KEYWORDSArteries, abnormalities; Hypoplasia internal carotid artery; Extracranial duplex sonography; Transcranial duplex sonography.Abstract Introduction: Hypoplasia of the internal carotid artery (HICA) is a rare congenital anomaly caused by an incomplete development of the organ, and only a few cases are reported in the literature. The prevalence of HICA (including agenesia and aplasia) is estimated to about 0.01%. Case report: We describe a case of a 66-year-old man with hearing loss on the left side and no other symptoms or signs related to vascular impairment. HICA was discovered incidentally by color duplex sonography of the extracranial cerebral vessel and confirmed by magnetic resonance imaging angiography (angio MRI) and computed tomography (CT) of the head. Discussion: Compensatory flow allows HICA patients to remain asymptomatic, but complications may occur. The pathways of the collateral circulation in association with aplasia or HICA are described. A differential diagnosis was made on the basis of ultrasonographic (US) detection of diffuse luminal narrowing of the internal carotid artery (ICA). Recognition of this disease has important clinical implications.Sommario Introduzione: L'ipoplasia della carotide interna è una rara anomalia congenita che si verifica per un incompleto sviluppo dell'organo. Soltanto pochi casi sono stati riportati in letteratura. La prevalenza dell'ipoplasia se calcolata insieme alla agenesia e alla aplasia è stimata essere dello 0.01%. Caso clinico: Descriviamo il caso di un uomo di 66 anni affetto da ipoacusia all'orecchio sinistro e nessun segno di problemi vascolari. L'ipoplasia della carotide interna fu scoperta accidentalmente durante un ecocolordoppler dei tronchi sovraortici e venne confermata da angio risonanza magnetica e tomografia assiale computerizzata del cranio. Discussione: I flussi di compenso permettono a questi pazienti di rimanere asintomatici per molti anni ma possono essere causa nel tempo di complicazioni. Vengono descritti i pattern di circolazione collaterale associati alla ipoplasia della carotide interna. Vengono messi in evidenza i segni ultrasonografici che permettono la diagnosi differenziale in caso di diffuso * Corresponding author.

“…This is a rare congenital abnormality, with an incidence rate of 0.01% (2,3,4). A recent study analyzed magnetic resonance imaging (MRI) and cerebral digital subtraction angiography (DSA) series and reported higher rates of ICA agenesis or hypoplasia at 0.13% (5).…”

135Congenital internal carotid artery (ICA) agenesis is a rare abnormality. People with this abnormality usually have adequate collateral circulation and remain asymptomatic for many years. However, patients may also present with pulsatile tinnitus, headache or blurred vision, or rarely with ischemic stroke or subarachnoid hemorrhage. Diagnosis is usually incidental with the performance of carotid artery Doppler ultrasonography or cervical/cranial magnetic resonance imaging owing to other symptoms. ICA agenesis might also be misdiagnosed as ICA occlusion. In this manuscript, we report a patient with ICA agenesis who initially presented with facial paresthesis and was referred to our center for interventional therapy for left-sided ICA occlusion. Keywords: Internal carotid artery, agenesis, occlusionKonjenital internal karotis arteri (ICA, internal carotid artery) agenezisi nadir görülen bir anomalidir. Bu anomaliye sahip hastaların çoğu, yeterli kollateral dolaşım sayesinde uzun zaman asemptomatik olarak kalır. Az sıklıkta hastalar pulsatil tinnitus, baş ağrısı veya bulanık görme gibi yakınmalar ve nadiren iskemik inme ya da subaraknoid kanama tablosu ile başvurabilirler. Tanı genellikle başka bir nedenle yapılmış olan karotis arteri renkli Doppler ultrasonografisi veya servikal/ kranyal manyetik rezonans görüntülemeleri sırasında tesadüfen konur. Ancak dikkatli olunmadığı takdirde ICA tıkanması olarak yanlış bir tanı konulabilir. Bu yazıda, yüzünde yanma şikayeti ile başvuran ve sol ICA tıkanıklığı tanısı ile girişimsel tedavi amacıyla merkezimize yönlendirilen ancak ICA agenezi tanısı konulan bir hasta sunulmaktadır.
