title: A rare case of spontaneous true aneurysm of the occipital artery.
abstract: A 51-year-old man presented with a pulsatile scalp mass over the right occipital region, which had increased in size over the previous 1 month. He had no previous history of head trauma. Three-dimensional computed tomography (3D-CT) angiography of the brain revealed a 3.0 x 1.5 cm occipital artery aneurysm arising from the occipital artery. The occipital artery aneurysm was removed following the ligation of the proximal and distal portion of the occipital artery aneurysm. The histological diagnosis was true aneurysm. To the best of our knowledge, this is the first reported case in the literature.
