In most cases subsequent central caseous necro- sis develops which is at frst solid but may liquefy over time. Tuberculomas can afect the central nervous pa- renchyma in a disseminated fashion afecting both the brain and spine, or might be visualized as solitary le- sions. In adults the tuberculoma is most ofen found in the frontal or parietal lobes, pre- dominantly situated at the corticomedullary junction. A homogeneous contrast enhancement of the le- sion is the hallmark for non-caseating granuloma for both imaging modalities. On the contrary, the caseating granuloma will display a strong ring-like enhancement Fig. If the centre of the caseating granuloma is solid, it is iso- or hypointense to normal brain tissue on T1-weighted and T2-weighted images, and might enhance het- may be recognized by the lack of meningo-vascular en- erogeneously.
