Abstract:
Prostate cancer metastases to the thyroid cartilage is an extremely rare phenomenon. We report three cases of advanced prostate carcinoma with metastases to the thyroid cartilage identified on 18F prostate-specific membrane antigen-1007 (PSMA-1007) positron emission tomography (PET)/computed tomography (CT). The pathophysiology and possibility for under-reporting are also discussed. Prostate cancer metastases to the larynx should be considered in the differential diagnosis of thyroid cartilage lesions in patients with advanced prostate cancer and is associated with poor prognosis.
