case_images: Magnetic resonance imaging (MRI) study of head and neck. A, Axial MRI scan showing a significantly increased signal of the bone marrow lesion (yellow arrow) when compared with left mandibular body (asterisk), with bone edema indicative of an inflammatory process taking place in the right mandibular body and gas tracking along the two pterygoid muscles (white arrows). B, A coronal T2-weighted image of the submandibular region showing a wide mass with very high signal intensity from the parapharyngeal space to the inferior cervical region with associated edema.

case_images: Fig1
case_images: Magnetic resonance imaging (MRI) study of head and neck showed an increased signal of the right mandibular body, consistent with the diagnosis of right jaw osteonecrosis (Figure 1A), and a second high-intensity area characterized by gas formation spread for about 10 cm with involvement of the right parapharyngeal space and with extension to skin and muscle, suggestive of a gas-forming necrotising fasciitis of the neck (Figure 1B).
