  		Fig 1. A, Axial T2 MR imaging at the level of the hard palate shows an enlarged right lateral retropharyngeal lymph node (asterisk). B, Coronal T1 postgadolinium scan with fat saturation through the nasal cavity and orbits shows the large esthesioneuroblastoma with extensive orbital and intracranial invasion. The arrow shows a peritumoral cyst.

  		Fig 3. A, Axial contrast-enhanced CT through the level of the mandible demonstrates bilateral enhancing masses within the submandibular glands. B, Axial contrast-enhanced image of the skull base at the level of the hard palate shows an enhancing right lateral retropharyngeal lymph node (asterisk) and 2 enhancing left superficial parotid masses.

  		Fig 4. A, Axial noncontrast CT image at the level just caudal to the hard palate demonstrates an enlarged right lateral retropharyngeal lymph node (asterisk) causing mass effect on the adjacent parapharyngeal fat. B, Axial noncontrast CT image of the skull base at the level of the torus tubarius showing the postsurgical changes within the nasal cavity and nasopharynx from craniofacial resection.
