Tuberculosis is a major health issue in developing countries. It remains a major international problem despite recent advances in radiological diagnosis and anti tubercular therapy. Tubercular osteomyelitis involving primarily the diaphysis without articular involvement is very rare. The nonspecific nature of the symptoms leads to a delay in the diagnosis. Radiographs may mimic pyogenic osteomyelitis, Brodie’s abscess, tumours or granulomatous lesions. Curettage of the lesion and the histopathological examination of the material obtained are necessary for confirmation of the diagnosis and offer a chance for early healing. We present a case of 23 year old immunocompetent male patient who presented to us with isolated diaphyseal involvement of radius with healed sinus.
