Answer

Chest radiograph and soft tissue neck radiography/CT or ultrasonography may show prevertebral soft tissue swelling, enlarged epiglottis, and narrowing of the subglottic region.

Echocardiography may demonstrate valvular vegetations; however, this systemic manifestation of diphtheria is rare. [23, 24]
