Findings:
An approximately 3 mm measuring infra-ophthalmic right cavernous ICA aneurysm is seen on the right.
There is also subtle protuberance at the infero-lateral aspect of the left internal carotid artery in a similar location, suspicious for a further (albeit smaller) aneurysm.
4.5 mm measuring right lateral type MbifA with neck dimension of approximately 1 mm, as well as approximately 6 x 5.5 mm measuring left lateral type MbifA with neck dimension of 4 mm.
Absent anterior communicating artery.
There is a small berry aneurysm projecting medially from the right A1 segment, measuring approximately 2.5 x 2 mm.
Additionally, a superiorly protecting 3 mm aneurysm is noted arising from the right pericallosal artery. Second, smaller outpouching of the right pericallosal artery, suspicious of a second smaller pericallosal aneurysm.
No hydrocephalus or midline shift.
The orbits, paranasal sinuses and mastoid air cells are clear.
No bony abnormality is seen.
Conclusion:
Multiple, incidental intracranial aneurysms (bilateral infra-ophthalmic ICA, bilateral MbifA, right A1-aneurysm and right pericallosal aneurysms), as described above. Referral to neurovascular MDT is advised.
