[摘要] In this case report we describe an occasional finding of intrathoracic caudate lobe protruding through the diaphragm foramen in a 73-year-old woman who came to our attention for a screening for coronary artery disease, due to the presence of cardiovascular risk. The patient had no symptoms. The computed tomography showed, a circumscribed homogeneous soft tissue mass that protruding through the aortic diaphragmatic foramen that was as isodense as the liver. Moreover was revealed an abnormal artery emerging from the celiac tripod which, through the diaphragmatic foramen, ends in an inferior pulmonary vein creating an arteriovenous malformation.
