Diagnosis of congenital aneurysmal giant right auricle in a dog

Abstract

A five-year-old intact male Golden Retriever was sent to our center for a second cardiac evaluation after the diagnosis of right atrial dilatation. Transthoracic and transesophageal echocardiographic evaluation and echo-contrast study were performed. A diagnosis of aneurysmal right auricle was issued without any sign of other cardiac pathologies. The tomographic evaluation was necessary to estimate the dimension of the aneurysmal area and exclude pericardial defects that may justify this anomaly. This report describes a rare case of aneurysmal giant right auricle in dogs. The diagnosis is accurate with the association of echocardiography and computed tomography.
