Abstract
Images of a case of unilateral choanal atresia diagnosed in a 35-year-old woman are presented. This is an uncommon diagnosis in an adult patient, and a less frequently encountered form of the condition. In more than 90% of cases of choanal atresia, the abnormality is partly or completely osseous; pure membranous atresia is rare. It is unilateral in 50 - 60% of cases, and more than 75% are associated with syndromes and systemic anomalies.

Unilateral choanal atresia may go unrecognised until adulthood, as in our patient, when she presented with rhinorrhea and unilateral recurrent nasal obstruction
Careful suctioning prior to the scan may be helpful in some patients
Summary
