A 55-year-old man presented to the emergency department (ED) with a 2-day history of severe, sharp pain on the right side of the throat. He also reported being unable to swallow because of the pain. He denied fever, chills, dyspnea, recent dental work, or oral trauma. Vital signs were unremarkable and he was not immunosuppressed. Physical examination revealed significant swelling and tenderness on the right side of the tongue and sublingual space ( Figures 1 and 2 ). A computed tomography (CT) scan was performed ( Figures 3 and 4 ).
