Laryngeal Giant Cell Tumor Mimicking Thyroid Cancer Demonstrated by PET/CT

摘要

A 53-year-old man was referred for combined F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET)/computedtomography (CT) imaging to evaluate a protruding mass in the right anterior neck. PET/CT images showed a level III nodular lesion with intense FDG uptake in the above-mentioned region. Surgical excision was performed under the impression of thyroid cancer. Histopathologic evaluation, however, revealed a giant cell tumor of thyroid cartilage.
