Abstract

The small cell neuroendocrine variant is a rare subset of prostate cancer. We present the case of a patient who underwent a dual tracer 18F-Fluorocholine and 18F-DCFPyL PET/CT in the context of biochemical recurrence. Completely discordant results were found using both radiotracers, defining the biological heterogeneity in tumor expression and treatment response.
