A rare cause of dysphagia: compression of esophagus by a giant thoracic spine osteophyte.

A 76-year-old man presented to our department complaining of dysphagiawhich had started 6 months earlier as mild and had gradually progressed for the last month. He indicated that it was mainly limited to solids and was relieved by fluids. He had no pain while swallowing. The patient was a nonsmoker and his medical history included hypertension and osteoarthritis. An upper gastrointestinal endoscopy was performed and revealed a smooth, extrinsic indentation on the left posterior wall of the mid-esophagus (●" Fig.1). The esophagus appeared otherwise normal without any evidence of the formation of any intrinsic structure. Cervical–thoracic computed tomography (CT) was performed for differential diagnosis. This revealed fusion between the T2–T5 corpora and diffuse idiopathic skeletal hyperostosis (DISH), with prominent osteophyte formation projecting anteriorly on the left at the T2–T3 level. This formation pressed on the esophagus, as shown in the CT image (●" Fig.2). Severe dysphagia related to thoracic osteophytes was diagnosed. A surgical consultation was arranged and an operation for osteophyte excision was proposed. However, the patient refused surgical intervention, so diet modification and antireflux and swallowing therapy were prescribed and explained to him. Dysphagia is a common problem in older patients and is becoming a larger health care problem. Dysphagia can occasionally be caused by giant vertebral osteophytes or exuberant bone formation associated with DISH. Almost all reported cases have resulted from large anterior osteophytes in the cervical spine, which commonly involve the hypopharynx or the cervical esophagus. It has been suggested that osteophytes are more likely to cause narrowing of the cervical esophagus, because in the cervical spine the cricoid cartilage fixes the esophagus, whereas the thoracic esophagus is a relatively mobile structure that can be displaced anteriorly or laterally without being compressed [1], and for this reason dysphagia related to thoracic esophagus involvement is very rare [2].
