case_images: (a) Non-contrast CT of the sinuses revealed a mass with heterogeneous density in the left maxillary sinus, smooth bony destruction of the left medial and lateral maxillary sinus walls, extension into the nasal cavity, and erosion of the left inferior orbital wall. Arrows demonstrate regions of bony destruction with the lesion crossing the midline septum and eroding through the floor of the maxillary sinus and involving the alveolus and (b) magnetic resonance imaging with gadolinium revealed a heterogeneously enhancing mass with foci of high T1 and low T2 signals suggesting blood products.

case_images: CT of the sinuses revealed a large sinonasal mass with heterogeneous density in the left maxillary sinus, smooth bony destruction of the left medial and lateral maxillary sinus walls, extension into the nasal cavity, and erosion of the left inferior orbital wall (Figure 1(a)). MR imaging with gadolinium revealed a heterogeneously enhancing mass with foci of high T1 and low T2 signals suggesting blood products (Figure 1(b)).
