We report the imaging features of four cases with calcified intracranial aneurysm. All four patients underwentCT, CT angiography, MR, magnetic resonance angiography, and angiography. Calcification of the aneurysm wall wasclearly demonstrated with CT and CTA in all cases and with conventional angiography in one case. The shape ofcalcification was curvilinear in two cases and punctate in two. On MR, two curvilinear calcifications weredemonstrated as peripheral rim of signal void but two punctate calcifications were not shown.
