A 35-year-old immuno-competent male with open pulmonary tuberculosis associated with extra-ordinary extensive extra-pulmonary tuberculosis.

Multifocal tuberculosis is characterized by the presence of large multifocal tuberculosis areas in the same or different adjacent or distant organs. Primary lesions are usually in the lungs in the majority of patients. Difficulty in confirming multifocal tuberculosis and consideration of other diseases may lead to a delay in diagnosis and thus in initiating treatment. Bone and joint involvement in tuberculosis is uncommon. While osteoarticular tuberculosis most commonly occurs in the vertebral column, less frequently affected sites are hip, knee, and sacroiliac joints. The following is a fascinating case of open pulmonary tuberculosis associated with extensive extra-pulmonary multifocal tuberculosis.
