Figure 1.
Pseudotumoral MS with typical lesions of BCS shows concentric lamellae (arrows), whereas more atypical Balo-like lesions display more complex shapes (head arrows): (A) T1W image shows hypointense lesions in the right frontal-parietal-temporal and left frontal, (B, C) lesions have a high signal intensity on T2W and FLAIR images, (D, E) lesions are unrestricted diffuse seen on the ADC image (asterisks). Note that the high signal intensity of lesions on the DWI image is an artifact due to T2 shine-through effect (curved arrows), and (F) a contrast-enhanced T1W image reveals a characteristic enhancement as a broken ring (arrows).
