Synchronous bilateral tonsillar carcinoma: role of fluoro-deoxyglucose positron emission tomography scanning in detecting occult primary tumours in metastatic nodal disease of the head and neck.

We present the second case of primary synchronous bilateral tonsillar squamous cell carcinoma reported in the English literature and evaluate the role of fluoro-deoxyglucose positron emission tomography scanning in the search for the occult primary tumour in a patient presenting with metastatic nodal disease in the head and neck.
