Abstrakt: A 15-year-old boy presented with a sudden onset of breathlessness for 7 days, gradual loss of weight of 17.6 lbs over the last month and progressive hoarseness of voice for 7 months. The contrast-enhanced computed tomography (CECT) scan revealed a heterogeneously enhancing lesion in the anterior mediastinum with multiple discrete lymph nodes in the cervical and mediastinal locations. The GeneXpert MTB/RIF assay performed on the CT-guided biopsy of the mass was negative, but the culture for Mycobacterium tuberculosis was positive at 7 weeks of incubation. There was a suboptimal radiological response after 6 months of treatment. First-line drug susceptibility testing (DST) performed by line probe assay (LPA) on the positive culture detected high-level resistance to isoniazid. The treatment was modified as per DST results to which the patient responded well. [ABSTRACT FROM AUTHOR]
