CTICasesPulmonary Tuberculosis mimicking Lung Cancer
Imaging findings
Chest CT shows a hot, FDG-avid speculated lung mass with tree-in-bud and centrilobular satellite nodules in the adjacent lung parenchyma. Biopsy and DNA probe confirmed Mycobacterium tuberculosis.
Key takeaways
Pulmonary tuberculosis can present as a solitary, speculated mass mimicking primary bronchogenic carcinoma on imaging and PET. The presence of tree-in-bud or centrilobular satellite nodules is a key clue favoring an infectious/granulomatous process.
