The next day, pacing failed and chest radiography showed that the right ventricular lead was outside the cardiac silhouette. Computed tomography revealed that the lead had perforated the right ventricular apex, causing a left-sided pneumothorax and a cystic lesion at the site of pulmonary injury by the pacemaker lead. The patient underwent lung resection and a right ventricular lead extraction. Pathological analysis revealed the cystic lesion to be an acute pneumatocele.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Pneumothorax and pneumatocele associated with right ventricular pacemaker lead perforation is extremely rare.
