title: Herniated Thoracic Spleen Mimicking Lung Metastasis on 68Ga-Labeled Prostate-Specific Membrane Antigen PET/CT in a Patient With Prostate Cancer.
abstract: We report a case of clinically asymptomatic patient of prostate cancer who was previously subjected to radical prostatectomy presenting with a rising serum prostate-specific antigen level of 6.6 ng/mL. Whole-body PET/CT with Ga-labeled prostate-specific membrane antigen ligand was performed to assess for disease recurrence, which revealed an intense tracer uptake in a soft tissue mass in left hemithorax mimicking lung metastasis; which later turned out to be splenic tissue.
