We report a case of focal tuberculous involvement of the posterior margin of the calcaneus with preservation of the articular margin. The route of infection was direct extension through tuberculous retrocalcaneal bursitis, a rare and atypical pathogenesis. Magnetic resonance imaging was helpful in ruling out neoplasm and in limiting the diagnosis to an inflammatory infectious process. (J Am Podiatr Med Assoc 95(3): 285–290, 2005)
