Extrinsic esophageal compression by the vertebral body

A 78-year-old woman with hypertension, diabetes, dyslipidemia, and revascularized ischemic heart disease was diagnosed with gastric adenocarcinoma in 2011, with suspected bilateral adrenal metastatic disease, and was treated with subtotal gastrectomy and palliative chemotherapy. A follow-up gastroscopy in 2015 identified a protruding, erosive mid-esophageal lesion suggestive of extrinsic compression or ulcerated submucosal lesion, which had not been described previously. Follow-up was advised, and the lesion persisted after three months. The patient had no esophageal symptoms, and subsequent thoracoabdominal CT scans found no bony abnormalities in the cervicothoracic spine or mediastinal changes. Endoscopic ultrasound was recommended given the patient's cancer history.
