Ring Enhancing Lesion - MRI Brain in AIDS

RING ENHANCING LESION :: BRAIN MRI - AIDS

Few points of differentiation

TB VS NEUROCYSTICERCOSIS

1. TB is usually >20mm, irregular outlined rim enhancing lesion with significant edema and mass effect.

Whereas NCC is <20mm, regular outlined, without mass effect.

2. TOXOPLASMOSIS which becomes an important DD especially in AIDS patients, which occurs mostly in Basal Ganglia region, usually shows microhemorrhages in SWI.

3. Lymphoma because of it's cellularity can be T2 hypointense and may show diffusion restriction, and can show ring enhancement in immunocompromised
