Spontaneous regression of a giant basilar artery aneurysm in a young adult after surgical injury: case report and literature review

A giant basilar artery aneurysm of young woman with endocrine disturbance was misdiagnosed as a large pituitary adenoma and treated surgically via a trans-sphenoidal approach was planned. But the neurosurgery was finally aborted because of massive bleeding during the procedure. One year later, a cerebral angiography confirmed this basilar artery aneurysm was obviously regressed and then endovascular coiling was successfully performed. No neurological complication occurred post-procedure and the endocrine dysfunction symptom was obviously improved. (authors)
