Resumen La esplenosis se define como el autotrasplante heterotopico de tejido esplenico como resultado de una rotura del bazo por trauma o cirugia. Es una condicion benigna y de hallazgo casual, aunque en ciertas ocasiones las pruebas de imagen puedan orientar a malignidad simulando tumores renales, linfomas abdominales y endometriosis, entre otros. Presentamos el caso de un varon de 42 anos al que, tras un estudio por dolor abdominal, se le realiza una resonancia magnetica en la que se observan multiples adenopatias en el abdomen que pueden orientar a un sindrome linfoproliferativo. Como antecedente importante, presenta esplenectomia por trauma abdominal a los 9 anos. Tras varios estudios, se decide realizar una gammagrafia con hematies desnaturalizados marcados con tecnecio-99m que muestra multiples depositos patologicos distribuidos por todo el abdomen e, incluso, la pelvis, siendo este hallazgo compatible con esplenosis.

Splenosis is defined as the heterotopic autotransplantation of splenic tissue because of a ruptured spleen due to trauma or surgery. It is a benign and incidental finding, although imaging tests may sometimes orient toward malignancy simulating renal tumors, abdominal lymphomas, endometriosis, among other. We report the case of a 42-year old male in whom a MRI was performed after a study due to abdominal pain. Multiple enlarged lymph nodes were observed in the abdomen, suggestive of lymphoproliferative disease. As an important background, splenectomy was carried out due to abdominal trauma at age 9. After several studies, it was decided to perform a (99m)Tc-labeled heat-damaged red blood cell scintigraphy that showed multiple pathological deposits distributed throughout the abdomen, and even the pelvis, being consistent with splenosis.
