A 35-year-old man presented to a community otolaryngologist with a 6-month history of dysphagia. Evaluation revealed a left-sided tongue base mass that involved the lateral pharyngeal wall, base of the tongue, and vallecula. The lesion was debulked, and the patient was referred to our facility. Magnetic resonance imaging showed signal irregularity at the base of the tongue on the left side, without infiltration of the tongue musculature. Positron emission tomography–computed tomography demonstrated an area of uptake at the base of the tongue on the left side corresponding to the signal irregularity on magnetic resonance imaging.
