Splenosis Mimicking Lymphoma Relapse Confirmed by F-FDG PET/CT and Tc-99m Nano-colloid Scintigraphy Thirty Years After Splenectomy for Trauma.

Splenosis is implantation of the splenic tissue in the abdominal region or elsewhere in the body as a consequence of trauma or splenectomy, which might mimic intra-abdominal involvement of several malignancies. This case report presents a patient with abdominal implants without F-FDG accumulation confirmed to be splenosis by Tc-99m nano-coloid scintigraphy.
