hepatization

hepatization /hep·a·ti·za·tion/ (hep″ah-tĭ-za´shun) consolidation of tissue into a liverlike mass, as in the lung in lobar pneumonia. The early stage, in which pulmonary exudate is blood stained, is called red h. The later stage, in which red cells disintegrate and a fibrinosuppurative exudate persists, is called gray h.

hepatization

[hep′ətīzā′shən]

Etymology: Gk, hepatizein, like the liver

transformation of lung tissue into a solid mass resembling the liver, as in early pneumococcal pneumonia, in which consolidation and effusion of red blood cells in the alveoli produce red hepatization. In later stages of pneumococcal pneumonia, when white blood cells fill the alveoli, the consolidation becomes gray hepatization, or yellow hepatization, when infiltrated by fat deposits.

consolidation of tissue into a liverlike mass, especially as occurs in the lung in lobar pneumonia. The early stage, in which the pulmonary exudate is blood stained, is called red hepatization.

hepatization

transformation into a liverlike mass, especially the solidified state of the lung in lobar pneumonia. The early stage, in which the pulmonary exudate is blood-stained, is called red hepatization. The later stage, in which the red cells disintegrate and a fibrinosuppurative exudate persists, is called gray hepatization.

hepatization

Pulmonology The transformation of a tissue that is normally fluffy to one with a liver-like consistency, classically described as acquired firmness of lungs, commonly seen in lobar pneumonia–LP, especially if caused by S pneumoniae types 1, 3, 7 and 2, as well as other streptococci, Klebsiella spp, staphylococci and gram-negative rods; hepatization occurs primarily in the elderly and infants
