Given the paucity of cases and limited experience in diagnosis and management of the disease each case is a learning tool in itself. Case presentation We report the rare case of a 78-year-old Caucasian man who presented to a peripheral emergency department with chest pain and was subsequently found to have a giant right coronary artery aneurysm. Following initial investigation and treatment he was referred to our hospital for definitive management. Conclusion The case described illustrates one of the varied presentations and subsequent management of an ill-defined and heterogeneous disease process. Given the limited experience with giant aneurysms in the coronary circulation this case provides valuable insight into the clinical presentation of the disease and gives an example of the management of the most recent such case at our hospital. Introduction Coronary artery aneurysms are a relatively common entity. However giant aneurysms 2 cm diameter are rare 1 2 . Most are atherosclerotic in nature but the exact mechanism leading to the development of ectasia in these vessels is unknown. Evidence suggests that contributory factors include a combination of genetic predisposition common risk factors for coronary artery disease direct arterial wall damage and abnormal vessel wall metabolism 1-4 . The low-recorded incidence of these giant aneurysms means the clinical presentation and management of
