| brain 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) |

| varicose aneurysm | A blood-containing sac, communicating with both an artery and a vein. (05 Mar 2000) |
| vein of galen aneurysm | <radiology> Really AVM, not aneurysm, AVM of posterior choroidal branches of PCA, with or without congestive heart failure due to AV shunting (left to right), predominantly right-sided cardiomegaly, wide superior mediastinum, retrosternal fullness, cervical trachea displaced anteriorly (12 Dec 1998) |
| Rasmussen's aneurysm | Aneurysmal dilation of a branch of a pulmonary artery in a tuberculous cavity, rupture of which may cause serious haemoptysis. Aneurysm of the right ventricle or right ventricular outflow patch, aneurysm occurring after right ventriculostomy; the aneurysm may either be a false or a true aneurysm. (05 Mar 2000) |

| 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) |
