AbstractBackground: Isolated tuberculosis of any joint is a rare entity and often mimics other conditions. Thus, diagnosis and timely treatment is often delayed in these cases. Clinical case: We here report a unique case of tuberculosis of synovial tissue of ankle in a 46 year old female. She had suffered progressive left ankle swelling for ten years and left lower limb weight bearing difficulty since last 2 years prior to the presentation. She was not having past or contact history of tuberculosis. She was not having constitutional symptoms or any evidence of pulmonary tuberculosis. The diagnosis was confirmed by MRI study of the joint and typical histopathological findings of trucut biopsy from the thickened synovium. Relevant literature pertaining to tubercular arthritis has also been reviewed at length.
