen presenting stomach submucosal tumor

“…Based on these findings, an accessory spleen was suspected. Some accessory spleens, however, can mimic an enlarged lymph node as well as a tumor arising from adjacent organs such as the adrenal gland, pancreas and kidney [14][15][16][17] . In fact, differentiation from a hypervascular pancreatic neoplasm (e.g.…”

“…A diagnosis of accessory spleen manifesting as a gastric SMT was made. As complications associated with an accessory spleen can rarely include torsion of a wandering accessory spleen or bleeding caused by spontaneous rupture [14][15][16][17], the patient is now carefully followed in outpatient clinic.…”

“…It is located at the splenic hilum or adjacent to the pancreatic tail in most cases [3,6] . Although it is usually asymptomatic and incidentally discovered, accessory spleen is clinically important in certain patients [7][8][9][10][11][12][13][14][15][16][17] . It is likely that some accessory spleens simulate tumors arising from adjacent organs such as the kidney, adrenal grand and pancreas [3][4][5][6][7][8][9][10] .…”

Diagnosis of an Accessory Spleen Mimicking a Gastric Submucosal Tumor Using Endoscopic Ultrasonography-guided Fine-needle Aspiration

“…1 Accessory spleens have been reported to mimic gastric SMTs, enlarged lymph nodes, and tumors arising from adjacent organs such as the adrenal gland, pancreas, and kidney. [5][6][7][8][9] Although an accessory spleen is an incidental finding with no clinical significance in most patients, 2,10 they can sometimes become symptomatic due to torsion, spontaneous rupture, hemorrhage and cystic formation. [5][6][7][8] Therefore, detection and characterization can be clinically important, especially in cases such as the present one where the lesion mimicked a gastric SMT.…”
