Pulmonary valve cyst mimicking pulmonary artery neoplasia: a case report

Abstract

Cardiac valve cysts are rare beyond infancy. The tricuspid and mitral valve are the most common sites, with few reported cases of pulmonary valve cysts in the literature. This case illustrates a pulmonary valve cyst mimicking a tumour in a child 13 years after cardiac surgery. Although these lesions are extremely rare, they could be considered in the differential diagnosis in patients presenting with valvular mass lesions.

Giant blood cyst, isolated dysgenesia of pulmonary valve and pulmonary artery aneurysm: a rare combination

“…Cardiac valve cysts are a rare clinical condition in adults, mostly arising from the atrioventricular valves [1]. Blood cysts of the pulmonary valve are extremely rare, which are usually on the arterial surface of the posterior (either right or left) cusp [2].…”
