The clinical entity 'Wandering spleen' is an uncommon presentation and it is more often diagnosed in children than in adults, mostly women of reproductive age. Here is a case of a young woman who presented with generalized weakness and fever, and a painless mobile lump in her central abdomen. The laboratory evaluation revealed a haemolytic state and Haemoglobin electrophoresis showed β-Thalassemia trait (Hb A2 5.1%). Ultrasonography and Computerized Tomography (CT) scan confirmed that the mass is spleen and spleen is not present in its normal anatomical location. Abdominal CT described a well-defined, homogenous pediculated mass with echo texture comparable to spleen. Radioisotope scanning could be used as an alternative for confirmation of diagnosis of this rare condition, but was not done in our case. Colour Doppler sonography of the splenic circulation revealed no infarction and intact splenic vasculature. Wandering spleen should be considered in the differential diagnosis of idiopathic abdominal or pelvic lumps. The authoritative opinion for the treatment of such a case is splenectomy or splenopexy especially in children and here, in this case splenectomy was done.
