A rectangular hypoattenuating structure of 10 mm length and 6 mm height and width, respectively, is seen within the mid third of the right nasal cavity. The structure is located in the position of the former middle nasal meatus and is negative for contrast enhancement. Marked regional turbinate destruction is noted, as well as focal destruction of the nasal septum, adjacent to the rectangular object with mild extension of the destructive changes into the left nasal cavity. Slight regional mucosal swelling is noted, as well as a mild amount of fluid attenuating material on the floor of the right nasal cavity. The submandibular and medial retropharyngeal lymph nodes present within normal limits.
