急性肾梗死，属凝固性坏死，坏死区域呈楔形，是由于组织血供减少引起缺血，终而产生灰白的梗死区。有少量从肾包膜来的血液供应紧邻的皮质。髓质和余下的皮质呈充血状。
This is an acute renal infarction. Note the wedge shape of this zone of coagulative necrosis resulting from loss of blood supply with resultant tissue ischemia that produces the pale infarct. The small amount of blood supply from the capsule supplies the immediate subcortical zone. The remaining cortex is congested, as is the medulla.
