Association of Intracranial Aneurysms with Meningiomas, Pituitary Adenomas, and Gliomas: Review of Possible Interrelationships

Figure 2

Incidence of asymptomatic aneurysm alone versus concurrence of asymptomatic aneurysm with symptomatic brain tumor. The percentage of subjects with aneurysm is plotted for references that provide total count statistics. The percentage of subjects with asymptomatic aneurysm alone (white bars) is similar to the percentage of subjects with asymptomatic aneurysm concurrent with brain tumor (meningioma, blue bar), with the exception of pituitary tumor with acromegaly (green bar [6]), which is approximately 4 times the upper limit of the former. References are provided in brackets.
