18F-NaF PET/CT in Prostatic Calculi.

Primary prostatic calculi commonly present asymptomatically in men over the age of 50 years. Individual calculi form when the secretory tube is blocked by inflammation, prostatic secretions, or corpora amylacea. Although small prostatic calculi have been described as a component of normal aging, increased prevalence of calculi has been associated with benign prostatic hyperplasia and prostatitis. We are presenting prostatic calcification in a 69-year-old man as incidentally detected on F-NaF PET/CT. Although previous publications have reported F-NaF uptake portraying calcification in soft tissue, these findings demonstrate a new domain in which to assess calcium metabolism using F-NaF PET/CT.
