An unusual case of multiple intracranial aneurysms

A 49-year-old female patient with six intracranial aneurysms, all of which were treated successfully by direct surgery, is reported. She had a major subarachnoid haemorrhage 10 years ago. Because of difficulty in identifying the offending aneurysm she was not surgically treated at that time. The natural progression of intracranial aneurysms, the problem of identifying the lesion in a patient with multiple aneurysms, and an example of excellent recovery of visual function following surgical treatment are discussed.
