Figure 1. MRI brain sagittal angiogram shows presence of a large patent aneurysm of size 2 x 1.5 x 1.6 cm arising from supraclinoid portion of left internal carotid artery (ICA) at its bifurcation. Neck of the aneurysm is wide and measuring approx. 6 mm.
Figure 2. MRI coronal angiogram shows presence of a large saccular aneurysm of size 2 x 1.5 x 1.6 cm arising from supraclinoid portion of left internal carotid artery at its bifurcation.
Figure 3. MRI brain axial angiogram view shows left middle cerebral artery (MCA) is arising adjacent to aneurysm and aneurysm causing compression over left MCA. Aneurysm causing compression over left-sided optic nerve and optic chiasma and left inferior frontal lobe. No evidence of any "tit" or irregularity within aneurysm.
Figure 4. MRI brain coronal angiogram shows left anterior cerebral artery is filled from right internal carotid artery by anterior communicating artery.
Diagnosis: Unruptured aneurysm in left internal carotid artery
MRI coronal angiogram shows presence of a large saccular aneurysm of size 2 Ã 1.5 Ã 1.6 cm arising from supraclinoid portion of left internal carotid artery at its bifurcation.
MRI brain coronal angiogram shows left anterior cerebral artery is filled from right internal carotid artery by anterior communicating artery.
An aneurysm is a bulge of an artery wall due to any cause.
In patients undergoing coronary angiography, incidental intracranial aneurysm was found in 5.6 % of cases.2
Diagnosis is made by CT angiography or MR angiography.
