RESUMO
Interrupted aortic arch is a rare and usually lethal malformation, representing approximately 1% of congenital heart disease. This presents as a missing segment of the aortic arch and is divided into three types: A-called extreme form of coarctation, and is characterized by disruption of aorta's continuity distal to the left subclavian artery (30-40%), B-disruption between the left subclavian and the left carotid arteries (55-60%), and C-the most uncommon type, interruption proximal to the left common carotid artery. The suspicion of coarctation of the aorta can be made from a combination of physical findings including systolic ejection murmur, the murmurs of collateral blood vessels, diminished or absent femoral pulse, and difference in blood pressure between arms and legs. Interrupted aortic arch is an extremely rare anomaly in adult patients. To our knowledge, the world medical literature contains only about 13 reports of interrupted aortic arch diagnosed in adults.

A case of a 50-year-old female with hypertension and diabetes, admitted to the hospital due to echocardiographically detected left atrial tumour, is presented. Differential diagnosis included thrombus, myxoma and infectious tumour. The patient underwent surgery. Histopathological examination revealed the presence of an abscess in the left atrium. This report underlines the difficulties in the diagnosis of cardiac tumours.
