Drug-resistant pulmonary tuberculosis presenting as mass lesion

A 33-year-old woman presented with a 1-month history of dry cough, fever, reduced appetite and weight loss. She had taken antitubercular therapy about a year prior with partial improvement in symptoms. At initial presentation, a plain chest X-ray followed by a contrast-enhanced chest CT scan was advised. The CT scan image was suggestive of a right upper lobe mass lesion. Since the patient had no sputum production, a diagnostic flexible bronchoscopy was performed. The bronchoalveolar lavage fluid analysis along with ultrasonography-guided lung biopsy was diagnostic of multidrug-resistant tuberculosis.
