Radiological assessment of a rare potentially lethal acute neck infection in emergency: Ludwig’s angina (A case report)

Ludwig angina is a potentially lethal acute cellulitis of the floor of the mouth and neck, including submandibular, submental and sublingual spaces and ultimately leading to airway obstruction. Computed tomography (CT) of the neck with upper thorax has been used in emergency once the airway obstruction is secured to evaluate the severity of the infection, to assess any abscess and mediastinal extension. Therefore knowledge of imaging features of Ludwig’s angina is essential to ensure an accurate diagnosis and initiation of early treatment. CT also plays an important role in evaluation for need of surgical intervention. However, MRI is superior to CT because of its excellent soft tissue contrast and demonstration of various fascial compartments' involvement.
