  • Title: Pseudotumor of the nasal fossa secondary to mucoid impaction in choanal atresia.
    Author: Kleinman P, Winchester P.
    Journal: Pediatr Radiol; 1975 Nov 24; 4(1):47-8. PubMed ID: 1233455.
    Abstract:
    An intranasal mass was discovered during evaluation of unilateral choanal atresia. Radiologic investigation of the lobulated cystic mass showed no communication with the central nervous system or any other bony abnormalities. During surgery for the choanal atresia, the mass proved to be a mucous impaction. The case illustrates the need to utilize decongestants and aspiration prior to instillation of contrast agent.
