“…An oscillating intraluminal mass echo in the CCA or ICA has been reported in patients with cardioembolic stroke 51) . A diffuse circumferential mild hypoechoic thickening of the intima-media complex resulting from granulomatous inflammatory changes, termed the "macaroni sign," has been detected in patients with Takayasu disease 52) . This "macaroni sign" has been widely used not only for the diagnosis for Takayasu disease but also for the evaluation of inflammatory activity.…”

“…A severe, diffuse wall thickening is observed especially in the internal and common carotid arteries. The wall deposit is typically homogeneous, midechoic, circumferential and has been described as the ''macaroni sign'' by Maeda et al [9].…”

“…US sign of giant cell arteritis is a dark halo around the artery lumen which may be due to edema of the artery wall. In clinical practice it is important to keep also this in mind, as the hypoechoic circumferential halo typical of large-vessel giant cell arteritis like the midechoic homogeneous wall thickening of the Takayasu arteritis, may disappear with corticosteroid therapy [9,10].…”

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.

“…En la ecografía se encontró engrosamiento mural concéntrico de la carótida común, este engrosamiento difuso de la arteria es compatible con arteritis (1). Las características ecográficas de engrosamiento difuso de la arteria hace pensar en arteritis debido a una vasculitis de grandes vasos, al ser estas vasculitis sistémicas existe la posibilidad del compromiso otras arterias mayores como la aorta, la subclavia o la carótida común contralateral; por lo que ante esta sospecha se debe evaluar con imágenes (ecografía, tomografía o resonancia) los otros grandes vasos, ya que el examen físico tiene poca sensibilidad para descartar el compromiso de otras arterias (2).…”
