- involve the basal leptomeninges.
- CT shows -
- obliteration of the basal cisterns by isodense or slightly hyperdense exudate, which shows diffuse enhancement with IV contrast medium
- The most useful CT criteria of abnormal basal meningeal enhancement are:
- (A) linear enhancement of the middle cerebral artery cisterns;
- (B) obliteration by contrast of the CSF spaces around normal vascular enhancement;
- (C) Y-shaped enhancement at the junction of the suprasellar and middle cerebral artery cisterns and
- (D) asymmetry of enhancement
- MRI depicts the basal meningeal enhancement, hydrocephalus and basal ganglia infarcts with greater sensitivity than CT
- Late sequelae of tuberculous meningitis include hydrocephalus, infarction, syringobulbia, and syringomyelia.Abnormal mri brain Tuberculous meningitis.
