It is important to consider foot and ankle tuberculosis (TB) as a potential cause of cystic lesion around the ankle, especially in patients with a history of TB. Early diagnosis and treatment with a rifampin-based regimen for a duration of 12 months can lead to good functional and clinical outcomes.
Foot and ankle TB is rarest form of skeletal TB. It’s symptoms may
present slowly over an extended period of time, making a diagnosis
difficult. For the best outcome and to reduce the risk of deformity
diagnosis must be early. The treatment is 12 months rifampin-based
regimen for drug-susceptible TB.
