| cerebral aneurysm | A dilated and weakened portion of a cerebral blood vessel that is prone to rupture. A cerebral aneurysm may occur as a birth defect or develop as the result of long-standing poorly controlled hypertension. Symptoms of a ruptured cerebral aneurysm include a sudden, severe thunderclap headache that may be associated with nausea, vomiting and a decreased level of consciousness. (27 Sep 1997) |

| Charcot-Bouchard aneurysm | Dilatation in the diameter of small arteries and arterioles secondary to lipohyalinosis from long-standing hypertension associated with intracerebral haematomas. Synonym: Charcot-Bouchard aneurysm. (05 Mar 2000) |
| peripheral aneurysm | A saclike aneurysm springing from one side of an artery, an aneurysm of one of the smaller branches of an artery. (05 Mar 2000) |
| phantom aneurysm | A palpable throbbing aorta, mistaken by novices for an aneurysm. (05 Mar 2000) |
| ruptured aneurysm | An aneurysm that is haemorrhaging into its wall or surrounding tissues. (05 Mar 2000) |
| cirsoid aneurysm | Dilation of a group of blood vessels owing to congenital malformation with arteriovenous shunting. Synonym: cirsoid varix, racemose aneurysm, racemose haemangioma. (05 Mar 2000) |
| miliary aneurysm | Dilatation in the diameter of small arteries and arterioles secondary to lipohyalinosis from long-standing hypertension associated with intracerebral haematomas. Synonym: Charcot-Bouchard aneurysm. (05 Mar 2000) |
