Two cases with renal infarction diagnosed in the early course using contrast-enhanced CT.
We experienced two cases of renal infarction with atrial fibrillation who presented with acute abdominal pain. On initial urinalysis, both patients showed no hematuria, but the plasma lactate dehydrogenase level was markedly elevated with little or no rise in plasma transaminases. Their diagnosis was confirmed by contrast-enhanced CT of the abdomen on the second and third days of the crisis. We immediately initiated anticoagulant therapy, resulting in successful prevention of new embolism. Contrast-enhanced CT should be considered if abdominal symptoms develop in patients with atrial fibrillation. Renal infarction could be diagnosed in the early course, even in cases with incomplete occlusion of the renal arteries and normal renal function.
