Abstract

Actinomycosis is a bacterial infection caused by Actinomyces species that are commensal in the human oral cavity, digestive tract, and genital tract. The present case highlights actinomycosis of the hypopharynx, mimicking malignancy in 18F-fluorodeoxyglucose positron emission tomography-computed tomography.

Keywords

Actinomycosis of hypopharynx - carcinoma of unknown primary - false positive - head and neck malignancy - positron emission tomography-contrast enhanced computed tomography
