Gastric Outlet Obstruction: Don't Miss Duodenal Tuberculosis.

We report a case of isolated duodenal tuberculosis (TB) in a patient who presented with features of gastric outlet obstruction. The diagnosis was made on repeat endoscopic duodenal biopsy after initial histopathology failed to reveal the diagnosis. The patient recovered with antitubercular therapy. The index of suspicion has to be high in TB endemic countries as clinical, radiological, and endoscopic features are nonspecific.
