title: Asymptomatic metastasis to cricoid from prostate carcinoma: an incidental finding detected on 18F-choline PET/CT.
abstract: Metastases to the larynx from prostate carcinoma are rare. We describe a case of asymptomatic prostate carcinoma metastasis to the right cricoid cartilage detected on 18F-fluorocholine PET/CT. This was histologically proven on open biopsy and the patient was offered local radiotherapy.
