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.
脾组织自体移植是指因外伤或手术导致脾脏破裂后，脾组织发生异位自体移植。它是一种良性的偶然发现，尽管影像学检查有时可能会倾向于诊断为类似肾肿瘤、腹部淋巴瘤、子宫内膜异位症等的恶性病变。我们报告一例42岁男性病例，该患者因腹痛进行检查后接受了磁共振成像（MRI）检查。腹部发现多个肿大淋巴结，提示存在淋巴增殖性疾病。重要的既往史是，患者9岁时因腹部外伤接受了脾切除术。经过多项检查后，决定进行（99m）锝标记热损伤红细胞闪烁扫描，结果显示腹部甚至盆腔均有多处病理性沉积物，符合脾组织自体移植表现。
