Abstract

The term of "pedicle aneurysm" has been only cited in combination with the arteriovenous malformation (AVM). However, authors report a case with a pure pedicle aneurysm, which is not associated with AVM. A 29-year-old female patient presented with postpartum seizure and vomiting. Four days before, she delivered her second baby through Cesarean section. On admission, neuroimaging studies demonstrated the Fisher Grade II subarachnoid hemorrhage with a large round partially thrombosed supra- and retrosellar vascular mass. The subsequent magnetic resonance and cerebral angiography revealed a giant saccular aneurysmal sac which was fed by two pedicle arteries. Despite the intraoperative rupture, the aneurysm was completely obliterated via orbitozygomatic approach and the dural pedicle arteries were verified. On postoperative third day, hypothalamic ischemic infarction with moderate hemispheric brain swelling developed. She died on the 4th postoperative days . We report a special case of dual pedicle artery giant aneurysm supplied from the anterior and posterior cerebral circulation simultaneously.
