| Discussion | 해설: There are multiple rim-enhancing lesions in the bilateral cerebral hemispheres and cerebellum. Some lesions have “target” appearance, which is highly suggestive of toxoplasmosis. Toxoplasmosis is the most common opportunistic infection and overall cause of a mass lesion in patients with HIV/AIDS. CNS toxoplasmosis most commonly involves the basal ganglia, thalami, corticomedullary junctions, and cerebellum. Multifocal lesions are more common than solitary ones. Alternating concentric zones of hyper- and hypointensity with marked perilesional edema are seen on T2WI. A ring-shaped zone of peripheral enhancement with a small eccentric mural nodule represents the "eccentric target" sign. |
