title: Neoplastic obstruction of the trachea complicating pseudobulbar palsy.
abstract: We have reported a case of pseudobulbar palsy with airflow obstruction initially attributed to chronic aspiration and chronic airflow obstruction caused by cigarette smoking. The finding of stridor led to a detailed evaluation of the obstruction. Flow-volume loops, fiberoptic bronchoscopy, CT scan of the upper thorax, and fine-needle biopsy of a lesion of the trachea were required to make the diagnosis of non-small-cell carcinoma involving the trachea.
