Case Report

On sectioning of an organ from a 60-year-old man at the time of autopsy, a focal, wedge-shaped area that is firm is accompanied by extensive hemorrhage, giving it a red appearance. The lesion has a base on the surface of the organ. In which of the following situations will this lesion most likely occur?

A Lung with pulmonary thromboembolism

B Heart with coronary thrombosis

C Liver with hypovolemic shock

D Kidney with septic embolus

E Spleen with embolized mural thrombus

F Brain with cerebral arterial aneurysm

Answer & Explanation:

The bronchial arterial supply to the lung does not provide enough oxygenation to prevent infarction, but does provide blood to make the infarct hemorrhagic.
