Sulcal effacement is the term used to describe the loss of the normal gyral-sulcal pattern of the brain, which is typically associated with raised intracranial pressure. Stroke occurs when decreased blood flow to the brain results in cell death (infarct/necrosis) There are two main types of stroke: ischemic (most common) due to lack of blood flow from thrombosis, embolism, systemic hypoperfusion, or cerebral venous sinus thrombosis, and hemorrhagic, due to bleeding.
