Abstract

Acute renal infarction is a rare and frequently misdiagnosed condition that often presents with nonspecific abdominal or left flank pain. Renal infarction is commonly associated with cardioembolic etiologies, making echocardiography evaluation essential. In the case presented, a 60-year-old male had presented with a sudden onset of left flank pain, and a computed tomography (CT) confirmed renal infarction. A transthoracic echocardiogram was performed to assess cardiac structures, function, and potential intracardiac thrombus. Results showed the diagnosis of moderately reduced left ventricular systolic dysfunction with exclusion of a cardioembolic source, timely investigation of anticoagulant therapy, and a reduced risk of irreversible damage. Echocardiography plays a critical role in narrowing the differential diagnosis and supporting timely management decisions, particularly because delays in diagnosis can cause irreversible damage. A transthoracic echocardiogram is a valuable and important adjunct to CT in evaluating renal infarction.
