Fluid-attenuated inversion-recovery imaging of cerebral infarction associated with tuberculous meningitis.
A 12-month-old girl presented with fever and vomiting. Cerebrospinal fluid (CSF) examination revealed an increase of mononuclear cells and Mycobacterium tuberculosis. Magnetic resonance imaging (MRI) taken two months after the onset showed cerebral infarction in the left basal ganglia, tuberculoma in the interpeduncular cistern and brain atrophy. The infarction was shown as central cystic lesions with surrounding hyperintensity in the fluid-attenuated inversion-recovery (FLAIR) image. The cystic lesions were not differentiated from surrounding lesions in T2 weighted image (T2WI) because both lesions were demonstrated as hyperintensity areas. The hyperintensity lesion shown in FLAIR image may indicate border zone encephalitis. The FLAIR image is more useful than T1 or T2WI to detect the extension of the infarcted area and circumscribed change.
