Abstract: Wandering spleen (WS), known as the ectopic spleen, was first identified in autopsies by Dutch physician Johannes von home in 1677. It is an acute or chronic disease caused by increased activity of the spleen. When a splenic torsion occurs in the WS, it is called splenic torsion (ST). The incidence of ST is small, accounting for only 20% of WS, but it is extremely dangerous, and severe cases can cause splenic infarction or even life-threatening. The disease is rare, with only 500 cases reported worldwide. There have been no cases of ST with pancreatic tail torsion reported in China. To improve the awareness of the disease, one patient admitted to our hospital was reported.
