CTICasesPulmonary Tuberculosis in a liver transplant recipient
Imaging findings
Serial CT scans over one year in a liver transplant recipient show progressive development of centrilobular nodules, tree-in-bud opacity, and pleural-based nodules in the left upper lobe, which grew Mycobacterium tuberculosis.
Key takeaways
Immunosuppressed patients are at high risk for reactivation of tuberculosis. On CT, this presents with a mixture of bronchogenic spread (tree-in-bud nodules) and lymphatic/pleural involvement, requiring a high index of suspicion.
