68Ga-PSMA Uptake in Escherichia coli Spondylodiscitis.

In a patient with recently diagnosed intermediate-risk prostate cancer, Ga-prostate-specific-membrane-antigen (PSMA) PET/CT for primary staging discovered increased Ga-PSMA uptake in spondylodiscitis in the thoracic spine. The bacteria Escherichia coli was found both in blood cultures and bone biopsies from the thoracic lesion. This case presents spondylodiscitis as a potential benign pitfall to be aware of when interpreting PSMA PET/CT in prostate cancer patients.
