Schatzki's ring. An unusual clinical and radiological presentation

Schatzki's ring is a lower esophageal mucosal ring associated with a small sliding hiatus hernia. Most investigators described it as either an asymptomatic or symptomatic entity with chronic recurrent presentation of dysphagia. Barium swallow study in patients with Schatzki's ring was described as a thin smooth circumferential constriction at the GE junction. This case report describes an unusual clinical and radiological presentation in a patient with Schatzki's ring. Our adult male patient experienced sudden dysphagia, followed by spontaneous relief after an interval of 12 hours without specific treatment. Radiological findings were highly suggestive of lower esophageal malignancy. However, this possibility could be excluded by upper endoscopy and histopathological examination of biopsies taken from the lesion. The condition was diagnosed as Schatzki's ring with unusual clinical and radiological presentation.
