The MRI sequences reveal a lobulated soft tissue mass centered on the posterosuperior wall of the right maxillary sinus measuring 33x20x18 mm. It displays an intermediate signal on T1WI, high signal on T2WI and enhances intensely on post-contrast sequences. It shows a posterior extension to the pterygomaxillary fissure as well as a superior extension to the inferomedial extraconal space with partial destruction of the orbital floor.
Case Discussion
