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
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.[2]
