TB shoulder joint- A 30-year-old male presented with chronic pain in right shoulder. Plain radiograph of shoulder (A) reveals few lytic areas and marginal erosions at head of humerus and inferior margin of glenoid (arrows). On MRI-Coronal T1 (B), sagittal T2 (C) and coronal STIR (D) and post-contrast coronal (E, F) images show altered signal intensity areas appearing hypointense on T1, hyperintense on T2/STIR images with smooth peripheral enhancement and central non-enhancing areas suggestive of bone erosions seen involving head of humerus (arrow) and inferior aspect of glenoid (dotted arrow), with cortical irregularity of articular surfaces. Thick and enhancing synovium (thick arrow) with adjacent inflammatory changes. Findings suggestive of infective aetiology likely tubercular. On follow-up after 3 months of ATT, clinical improvement was seen
