Figure 28b.

Tonsillitis in a 15-year-old boy who presented to the emergency department with fever, sore throat, malaise, and right neck swelling and was diagnosed with elevated d-dimer levels and inflammatory marker levels. The test results were positive for COVID-19. (a–c) Axial (a) and coronal (b, c) contrast-enhanced neck CT images show enlarged palatine tonsils (black arrows in a and arrows in b). A subtle ill-defined asymmetric area of hypoattenuation is depicted within the enlarged left palatine tonsil, consistent with phlegmon or early abscess (white arrow in a). Associated cervical lymphadenopathy (arrows in c) is depicted. (d) Sagittal power Doppler US image of the right superior neck shows a near-complete occlusive thrombus (arrows) in the right jugular vein (RT IJV).
