What type of necrosis results from ischemia of neurons and glial cells?

The type of necrosis from the ischemia (loss of blood supply) of neurons and glial cells is liquefactive necrosis. Liquefactive necrosis is characterized by loss of tissue structure grossly and microscopically and only fragments of cells as well as neutrophilic (if acute) or lymphocytic (if chronic) cells. Liquefactive necrosis occurs only in the brain and in suppurative processes such as abscesses.

Other types of necrosis include coagulation necrosis (tissue structure is preserved), gangrenous necrosis (transmural necrosis), enzymatic fat necrosis (in breast tissue and pancreas), and fibrinolytic necrosis (in blood vessels).

The type of necrosis that typically results from ischemia of neurons and glial cells is liquefactive necrosis. Ischemia is an inadequate supply or blood, which causes neurons and glial cells to die. The dead neurons and glial cells result in the tissues becoming a liquid mass, hence the name liquefactive necrosis.
