An Unusual Presentation of Tuberculosis With Dysphagia

About a quarter of the world’s population is infected with tuberculosis (TB). It is one of the leading causes of death worldwide. However, the prevalence of TB in the United States is rare. Pulmonary TB is the commonest form of TB. Most patients with TB present with pulmonary symptoms. Extrapulmonary TB usually presents with symptoms related to the organ system involved and can present with very unusual symptoms. TB presenting with dysphagia is uncommon, and spinal TB presenting with dysphagia is very unusual. A 57-year-old woman presented to the emergency department with a four-month history of dysphagia and chest pain. She was undergoing an outpatient workup of her symptoms that included esophagogastroduodenoscopy, gastric emptying study, and computed tomography (CT) scan of the chest, which showed incidental findings of a focus in the thoracic spine. It was followed by a bone scan, and the results were concerning for malignancy. She was awaiting an oncology appointment when she presented to us. A basic workup after her presentation that includes complete blood count, comprehensive metabolic panel, troponin, chest x-ray, and electrocardiogram was unrevealing. Magnetic resonance imaging (MRI) of the thoracic spine showed findings suggestive of tuberculous spondylitis, tuberculous paraspinal, and prevertebral abscesses. Chest CT was repeated, which showed mass effect and erosion on the posterior esophageal wall with anterior displacement of the esophagus. Tissue biopsy revealed acid-fast bacilli (AFB) on AFB stain, and the culture grew Mycobacterium tuberculosis. She was successfully treated with the antitubercular regimen of rifampin, isoniazid, ethambutol, and pyrazinamide. TB can present with a myriad of symptoms, and although rare, it can present with symptoms like dysphagia. In patients with a history of travel to or immigration from an endemic region, previous infection, and immunosuppression, TB should be considered as one of the differential diagnoses even for unusual symptoms like dysphagia.
