Overview

MRI is indicated for the diagnosis of extra-pulmonary tuberculosis, such as CNS tuberculosis, parotid gland tuberculosis osteoarticular tuberculosis, and Pott's disease.

MRI

CNS Tuberculosis

  • Ring-enhancing mass in T2 and hypodense lesion in case of a non-caseating tuberculoma.
  • A caseating tuberculoma can show a hypodense lesion in both T1 and T2.
  • Cerebral edema
  • Diffuse enhancement in case of meningitis
