Abstract

We report a case of rubeosis iridis resulting from agenesis of the internal carotid artery. Agenesis of the internal carotid artery is a rare congenital anomaly, and most patients do remain asymptomatic, but we should realize that this condition may lead to ocular ischemic changes, the result being rubeosis iridis.

Cerebral hemiatrophy, hypoplasia of internal carotid artery, and intracranial aneurysm. A rare association occurring in an infant.

Rema A Afifi, W. H. Bell, Jennifer C. Jacoby … (1987)

A 4-month-old child with a very rare association of primary (congenital) left cerebral hypoplasia, hypoplasia of the left internal carotid artery, and giant anterior communicating artery aneurysm was seen. The aneurysm was detected and treated before rupture. We briefly reviewed the literature on agenesis (hypoplasia) of the internal carotid artery, intracranial aneurysms in childhood, and primary cerebral hypoplasia. It is proposed that cerebral arteriography, cranial computed tomography, or magnetic resonance imaging be performed in all children with primary cerebral hemihypoplasia to establish an etiologic diagnosis and, more importantly, to detect and treat possible associated intracranial aneurysms before they become symptomatic.

Absence of the carotid canals at skull base CT.

Janet A. Young, R Silbergleit, Koen Quint (1992)

Congenital absence of one or both internal carotid arteries (ICAs) has a high association with circle of Willis aneurysm formation. Since the carotid canals in the skull base form secondary to the presence of the embryonic ICA, absence or hypoplasia of a carotid canal on a computed tomographic (CT) scan through the skull base should suggest a congenital ICA abnormality and prompt a search for associated intracranial vascular abnormalities. Of four patients with carotid canal underdevelopment evident at CT, two had associated circle of Willis aneurysms and a third had an extensive skull base rete mirabile supplying an abnormal tangle of vessels in the basal cisterns. Only two patients (one with an aneurysm, one with the skull base rete mirabile) presented with subarachnoid hemorrhage. One patient presented with monocular decreasing vision due to an enlarging aneurysm, and one patient was essentially asymptomatic. If asymmetry or absence of the carotid canals is evident on CT scans of the head, further evaluation to rule out a potentially life-threatening intracranial vascular abnormality such as those found in these patients should be seriously considered, even in a young or asymptomatic patient.

Agenesis of the left internal carotid artery associated with an aneurysm on the right carotid syphon. Case report.

A Servo (1977)

A case is reported with congenital absence of the left internal carotid artery associated with an aneurysm on the contralateral carotid syphon. Eight similar cases are reviewed in brief. The possibility of hemodynamic abnormality as the cause of the aneurysm is discussed.
