Description	Radiopaedia case ID: 51367 Image ID: 28722371 Image stack position: 16/51 Plane projection: Axial Aux modality: T1 C+ fat sat Study findings: There is extensive T2 hyperintense edema and enhancement involving the soft tissues of the left deep face including the infratemporal fossa and pterygopalatine fossa. The left maxilla alveolus is expanded, with abnormal T1 dark marrow signal and lack of normal enhancement. The adjacent hard palate mucosa is swollen and edematous. There was also lack of normal enhancement of the left inferior turbinate. Modality: MRI System: Head & Neck Findings: Non-contrast CT head showed no acute intracranial abnormality. However, there is near complete opacification of the left maxillary sinus with soft tissue extension into the premaxillary and retromaxillary space. There is also subtle abnormal fat stranding in the left superior parapharyngeal and masticator space around the pterygoid muscles. Invasive infectious process was suspected and an urgent MRI sinus with contrast and ENT consult were recommended.
