From: Changes in chest CT findings of pulmonary tuberculosis after linezolid treatment
A, B, C Extensively drug-resistant tuberculosis in a 58-year-old man. He had been treated with antituberculosis drugs for 6 months before linezolid treatment. A and B. Transaxial thin-section CT scan shows a cavity (arrow) and bronchial wall thickening in the right upper lobe. Bronchial wall thickening and decreased volume in the right lobe are also noted. Calcified nodule ((B) mediastinal window, arrowhead) and pleural thickening with extrapleural fat proliferation are also observed. C. After 6 months of linezolid treatment, CT scan shows a persistent cavity with a decreased size and thin wall in the right upper lobe (arrow). Bronchial wall thickening improved.
