Abstract

We describe a congenital tracheal web malformation in a wild female brown bear (Ursus arctos) yearling that was euthanized after being hit by a train in Norrbotten County, Sweden, December 2010. A 3-cm-long, abnormal, longitudinal mucosal fold divided the trachea into two halves, without obviously blocking the airflow.
