Abstract

The authors describe a case of intracranial vascular calcifications that mimicked small saccular aneurysms on CT angiography (CTA). The density of two vascular calcifications was visually similar to that of contrast in the parent vessel, making them indistinguishable from aneurysmal outpouchings. Comparison of the CTA with the non-contrast head CT (NCCT) was critical to distinguish low-density calcifications from tiny aneurysms.
