Chagasic megaesophagus in coinfection with tuberculosis: diagnostic experience




Chagas disease, deglutition disorders, tuberculosis, megaesophagus, manometry


Chagas disease is associated with late complications, including chagasic megaesophagus that manifests with dysphagia, odynophagia and/or regurgitation; diagnosis by radiography, endoscopy, barium esophagram and manometry. A 70-year-old male patient presents with dysphagia from solids to liquids, regurgitation, decreased appetite and weight loss, fever, dyspnea on small exertion, productive cough. Chest X-ray impresses suspicion of megaesophagus, contrasted CT scan of the chest shows right parapneumonic pleural effusion, consolidated pneumonic significant high-risk origin of bronchial aspiration and dilatation of the esophageal body; Barium esophagogram shows a decrease in the caliber of the distal esophagus from the gastroesophageal junction, serology (ELISA) positivity for IgG antibodies to T. cruzi; and GeneXpert positive Mycobacterium Tuberculosis. The diagnosis of chagasic megaesophagus was incidental, although limited, there is evidence of Chagas disease in coinfection with pulmonary tuberculosis; It should be suspected in patients with chronic respiratory symptoms and dysphagia.
