title: Spontaneous regression of an aneurysm at a nonbranching site of the supraclinoid internal carotid artery. Case report.
abstract: The authors report on a patient who had presented with a subarachnoid hemorrhage whose bleeding source was not revealed on initial angiography, although subsequent studies disclosed a saccular aneurysm at a nonbranching site of the left internal carotid artery (ICA). The aneurysm could have been caused spontaneously or after blunt head trauma. The patient was supportively observed given the considerable risks associated with aggressive treatments. The present case represents the first involving spontaneous complete regression of an aneurysm at a nonbranching site of the supraclinoid ICA.
