ABSTRACT
ABSTRACT: A 76-year-old man undergoing hormone therapy for prostate cancer was referred for 68 Ga-PSMA-11-PET (PSMA PET) due to persistently detectable PSA level. No PSMA-positive tumor lesions were detected, so a delayed phase imaging was performed, which revealed focal PSMA uptake in the right seminal vesicle together with contrast accumulation on excretory phase contrast-enhanced CT. These findings were finally determined to be secondary to urinary reflux as a consequence of a prostatic enucleation he had undergone 5 months earlier following an episode of acute urinary retention.

ABSTRACT: A 75-year-old man presented with dyspnea for more than 2 months, with blood test showing low platelet count and cardiac ultrasound showing severe pulmonary hypertension (>54 mm Hg). A CT pulmonary angiogram showed a filling defect in the pulmonary trunk, right and left pulmonary arteries, raising the possibilities of pulmonary embolism or artery sarcoma. FDG PET/CT was performed for further evaluation and showed low uptake in the pulmonary wall, which supported the diagnosis of pulmonary embolism. Patient was treated with anticoagulants with no changes on repeated CT pulmonary angiogram. Patient underwent surgery, and histopatological examination revealed a pulmonary artery sarcoma.
