Abstract

Splenosis is a common finding after traumatic rupture of the spleen or therapeutic splenectomy, defined as a heterotopic autotransplantation of the spleen in peritoneal cavity and surface. In splenectomized patients due to hematologic disease, splenosis can lead to disease recurrence. We present a case of splenosis in a patient with idiopathic thrombocytopenic purpura who relapsed after splenectomy. For its localization, conventional imaging and scintigraphy with 99mTc-denatured red cells were performed, and at least five splenic foci were observed. Given the difficult intraoperative localization of these nodules, radioguided surgery was performed, with excellent localization and removal of all known nodules and multiple peritoneal implants of millimeter size that were not previously observed. We conclude that radioguided surgery is an excellent tool for locating foci of peritoneal splenosis, which have difficult access, thus avoiding early recurrence of the disease.

Resumen

La esplenosis es un hallazgo frecuente tras las la rotura traumática del bazo o esplenectomía terapéutica, definiéndose como un autotrasplante heterotópico del bazo por la superficie y cavidad peritoneal. En pacientes esplenectomizados por enfermedad hematológica, la esplenosis puede llevar a recidiva de la enfermedad. Presentamos un caso de esplenosis en un paciente con púrpura trombocitopénica idiopática (PTI) que presentó una recidiva tras esplenectomía. Para su localización se realizaron pruebas de imagen convencional y gammagrafía con hematíes desnaturalizados marcados con 99mTc, donde se apreciaron al menos 5 focos esplénicos. Dada la difícil localización intraoperatoria de dichos nódulos, se practicó cirugía radioguiada, con excelente localización y extirpación de los nódulos conocidos y de múltiples implantes peritoneales de tamaño milimétrico no visualizados previamente. Concluimos que la cirugía radioguiada es una excelente herramienta para la localización de focos de esplenosis peritoneal de difícil acceso y visualización, evitando así una recurrencia precoz de la enfermedad.
