Abstract
A black hole (BH) is defined as any abnormal hypointensity as compared with normal-appearing white matter visible on T1-weighted sequences concordant with a region of high signal intensity on T2-weighted images. Black holes are considered to be acute when they coincide with a contrast enhancing lesion (CEL), and to be chronic or persistent when no corresponding CEL exists (Bagnato et al. 2003).
