Spectrum of imaging findings in osteoarticular tuberculosis

Abstract

Abstract Background Tuberculosis (TB) is still a major public health problem. It is endemic in most of the developing countries. Osteoarticular tuberculosis is an uncommon infection, and its diagnosis is often missed due to non-specific clinical and imaging findings. Main body of abstract The diagnosis of osteoarticular TB is often delayed due to non-specific clinical presentation and often mimics with other infectious/inflammatory disorders. However, as the disease is curable, prompt diagnosis and early initiation of treatment remain critical to prevent the development of deformity and bone destruction. MRI is sensitive in early detection of articular and marrow abnormalities, detecting complications and assessing response to treatment. In this review, we describe the spectrum of various MR imaging findings of osteoarticular TB, which helps in early diagnosis and differentiating these from other pathologies with similar imaging appearances. These are described through case-based illustrations of different anatomical locations of osteoarticular TB. Short conclusion MR imaging is the emerging modality of choice for early diagnosis of osteoarticular tuberculosis and helps to differentiate it from other infective/inflammatory diseases.
