Superscan-Like Pattern on 18F-Choline PET/CT in a Patient With Essential Thrombocythemia.

Few clinical and preclinical articles reported the potential usefulness of 18F-choline PET/CT in several hematological proliferative diseases. We report and incidental finding of a superscan-like pattern in a patient affected by essential thrombocythemia (ET), performing 18F-choline PET/CT for a biochemical recurrence of prostate cancer. The mild elevation of PSA values and the negativity of subsequent 68Ga-PSMA-11 PET/CT allowed to correlate the diffuse skeletal uptake detected on 18F-choline PET/CT to the underlying hematologic disease, rather than to a prostate cancer relapse.
