title: Recurrent laryngeal nerve palsy secondary to massive venous thrombosis.
abstract: Retrospective review of all patients with recurrent laryngeal nerve palsy seen at a comprehensive cancer centre over a 30 month period has revealed three patients with this diagnosis apparently related to massive venous thrombosis. All three patients had an underlying diagnosis of malignancy (two colon, one breast) and an indwelling central venous access device with its tip in the superior vena cava. Direct laryngoscopy was otherwise normal in all patients, and two had normal CT scans of the neck and mediastinum. This third patient had mediastinal adenopathy, but this was unchanged from the previous nine months. Although two patients expired shortly after this presentation, the other patient lived for one year and his palsy resolved with the resolution of his superior vena cava syndrome. Mediastinal inflammation secondary to the thrombophlebitis may be the direct cause of this unusual presentation.
