ABSTRACT

Diagnosis: Berry Aneurysm

History: 68 y.o. woman with 6 months of daily frontal headaches.

Findings: CT: There is a berry aneurysm arising from the supraclinoid portion of the left internal carotid artery, measuring 16 mm AP x 13.5 mm CC x12 mm LAT with a 5-mm neck. The aneurysm projects medially and inferiorly from its origin and encroaches on the optic chiasm and pituitary fossa. The pituitary infundibulum may be displaced posteriorly. MR: The ventricles are the upper limits of normal in size. There is a mixed but primarily hypointense signal foci in the parasellar region to the left of midline superimposed over the sella. On T2WI this has a hypointense signal similar to the signal void of the vesicle. MR (T1W-Gd) shows enhancement. MRA of the circle of Willis shows a flow void component and a central heterogeneous hyperintense signal component.

Ddx: • Congenital berry aneurysm • Atherosclerotic fusiform aneurysm • Mycotic aneurysm

Dxhow: Angiography at coiling.

Exam: Non-focal neurological exam.

No MeSH data available.
