What is lung hepatization?

Pulmonary hepatisation refers to the pathologic alteration of lung tissue such that it resembles liver tissue. The term originates as a classic descriptor in surgical pathology, used to describe intermediate stages of lobar pneumonic consolidation. In imaging, the term is similarly used to describe lung consolidation.

The stage of red hepatization (2-3 d), so called because of its similarity to the consistency of liver, is characterized by the presence of many erythrocytes, neutrophils, desquamated epithelial cells, and fibrin within the alveoli.

What happens Gray hepatization?

Grey Hepatization The lungs will appear to be a grayish brown or yellow color because of the disintegration of red cells. Your lungs will also appear to be paler and drier than usual. There will be a persistence of fibrin exudate during this stage.

What is GREY hepatization in pneumonia?

Grey hepatization/late consolidation occurs 2 to 3 days following red hepatization and lasts for 4 to 8 days. The lung appears gray with liver-like consistency due to fibrinopurulent exudate, progressive disintegration of red blood cells, and hemosiderin. The macrophages begin to appear.

What is Hepatized?

Medical Definition of hepatization : conversion of tissue (as of the lungs in pneumonia) into a substance which resembles liver tissue and may become solidified.

Stage 4 (resolution) is the final recovery stage and occurs during days 8 to 10. Fluids and breakdown products from cell destruction are reabsorbed.

What is red Hepatization?

Red hepatization is when there are red blood cells, neutrophils, and fibrin in the pulmonary alveolus/ alveoli; it precedes gray hepatization, where the red cells have been broken down leaving a fibrinosuppurative exudate. The main cause is lobar pneumonia.
