Complete Pelvic Mass Regression FollowingTuberculosis Treatment as Indicated byF18-FDG PET/CT

Abstract

A 19-year-old woman with a history of tuberculosis (TB) in her family presented to theinfectious disease clinic of our hospital with right flank pain, nausea, vomiting, a 10- kg weight loss, and decreased urine volume for the past two months. Empirical anti-TBtreatment was initiated due to her family history of tuberculosis, a positive purified proteinderivative skin test, and the presence of a nodule in the posterobasal segment of the lungupon F18-FDG PET/CT. We aimed to present the complete regression of a pelvic mass lesionafter empirical tuberculosis treatment that was visualized on follow-up F18-FDG PET/CTimaging and discuss its contribution to the literature. F18-FDG PET/CT imaging follow up may offer an invaluable resource for monitoring extrapulmonary involvement of TB infected patients. The F18-FDG PET/CT imaging method may also contribute to the follow up of granulomatous and inflammatory diseases.
