Incidental finding of tall cell variant papillary thyroid carcinoma on prostate-specific membrane antigen PET CT scan.

Prostate-specific membrane antigen (PSMA) PET CT is widely used for staging and restaging of prostate cancer. Thyroid and other non-prostatic pathology may be incidentally identified by this imaging modality. Such findings warrant further investigation given their malignant potential. We describe the first reported case of PSMA avid T cell-variant papillary thyroid carcinoma incidentally detected on PSMA PET CT.
