Choroidal aneurysm of the brain

Choroidal aneurysm of the brain is like any other kind of aneurysm wherein there is a ballooning out of the wall of an artery.  This kind of aneurysm is found in the brain, at the choroidal artery in particular.  The choroidal artery is an important part the cerebral artery which originates in the internal carotid or middle artery, with supplies blood to the optic tract, the posterior limb of the internal capsule, the cerebral peduncle, and the choroids plexus. It has been noted that this kind of disorder account for 2 to 5 % of all intracranial aneurysms (Cho, Kim, Chang, Kim, Kim, & Choi, 2008).  Aneurysm usually takes place when a slight break or weakness in the muscular layer of an artery allows the pressure of the blood to push the walls of the blood vessels out.  The larger the bulge, the thinner the arterial wall becomes.  Eventually the wall gives way and a hemorrhage occurs (Keir, Wise, & Kerbs, 2002)

The classic presentation of this disease is a sudden onset of severe headache.  This is usually accompanied by nausea and voting and nuchal rigidity ( Moore, & Newell, 2005)

Consciousness is frequently altered, with confusion and lethargy may also occur.  Some may even undergo loss of consciousness and coma.  Some patients also experience electrolyte disturbance, retinal and pre-retinal hemorrhages, meningism and photophobia, however both the last two symptoms are very rare.

Usually, there is not only one way to treat an aneurysm.  The right treatment depends on the skill and experience of the team (Cognard, & Forsting, 2005).  However, the management of choroidal brain aneurysm usually consists of determining the extent of the aneurysm and finding the appropriate treatment for the patient’s condition using CT scans, MRI Imaging, and angiography.  Some of the most common treatment, on the other hand, includes endovascular treatment, surgery, and coil-embolisation angiography.
