Figure 13  Conventional ameloblastoma of the maxilla. A 61-year-old man with a several-month history of left-sided nasal congestion and facial pain. A-D: Coronal computed tomography (A and B), T2-weighted (C), and contrast-enhanced, fat-suppressed T1-weighted (D) magnetic resonance images reveal a large soft tissue mass occupying the left maxillary sinus and nasal cavity (arrows). The mass is T2 hyperintense and heterogeneously enhancing. There is focal dehiscence of the left lamina papyracea, with tumor extension into the orbit (arrowheads). Pathology confirmed ameloblastoma following resection.
