Overwiew
MRI is used for the assessment of extrapulmonary tuberculosis, such as CNS tuberculosis, Pott's disease, and parotid gland tuberculosis.
MRI
CNS Tuberculosis
- MRI is most commonly used in cases of CNS infection with tuberculosis.
- The following findings may be seen in CNS tuberculosis:[1]
- Ring-enhancing mass in T2 and hypodense lesion in case of a non-caseating tuberculoma.
- A caseating tuberculoma is seen as a hypodense lesion in both T1 and T2.
- Cerebral edema
- Diffuse enhancement in case of meningitis
Pott's Disease
- Spinal MRI is the image diagnostic test of choice for spinal tuberculosis.
- Findings include: [2]
- Endplate irregularity
- Irregular anterior aspect of the vertebral bodies
- Edema and enhancement of the bone marrow.
- Destruction of vertebral body in severe cases.
Osteoarticular Tuberculosis
- MRI findings in osteoarticular tuberculosis include:[3]
- Demineralization
- Narrowing of the joint space
- Bone and cartilage erosion
- Calcifications
Parotid Gland Tuberculosis
- Tuberculosis infection of the parotid gland con mimic a parotid neoplasm.
- The MRI shown below reveals a well-defined mass lesion, measuring 16 × 21 × 30 mm in size, hypointense on T1-weighted images, and hyperintense on T2-weighted images with homogenous contrast enhancement, located in the posterior part of the superficial lobe of the right parotid gland.[4]
