CT scan in the axial plane in a patient with flank pain shows a wedge-shaped swollen perfusion defect involving both the cortex and medulla of the left kidney and extending to the capsular surface. There is a hint of a capsular perfusion defect (cortical rim sign) .

CT in the nephrographic phase in the axial projection shows multiple scars in both kidneys. On the left there are 2 scars. The deeper scar goes down to the collecting system without a clubbed nor naked calyx, indicating that it Is likely of vascular origin. On the right side there are areas of cortical thinning and loss. The multicentric nature and presence of atherosclerotic disease in the aorta raises the possibility of cholesterol emboli as a cause of the infarctions

Patient presented with dyspnea and chest pain. A diagnosis of large pulmonary embolus with pulmonary infarction was made on CTPA. In addition, paradoxical emboli were identified in the aorta, right renal artery and right iliac artery. This image shows an embolus in the aorta and non-perfusion of the right kidney as a result embolic infarction

Sickle Cell Disease Microinfarcts and Enlarged Left Kidney
CT with contrast in the coronal plane in a 23-year-old male shows an enlarged left kidney measuring close to 13cms. with evidence of bilateral scarring attributed to microinfarcts from sickle cell disease. Note the stomach has taken up the space since the spleen was almost totally infarcted.
