Tubercular dactylitis is an unusual form of skeletal tuberculosis. Radiographic features of cystic expansion of the short tubular bones have led to the name of "Spina Ventosa" for tuberculosis dactylitis of the short bones. We report here a case of a Spina Ventosa in a 15 year-old female, who presented with complaint of draining sinus on the dorsum of the third digit of the left foot.
