Abstract
A 54-year-old man with a history of tonsillar squamous cell carcinoma treated with chemoradiotherapy and an 18-year history of seropositive rheumatoid arthritis in remission without maintenance therapy presented with right cervical pain and dysphagia for several months. Flexible laryngoscopy did not show any lesion, and MRI revealed a necrotic lesion inside the thyro-hyo-epiglottic space attached to the hyoid bone. 18 F-FDG PET/CT demonstrated a moderately increased metabolic activity of the lesion without any other suspected lesions. Surgical resection was performed, and pathology revealed a necrotizing granuloma compatible with a rheumatoid nodule.
