Renal infarction is a rare disease which must be considered in any case of low back pain. The most frequent causes are related to emboligenic heart disease, renal artery fibrodysplasia or trauma. The authors report the second published case of idiopathic renal infarction. The diagnosis is usually suggested by contrast-enhanced abdominal CT scan, but is confirmed and refined by selective renal arteriography or CT angiography. Treatment may be medical or surgical depending on the severity of the lesions and the patient's general state. The therapeutic indications are discussed in the light of a review of the literature.

Renal infarction usually occurs in patients with severe atherosclerosis or heart disease. We report a 68-year-old lady who presented with total occlusion of the left renal artery of acute onset. Detailed work up did not reveal any specific cause and the infarction was considered to be idiopathic. The patient presented two-and-half years later with atrial fibrillation, which was managed with anti-arrhythmic drugs. Retrospectively, we believe that the cause of renal infarction was embolization secondary to paroxysmal atrial fibrillation. She is doing well on anti-coagulants and anti-arrhythmic drugs and was maintaining sinus rhythm when last seen.

Renal infarction usually occurs against a background of heart disease or a thromboembolic tendency and rarely is associated with infections. Here we present a case of a young boy who reported with painless gross hematuria following primary Varicella infection and was found to have an isolated renal infarct.

Renal infarction is a rare cause of referral to the emergency department, with very low estimated incidence (0.004%-0.007%). Usually, it manifests in patients aged 60-70 with risk factors for thromboembolism, mostly related to heart disease, atrial fibrillation in particular. We report a case of idiopathic segmental renal infarction in a 38-year-old patient, presenting with acute abdominal pain with no previous known history or risk factors for thromboembolic diseases. Because of its aspecific clinical presentation, this condition can mimic more frequent pathologies including pyelonephritis, nephrolithiasis, or as in our case appendicitis. Here we highlight the extremely ambiguous presentation of renal infarct and the importance for clinicians to be aware of this condition, particularly in patients without clear risk factors, as it usually has a good prognosis after appropriate anticoagulant therapy.
