Patient, male, 66 years old. Due to the right side of the nasal obstruction for 5 years, bilateral nasal obstruction for 3 years, admitted on August 12, 1991. Physical examination: the general situation is good. The right posterior segment of the nasal cavity has seen irregular white matter, and nasal wall adhesions. Nasopharyngeal microscopy: See after the nostril about 2cm × 2.5cm × 2.5cm of the gray-white lobular mass, palpation texture hard, and the right side of the nasopharynx and the top wall connected. X-ray sinus Valsalva, nasopharyngeal lateral radiographs and skull base radiographs showed a lobular soft tissue mass on the upper wall of the nasopharynx. The densities were uniform and the edges were clear with a size of 3 cm × 2.5 cm × 2.5 cm.
