The authors presented an unusual case of an occipital artery aneurysm which developed spontaneously. The patient was a 41-year-old woman who suffered from the sudden onset of right hemiparesis and slurred speech. Computerized tomography scans of the brain demonstrated an intracerebral hemorrhage in the left parietal lobe. The carotid angiography revealed an incidental saccular aneurysm in the left occipital artery. The aneurysm was not treated because the patient's relatives refused operation and there were no subjective complaints by the patient. Certain particularities of this lesion are discussed in the context of the literature.
