Aneurysm of a persistent primitive olfactory artery

Case report

Restricted access

✓ A ruptured anterior cerebral artery (ACA) aneurysm is reported in a patient in whom an anomalous ACA arose from the internal carotid artery at the bifurcation. The aberrant artery coursed anteriorly along the ipsilateral olfactory tract and made a hairpin turn posterior to the olfactory bulb, supplying the circulation of the ACA. Persistence of the primitive olfactory artery is suggested as an embryological origin of this vascular anomaly.

    Left internal carotid angiograms revealing an aneurysm (thick arrow), with anterior (left), lateral (center), and right anterior oblique views (right). Anomalous anterior cerebral artery (arrowheads) originating from the left internal carotid artery at the bifurcation, running anteroinferiorly and making a hairpin turn posterior to the crista galli. Note the long anterior cerebral artery (fine arrow) and the right recurrent artery of Heubner (double arrows).

    Schematic drawing depicting the anomalous anterior cerebral artery (ACA) in this case. AChA = anterior choroidal artery; ACoA = anterior communicating artery; A-1 = ACA precommunicating segment; A-2 = ACA postcommunicating segment; CmA = callosomarginal arteries; ICA = internal carotid artery; MCA = middle cerebral artery; PCoA = posterior communicating artery; PericalA = pericallosal arteries.

    Schematic drawings showing development of an anterior cerebral artery (ACA) according to Padget6 in embryos from 9- to 43-mm crown-rump (CR) length (a to d). The recurrent artery is formed from the primitive olfactory artery (POA) or the components of the anastomosis between the POA and its collateral anterior cerebral branch. Possible explanations for a present anomaly (a and b, e and f). For details see text. AChA = anterior choroidal artery; ACoA = anterior communicating artery; ICA = internal carotid artery; MCA = middle cerebral artery; OA = ophthalmic artery; PCoA = posterior communicating artery; PDO = primitive dorsal ophthalmic artery; PVO = primitive ventral ophthalmic artery.
