Metastatic prostate carcinoma presenting as a superscan on Ga-68-PSMA PET/CT

摘要

We describe the finding of a metastatic superscan detected by Ga-PSMA PET/CT imaging. A 63-year-old man with metastatic prostate carcinoma underwent Ga-PSMA PET/CT imaging for staging and evaluation of the most appropriate therapeutic option. Images demonstrated diffuse and extensive skeletal uptake in the axial and appendicular skeleton, corresponding to the typical red marrow distribution. Intense soft tissue uptake was also seen in the prostate and multiple pelvic and abdominal lymph nodes.
