Abstract
- Esophageal tuberculosis is rare, and may result from the direct extension of tuberculosis infection from adjacent mediastinal lymph nodes. Endosonography can be used to evaluate heterogeneous or homogeneous hypoechoic masses in the esophageal wall, interruption of the esophageal adventitia, and mediastinal lymphadenitis. We admitted a 19-year-old woman to our hospital because of weight loss and chest pain. Endoscopic observation revealed an esophageal submucosal mass and central ulceration with exudates. Endosonography showed a homogeneous hypoechoic mass with a destroyed esophageal wall layer, spot-like hyperechoic foci, and multiple enlarged lymph nodes in the mediastinum. A biopsy showed acute inflammation, while the results of the polymerase chain reaction (PCR) and interferon-gamma tests were positive for tuberculosis. The patient was diagnosed with esophageal tuberculosis using endosonography and she responded well to anti-tuberculosis therapy. Endosonography may be useful in the diagnosis of esophageal tuberculosis when an accurate histologic diagnosis is not established.
