title: Retronasopharyngeal lipoma: a case report.
abstract: We present an unusual and challenging case of impending upper airway obstruction in a pediatric patient that resulted from a benign disease process. Although rare, a lipoma should be considered in the differential diagnosis of nasopharyngeal obstruction. When a nasopharyngeal lipoma is discovered, radiologic and histopathologic studies should be performed to rule out an aggressive lipoma, such as an infiltrating (intramuscular) lipoma or angiolipoma. The use of CT scanning or magnetic resonance imaging is invaluable in diagnosis, evaluation of extent of disease, adn management of this condition. Close followup is imperative.
