Treatment options included surgical resection, endobronchial dilation or stenting, and argon photocoagulation.

Ultrasonography in preclinical education: a pilot study.

Objective: To evaluate the ability of second-year medical students to use ultrasonography for identification of anatomic structures and pathologic conditions.
