Maxillary Sinus Sarcoma

Fig. 13.10a The left maxillary sinus and the nasal cavity are obliterated; the osseous nasal septum, the left sided conchae, and the medial orbital wall (also called lamina papyracea) are destroyed on this coronal CT image viewed in bone window settings. b On this coronal MR image after contrast administration, a homogeneously enhancing mass in the nasal cavity and its extension into the frontal sinus are shown. The maxillary sinus was, in retrospect, opacified secondarily to retention of fluid. Are you looking at a T1- or a T2-weighted sequence?
