Infarction of an accessory spleen causing an acute abdomen

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

“…However, an accessory spleen manifesting as a solid intrasplenic pseudotumor has rarely been reported. Previous studies reported an accessory spleen presenting as an inflammatory mass and provided radiologic imaging of splenic abnormalities (2,3,7). In the present study, the case of a male patient who was admitted to The Second Hospital of Shandong University (Jinan, China) presenting with a pseudotumoral accessory spleen is reported.…”

“…An accessory spleen is a normal variant that is typically located at the splenic hilum, but is occasionally noted as a tumor-mimicking lesion located at multiple other sites, including the pelvis or gastrocolic ligament (1), and even the left scrotum (2) or mediastinum (3). Accessory spleens occur in ~10% of the population and are usually located in the region of the splenic helum.…”

Multiple accessory spleens: Case report and literature review

“…An accessory spleen is of no significance per se. Under certain circumstances, however, its presence assumes considerable clinical significance (Babcock et al, 1974;Appel and Bart, 1976;Rosenthal and Bishop, 1981;Rudowski, 1985). Hypertrophy of accessory spleens after splenectomy in patients with hematological disorders (Olsen and Beaudoin, 1969;Schwartz et al, 1971;Hann and Wainscoat, 1976;Rudowski, 1985), as well as progressive enlargement of splenic tissue following autotransplantation due to abdominal trauma (Shaw and Shafi, 1937;Fleming et al, 1960;Doulton et al, 1971), have been previously described.…”

An accessory spleen presenting as a scrota1 mass (Sneath, 1912;Olken, 1945;Bennett-Jones and Hill, 1952) or as a surgical emergency with symptoms of "acute abdomen" (Kitchin and Green, 1962;Patruskev, 1970;Babcock et al, 1974;Texeira and Hardin, 1974) have also been reported.…”

Torsion of Accessory Spleen- A Rare Cause of Acute Abdomen in Pregnancy: A Case Report.

“…Accessory spleen or splenunculi is the most common anomaly of splenic embryology that consists of single or multiple ectopic splenic tissues separated from the main body of the spleen with its own blood supply.The prevalence of accessory spleen is 10-30% in autopsies series, and 3-11% of computed tomography (CT) and ultrasound (US) examinations [1][2][3][4] .…”
