Pulmonary varices presenting as a solitary lung mass in a patient with end-stage liver disease.
A man undergoing evaluation for liver transplantation was found to have an asymptomatic chest mass, which further evaluation revealed to be pulmonary varices. The left hilar lesion was discovered on a screening chest x-ray film and confirmed by a computed tomographic scan of the thoracic cavity. Bronchoscopy was nondiagnostic, and a thoracotomy was required to diagnose the vascular lesion and exclude carcinoma. The pathophysiology of this pulmonary venous anomaly appeared to be related to portal hypertension, since esophagogastric and colonic varices also were present and the pulmonary varices resolved after liver transplantation. This is the first reported case of pulmonary varices caused by portal hypertension.
