18F-FDG PET/CT imaging and curative effect evaluation of multiple muscular tuberculosis.

Abstract

Tuberculosis continues to be a significant global health concern, impacting various parts of the body aside from the lungs. Muscular tuberculosis (MT), while rare, poses diagnostic hurdles due to its nonspecific imaging features. Presenting a case of a 66-year-old man with multiple MT lesions, we underscore the vital contribution of positron emission tomography/computed tomography (PET/CT) in both diagnosis and treatment assessment. Fluorine-18-fluorodeoxyglucose (¹⁸F-FDG) PET/CT imaging revealed hypermetabolism in bilateral chest and back muscles, facilitating accurate diagnosis and monitoring treatment response. This highlights the pivotal role of ¹⁸F-FDG PET/CT in managing MT, especially in cases with multiple lesions.
