We present a case of biopsy-proven prostatic adenocarcinoma with a tracer-avid left paravertebral location at D4 to D5 vertebrae, suggestive of metastasis. However, in view of uncommon location of single-site metastasis at paravertebral region with no tracer-avid regional lymphadenopathy, image-guided biopsy was done, which was suggestive of paraganglioma. 68Ga-PSMA is known to have variable tracer avidity in multiple nonprostatic benign as well as malignant lesions, and our case adds to the list of nonspecific uptake by this once considered “specific” to prostate PET radiotracer.
