RESUMO
We describe the case of a 55-year-old man who presented with history of fever for 3 months that began 2 months after he had undergone open reduction and internal fixation of left humerus fracture. Implant infection was suspected, but conventional imaging remained unyielding. Ga-DOTA ubiquicidin PET/CT showed increased tracer uptake along the entire length of the implant in the left humerus. Implant removal and temporary external fixation were done. In 24 hours, the patient became afebrile, and blood culture on the fourth day was sterile.

65-year-old man with left-sided pelvic pain on evaluation was found to have features suggestive of either Paget disease or prostatic bone metastasis of the left hemipelvis based on Tc-MDP bone scan and MRI. Ga-PSMA PET/CT to assess the possibility of primary prostate cancer and if present to stage it helped to rule out prostate cancer because of absence of focal abnormal increased tracer uptake in the prostate gland. However, false-positive tracer uptake was noted in the left hemipelvis, which was subject to biopsy and histopathologically proven to be Paget disease involvement.
