Introduction: Cardiac tumours are rare findings which can be manifested by different clinical features. Most of these tumours have similar imaging findings during the clinical work up of patients presenting with cardiac masses. Myxoma is a common tumour of the left atrium which also has less common differential diagnoses: haemangiomas and angiosarcomas. The final diagnosis of such atumouris made by pathology studies. However, in some cases, surgery to reveal the exact nature of the mass is not possible. Imaging procedures, such as trans-oesophageal echocardiography and cardiac magnetic resonance imaging (MRI), are considered reliable methods for excluding differential diagnoses. Case Presentation: In this report, we will discuss a case of a left atrial mass which was first diagnosed as myxoma in angiography. During further imaging work ups, a cardiac MRI assisted in determining the exact nature and location of the tumour. Conclusion: While myxoma is a common tumour of the left atrium, cardiologists should always consider haemangiomas as a differential diagnosis.
