Abstract

Tuberculosis (TB) remains a significant public health problem in developing countries, but its diagnosis can be challenging as it may mimic malignancy or other granulomatous diseases. Although pulmonary TB is the most common form, TB can spread hematogenously, lymphatically, or by direct extension to any tissue or organ. We report a 62-year-old female who underwent 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) for malignancy evaluation, was diagnosed with extrapulmonary TB, and had her treatment response assessed with 18F-FDG PET/CT.
