“…However, its identification is clinically important before carotid endarterectomy or skull base surgery. It might be associated with aneurysms, vascular malformations and atherosclerotic diseases 3,12,16 . Fenestrations of the cerebral arteries are vascular anomalies with a reported incidence as high as 11% 4 .…”

“…It is usually part of a large branch of the internal carotid that forms the basilar artery, and one or both vertebral arteries are frequently either hypoplastic or absent (Nakayama et al, 1970;Carbonin et al, 1976;Khodadad, 1977). A persistent hypoglossal artery may even be associated with an aneurysm (Kodama et al, 1976).…”

The early development of the hypoglossal nerve and occipital somites in staged human embryos

1984

Serial sections of 105 human embryos (including 20 silver preparations) from stage 11 (24 days) to stage 22 (54 days) were studied, and 23 graphic reconstructions were prepared. The hypoglossal nucleus is evident at stage 12 and becomes isolated from other efferent nuclei at stage 14. The first hypoglossal nerve fibers appear at stage 12. The roots unite at stage 14 and the main trunk arrives in the tongue at stage 15. Four occipital somites can be identified during stage 13, and the sclerotomic material forms two bilateral masses. The fourth sclerotome separates in stage 14 and develops like a vertebra. This and the remaining sclerotomic material form the basioccipital and exoccipital parts of the chondrocranium , which are the first to appear. Four occipital myotomes develop and grow towards the tongue as the "hypoglossal cord", which arrives prior to the hypoglossal nerve. The developmental similarity in the hypoglossal region between birds and mammals, combined with experimental studies in birds, renders it extremely likely that the hypoglossal musculature in mammals also is derived from occipital somites. The present study is the first in which this conclusion is adequately supported in the human. This investigation aids in the interpretation and timing of origin of variations (e.g., bipartite hypoglossal canal) and anomalies (e.g., persistent hypoglossal artery).

“…The persistent hypoglossal artery is commonly an incidental finding; however, it may be of clinical significance in some situations. Aneurysms occasionally develop at the junction of this artery with the basilar artery [10]. In the setting of carotid bifurcation disease, vertebral arterial steal may occur because of preferential flow from the vertebrobasilar system to the carotid artery via the persistent hypoglossal artery.…”

Persistence of foetal anastomoses between carotid and vertebrobasilar arteries is well recognised, but their bilateral presence is rare. We report a case of bilateral persistent hypoglossal arteries. Absence of bilateral vertebral arteries was incidentally noted on neck ultrasound examination. Subsequent MRI confirmed this and revealed persistent hypoglossal arteries that arose bilaterally from the cervical internal carotid artery, entered the cranium through the hypoglossal canal and joined the lower portion of the basilar artery.

Persistent hypoglossal artery associated with aneurysms

Abstract: Two cases of persistent hypoglossal artery associated with aneurysm are presented. In one case the aneurysm arose from the anterior communicating artery and in the other from the persistent hypoglossal artery itself. Both aneurysms were treated successfully with direct surgery.
