Complete Pelvic Mass Regression Following Tuberculosis Treatment as Indicated by F18-FDG PET/CT

This work is licensed under a Creative Commons Attribution-Non Commercial 4.0 International License. ABSTRACT A 19-year-old woman with a history of tuberculosis (TB) in her family presented to the infectious disease clinic of our hospital with right flank pain, nausea, vomiting, a 10kg weight loss, and decreased urine volume for the past two months. Empirical anti-TB treatment was initiated due to her family history of tuberculosis, a positive purified protein derivative skin test, and the presence of a nodule in the posterobasal segment of the lung upon F18-FDG PET/CT. We aimed to present the complete regression of a pelvic mass lesion after empirical tuberculosis treatment that was visualized on follow-up F18-FDG PET/CT imaging and discuss its contribution to the literature. F18-FDG PET/CT imaging followup may offer an invaluable resource for monitoring extrapulmonary involvement of TBinfected patients. The F18-FDG PET/CT imaging method may also contribute to the followup of granulomatous and inflammatory diseases.
