Oesophageal submucosal haematoma in a patient with acute coronary syndrome

A man in his mid-70s presented with recent-onset angina. An ECG revealed ST-segment depression, and he was started on treatment under the diagnosis of acute coronary syndrome. 12 hours after admission, he developed haematemesis and dysphagia. A circular mass posterior to the left atrium was found on echocardiography, subsequently, CT revealed oesophageal submucosal haematoma. Anticoagulation therapy was withdrawn, and he showed gradual improvement. Follow-up CT on the 10th day revealed a complete resolution. 3 weeks later, he underwent a successful coronary artery bypass graft procedure and is currently well at 3 months of follow-up.
