Infarction of the lower pole of the right kidney mimicking acute appendicitis: A case report

AbstractRenal infarction is frequently misdiagnosed as other common diseases, such as urolithiasis, pyelonephritis, or intra-abdominal lesions, because of its rareness and nonspecific clinical presentation and laboratory findings. However, delayed diagnosis is associated with persistent clinical symptoms, risk of renal impairment, and even death. We report a 43-year-old man who was diagnosed with acute appendicitis initially as a result of right lower abdominal pain/tenderness with leukocytosis. Contrast enhanced computed tomography was done because of refractory pain and infarction of the lower pole of the right kidney infarction was found. Renal infarction should be included in the differential diagnosis of abdominal/flank pain, especially in those with risk factors such as atrial fibrillation, valvular heart disease and previous thromboembolic events
