A 41-year-old woman attended hospital with a 2-week history of a post-prandial, left upper abdominal pain. The patient underwent upper gastrointestinal endoscopy, and multiple round oesophageal submucosal lesions (figure 1A) were observed. On ultrasound, these abnormalities were echoless and were identified as outside the oesophageal wall with blood flow detected by colour Doppler flow imaging. Moreover, one of the lesions was connected to the aorta (figure 1B). There were no other abnormalities reported by the patient in terms of medical history and, in particular, there was no history of genetic disease. The rest of the physical examination and laboratory tests did not reveal any clinical anomalies, although the patient reported a 10-day history of cough and dysphagia 2 months previously, at which time a chest CT scan showed no obvious cause.
