A 56-year-old man was transported to our emergency department complaining of massive haematemesis. The initial vital signs included a blood pressure of 190/100 mm Hg and a pulse of 141 beats per minute. His past medical history was significant for pulmonary tuberculosis, which had been diagnosed and treated for 10 months, 7 years earlier. His haemoglobin and haematocrit on initial presentation were 7.5 g/dl and 22.8%, respectively. We obtained a computed tomography scan of the chest (fig 1).
