MCQ IN MEDICINE

Detailed explanation-1: -The damage can be focal (confined to one area of the brain) or diffuse (happens in more than one area of the brain). The severity of a brain injury can range from a mild concussion to a severe injury that results in coma or even death.

Detailed explanation-2: -Multifocal: presence of multiple well-delineated invasive tumor foci separated from each other by uninvolved breast tissue, regardless of the distance between the foci; Diffuse: dispersed over a large area much like a spider’s web with no distinct tumor mass being evident.

Detailed explanation-3: -Focal and diffuse brain injury are ways to classify brain injury: focal injury occurs in a specific location, while diffuse injury occurs over a more widespread area.
