The kidney is cut in half along its longitudinal axis, exposing :
(A.) the cortex
(B.) the medulla
(C.) a minor calyx .
The pyramidal shaped infarct is pale as compared to the adjacent normal cortex. Why? as 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 arrow points to a line of hyperemia that represents the interface between normal and necrotic tissue.
2- Microscopic section of Renal infarction:
* The thick arrow points to glomerulus in an area of coagulation (ischemic) necrosis.
* The thin arrow points to a glomerulus which is in the interface between necrotic and normal kidney.
