To our knowledge, this is the 11th reported case of contrast agent extravasation from a ruptured intracranial aneurysm during angiography and the first during brachial arteriography. The patient, an 84-year-old woman, was in good condition at the time of the roentgenographic examination though she had suffered three episodes of subarachnoid bleeding more than a week earlier. The films showed filling of the ventricles by contrast agent extravasating from a ruptured anterior communicating aneurysm. The angiographic procedure could have contributed to the aneurysmal rebleed.
