Abstract

An unusual presentation of thoracic aortic dissection in a 73 year old man is described. He was admitted to hospital with severe left sided pleuritic chest pain. Examination on admission was normal apart from minor tenderness on palpation of the left lower chest wall. Chest x ray showed cardiomegaly with right lung shadowing, and ventilation/perfusion scan was negative. Spiral computed tomography done on the fourth day showed a false lumen on the ascending aorta. He underwent surgery but deteriorated postoperatively because of intrathoracic bleeding and developed cardiac tamponade from which resuscitation was not possible.
