    Clinical introduction

    A 76-year-old man presented to the ED following a fall. He was unconscious initially and complained of dizziness on arrival. There was no recent history of trauma, chest or back pain, headache, fever prior to the episode. His vital signs were: BP, 98/42 mm Hg; RR, 20 breaths/min; and an oxygen saturation level of 97% while breathing ambient air. Physical examination revealed mild laboured breathing, bilateral lung rales and diastolic heart murmur at left sternal border. No oedema was apparent in the extremities. Brain CT, electrocardiography and laboratory studies were unremarkable. Chest radiography was obtained (figure 1).
