CTICasesIatrogenic Esophageal Ring
Imaging findings
CT shows a focal mid-esophageal web-like ring or stenosis in a patient with systemic sclerosis who has undergone multiple endoscopic dilations for esophageal dysphagia, representing scarring from chronic mucosal micro-tears.
Key takeaways
Repeated endoscopic balloon dilations for dysphagia in scleroderma patients can lead to chronic scar formation, resulting in a focal iatrogenic mid-esophageal ring or stricture rather than the typical diffuse patulous appearance.
