Abstract
Intracranial tuberculosis in children is seen as either parenchymal tuberculous lesions or tuberculous meningitis (TBM). This article demonstrates the MR features of TBM and the two varieties of tuberculous (TB) granulomata. Gummatous granulomata (tuberculomata) comprise 90% of presenting intracranial TB lesions. They have a characteristic low signal on T2-weighted sequences that differentiates them from other commonly encountered ring-enhancing lesions such as neurocysticerci. TB abscesses are very rare and have the same features as pyogenic abscesses. Features of TBM include hydrocephalus, basal meningeal enhancement and basal ganglia infarctions.
Highlights
The Western Cape has one of the highest incidences of intracranial tubercu lous (TB) in the world
Tuberculomata comprise approximately 90% of intracranial TB lesions and are hypo intense on T2weighted sequences'? (Figure 1)
TB abscesses are relatively rare (Figure 2). They contain liquefied or caseous material that differentiates them from the gummatous material seen in tuberculomata
Summary
The Western Cape has one of the highest incidences of intracranial TB in the world. This may take the form of TBM where the patient presents with a decreased level of consciousness, cranial nerve palsies and hemiplegia.' In contrast, intracranial granulomata usually manifest with seizures.' This article demonstrates the MR imaging features of these forms of intracranial TB.
