Mirror aneurysms of extracranial internal carotid arteries in a patient with beta-thalassemia major.

Beta-thalassemia major is a chronic disorder characterised by severe anemia. This patient with beta-thalassemia major is the first magnetic resonance (MR) angiographic case for symmetric mirror aneurysms of the extracranial internal carotid arteries. For diagnosis of vascular complications requires angiographic procedures such as catheter angiography, computed tomography angiography, MR angiography, or Doppler ultrasonography. Time-of-flight MR angiography is a non-invasive useful technique in diagnosis of the aneurysmatic patients.
