An 83-year-old woman presented with a lump on her left frontal region. One month ago, she fell and hit the ground with the left side of her head. However, she had no evidence of injury. After 10 days, a progressive, painless lump appeared where her head was injured. The lump was pulsatile, but it not obviously shrank subtly in size with compression of her left superficial temporal artery. The ultrasound examination in local hospital demonstrated a pseudoaneurysm. Head computed tomography showed an isodense subcutaneous lesion in her left frontal area. Further 3-dimensional reconstruction of contrast-enhanced computed tomography indicated an aneurysm from her left superficial temporal artery. The aneurysm was completely removed by surgery, and pathologic examination confirmed pseudoaneurysm. Because the pseudoaneurysm was large, the disadvantage of the endovascular treatment options could be a permanent lump. Our patient received a surgical resection without facial nerve damage.
