Multifocal skeletal tuberculosis.

Multifocal skeletal tuberculosis is defined as osteoarticular lesions that occur simultaneously at two or more locations. We present radiologic findings in two cases of multifocal osteoarticular tuberculosis. Differential diagnoses of such lesions, based on different radiologic modalities, can include metastatic disease, eosinophilic granuloma, or lymphoma. Since tuberculosis can be present in multiple sites, especially in patients from areas where tuberculosis is endemic, it is essential to avoid a delay in diagnosis.
