A man in his 30s with a medical history of asthma, social history of smoking, and allergy to shellfish presented to the emergency department with tongue swelling. The patient reported a history of a local burn from hot food but denied any history of trauma, foreign body, or piercing. He was evaluated, given a presumptive diagnosis of sialadenitis, and discharged home with ibuprofen and clindamycin. He returned several days later with worsening tongue swelling, voice change, and subjective fever. Postcontrast axial computed tomography (CT) demonstrated a midline lesion within the oral tongue that was predominantly hypodense and demonstrated rim enhancement. No calcifications were seen within the lesion (Figure, A). The lesion was predominantly isointense to muscle on axial T1-weighted images without intravenous (IV) contrast (Figure, B). Axial T2-weighted images with fat saturation showed predominantly hyperintense signal relative to muscle as well as punctate internal foci of T2 hypointensity (not shown). The lesion was hyperintense on diffusion-weighted imaging (Figure, C) and hypointense on the apparent diffusion coefficient map (not shown). Sagittal T1-weighted magnetic resonance imaging (MRI) with IV contrast and fat suppression demonstrated signal hypointense to muscle centrally with peripheral enhancement (Figure, D).

Approximately 50 cases of glossal abscess have been reported in the English literature during the past 40 years.1 The diagnosis of glossal abscess can be reached clinically. The patient may have tongue swelling, fever, and pain radiating toward the ears. However, in one study, more than 50% of the patients had no clinical or laboratory findings to suggest glossal abscess.2
The typical imaging features of glossal abscess are similar to those of abscesses found in other parts of the body: restricted diffusion, central fluid signal (T1 hypointensity, T2 hyperintensity), peripherally enhancing wall, and perilesional edema.3 However, when small, they can present with uniform hypointensity on T1-weighted images that enhance diffusely after the administration of intravenous contrast. Most tongue abscesses are located within the oral tongue.2
