“…ICA agenesis is a rare congenital anomaly, reported in less than 0.01% of the population. The spectrum of findings ranges from agenesis (complete absence of the ICA and carotid canal) to aplasia (absence of parts of the ICA and of the carotid canal) and hypoplasia (narrowing of the ICA and carotid canal) ( 1 - 4 ) .…”

“…Thirty-six other cases of congenital absence of ICA with intercavernous anastomosis were identiﬁed in the literature. 2,4–34 Age and gender information was not given in one case. 14 We documented sex, laterality of the lesion, age at diagnosis, and presenting clinical signs/symptoms.…”

The absence of an internal carotid artery is a rare congenital anomaly. In the absence of the internal carotid artery, collateral circulations develop through the circle of Willis, persistent embryonic arteries or transcranial collaterals of the external carotid artery. Six pathways of collateral circulation have been described. Intercavernous anastomosis is between cavernous segments of the bilateral internal carotid arteries and is rarely seen. Patients with an absence of the internal carotid artery can be completely asymptomatic. However, these patients can present with subarachnoid hemorrhage or stroke accompanying cerebral aneurysm or abnormal collateral. We combined our case with 33 previous publications to form a retrospective series including 35 cases of unilateral internal carotid artery agenesis with intercavernous anastomosis.

“…Padget 11 noted that the primitive maxillary artery originates from the cavernous ICA lateral to the base of the Rathke pouch in the 3-to 4-mm embryo and has the primary role of supplying the prosencephalon and the optic vesicle. Janicki et al 6 opined that this vessel is most likely incorporated into the inferior hypophyseal artery. Quint et al 12 suggested that insult to the ICA during development might result in compensatory hypertrophy between clival branches of the left and right ICAs, thus forming an intercavernous connection.…”
