RT Journal Article SR Electronic T1 Bilateral nasolacrimal duct mucocele, a rare cause of respiratory distress: CT findings in two newborns. JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 1011 OP 1013 VO 14 IS 4 A1 M Castillo A1 D F Merten A1 M C Weissler YR 1993 UL http://www.ajnr.org/content/14/4/1011.abstract AB Two newborns presented with severe respiratory distress caused by nasal obstruction. CT showed bilateral soft-tissue masses located under the inferior turbinates at the level of the inferior meatuses. Histologic examination showed the lesions to be compatible with nasolacrimal mucoceles. The embryology and radiographic features of this rare anomaly are discussed.
