Case summary

A 46-year-old female presented with migraines and an incidental 6.3mm x 3.9mm x 4.8mm left ophthalmic aneurysm with a wide neck.

Image observation

On the supplied views, a saccular outpouching appears at the ophthalmic segment of the internal carotid artery, with the vessel course appearing patent.

Model-generated clinical rationale

The assigned recommendation of coil embolization alone is supported by the aneurysm's relatively small dimensions. However, the documented wide neck morphology typically challenges coil stability, suggesting that the lack of a stent may be a limiting factor for this approach.

Model uncertainty

The OOF score distribution was diffuse: Coil embolization alone ranked first, but Stent-assisted coil embolization remained a material alternative.

Clinical uncertainty / missing factor

The most significant missing decision factor is the precise neck-to-dome ratio and the exact relationship of the ophthalmic artery origin to the aneurysm neck.
