Aneurysm of a persistent sciatic artery.
We report a case of an aneurysm of a persistent sciatic artery which caused buttock pain. Preoperative diagnosis is very difficult. However, awareness of the presence of this rare embryonic abnormality is important, especially in elderly persons with atherosclerotic changes. Sagittal magnetic resonance imaging (MRI) was very useful in reaching this diagnosis.
