Esophageal Tuberculosis in a Patient on Maintenance Dialysis: Advantages of Interferon-Gamma Release Assay

Patients with chronic renal failure have a higher risk of developing tuberculosis compared to the general population, and especially extra-pulmonary tuberculosis. This pathology is often difficult to diagnose and requires a combination of multidisciplinary examinations. The confirmation of the diagnosis is important in order to quickly match the treatment with the pathology. We report a patient with primary esophageal tuberculosis for whom the interferon gamma release assay facilitated a timely diagnosis.
