Abstract

Purpose: This is a description of the main middle cerebral artery (MCA) anomalies from the neuroradiological and embryological point of view, discussing the practical implications and the association with other vascular diseases.

Methods: Among the patients who underwent digital subtraction angiography (DSA) at our institution in a short time period (from 1 January 2021 to 31 December 2023), we selected three cases with high-quality images, representative for the main MCA anomalies, i.e., accessory, duplicated, and twig-like MCA.

Results: We describe a series of three cases, illustrating the three main embryological anomalies of MCA, including accessory MCA, duplicated MCA, and twig-like MCA. All patients underwent neuroradiological investigations at our institution because of the acute occurrence of neurological symptoms and the findings are presented using computed tomography angiography (CTA), magnetic resonance angiography (MRA), and DSA with a detailed description. These three variants have a very low prevalence and they were reported and described more systematically in the Asian population than in the European population. Both noninvasive and invasive neuroimaging techniques were used for investigating these patients, and catheter angiography still provides the more informative content for precisely imaging the angioarchitecture of these variants and the association with aneurysms on other cerebral arteries. The knowledge of the embryology of these variants is of paramount importance in order to make easier their identification and reporting and to enhance their understanding.

Conclusions: MCA anomalies should be known and carefully checked in order to avoid misdiagnosis with disease and may affect the treatment of acute stroke.

大脑中动脉异常的神经影像学:附3例报告。
目的:从神经放射学和胚胎学的角度描述大脑中动脉(MCA)主要异常,讨论其实际意义及其与其他血管疾病的联系。方法:在我院短期内(2021年1月1日至2023年12月31日)行数字减影血管造影(DSA)的患者中,我们选择了3例高质量的图像,代表了主要的MCA异常,即附属MCA、重复MCA和树枝状MCA。结果:我们描述了一系列的三个病例,说明了三种主要的胚胎学异常,包括副MCA、重复MCA和小枝样MCA。由于急性出现神经系统症状,所有患者均在我院接受了神经影像学检查,并通过计算机断层血管造影(CTA)、磁共振血管造影(MRA)和DSA进行了详细描述。这三种变异的流行率很低,在亚洲人群中比在欧洲人群中有更系统的报道和描述。无创和有创神经成像技术均用于调查这些患者,导管血管造影仍然为精确成像这些变异的血管结构以及与其他脑动脉动脉瘤的关系提供了更多信息内容。这些变异的胚胎学知识是至关重要的,以便更容易地识别和报告,并加强对它们的理解。结论:急性脑卒中时,应及早认识并仔细检查MCA异常,以免误诊,影响治疗。

期刊介绍: The journal has been expanded to encompass all aspects of pediatric neurosciences concerning the developmental and acquired abnormalities of the nervous system and its coverings, functional disorders, epilepsy, spasticity, basic and clinical neuro-oncology, rehabilitation and trauma. Global pediatric neurosurgery is an additional field of interest that will be considered for publication in the journal.
