Splenunculus Masquerading as Prostate-specific Membrane Antigen-positive Lymph Node Metastasis in a Patient With Prostate-specific Antigen Relapse After Radical Prostatectomy

摘要

A 45-year-old patient presented with prostate-specific antigen relapse after radical prostatectomy. Diagnostic workup revealed a Ga-68-labeled prostate-specific membrane antigen-targeted ligand tracer uptaking nodule that was initially interpreted as lymph node metastasis but eventually identified as a splenunculus by scintigraphy with Tc-99m pertechnetatelabeled heat-altered erythrocytes. Awareness of this constellation may spare unnecessary diagnostic procedures and inappropriate treatment. (C) 2016 Elsevier Inc.
