Indeed, biology is seldom completely correctly described as dichotomic. There is some overlap between white and red infarcts: liver infarction is one example.
Liver infarctions are rare because of the liver’s dual blood supply and the hepatic sinusoid structure.
Acute occlusion of the hepatic artery is unusual but may occur as a result of embolism, polyarteritis nodosa, or accidental surgical ligation. In these settings irregular, pale areas – often surrounded be a hyperemic zone – reflect the causative ischemic necrosis.
