The association of cortical organization disorders with facial hemangiomas or vascular malformations has been described in only a few reports. The purpose of this study was to show the close association of these cutaneous anomalies with cortical dysplasias and intracranial vascular abnormalities.
Five patients, all women, with cutaneous vascular abnormalities, 4 with hemangioma and 1 with vascular malformation, were studied with MR and MR angiography.
All 5 of the patients showed cortical dysplasia. The cutaneous lesions involved the left frontal region, ipsilateral to the cerebral hemisphere with cortical dysplasia, in all of the patients. Four patients had seizures that responded well to antiepileptic drugs. Hemispheric hypoplasia was associated with the cortical dysplasia in all 5 of the patients. Arterial abnormalities were found in all of the patients, consisting of aplasia of the ipsilateral internal carotid artery in 2, persistence of the trigeminal artery in 2, persistence of both proatlantal arteries and double kinking in the internal carotid artery in 1, and origin of both anterior cerebral arteries from the same internal carotid in all 5 of the patients, 1 of whom also showed an intracavernous anterior cerebral artery origin of the same side of the hemispheric hypoplasia and polymicrogyria. Seizures and mild psychomotor delay could be caused by the cortical dysplasia and the hemispheric hypoplasia.
The presence of many congenital vascular abnormalities in this series suggests that facial hemangioma and vascular malformations may be in close relationship with cortical and vascular abnormalities. The reason that the vascular and cortical abnormalities occurred in the left side in all 5 of the patients and the mechanism underlying the association of both malformations are unclear. A genetic origin is suggested.
仅有少数报告描述了皮质组织紊乱与面部血管瘤或血管畸形之间的关联。本研究的目的是表明这些皮肤异常与皮质发育异常和颅内血管异常密切相关。
对5例患有皮肤血管异常的女性患者进行了研究,其中4例为血管瘤,1例为血管畸形,均接受了磁共振成像(MR)和磁共振血管造影(MRA)检查。
所有5例患者均表现出皮质发育异常。所有患者的皮肤病变均累及与存在皮质发育异常的大脑半球同侧的左额叶区域。4例患者有癫痫发作,对抗癫痫药物反应良好。所有5例患者的皮质发育异常均伴有半球发育不全。所有患者均发现动脉异常,其中2例同侧颈内动脉发育不全,2例三叉动脉持续存在,1例前寰椎动脉均持续存在且颈内动脉双折曲,所有5例患者双侧大脑前动脉均起自同一颈内动脉,其中1例还表现为半球发育不全和多小脑回同侧的海绵窦内大脑前动脉起源。癫痫发作和轻度精神运动发育迟缓可能由皮质发育异常和半球发育不全引起。
本系列中存在多种先天性血管异常表明,面部血管瘤和血管畸形可能与皮质和血管异常密切相关。所有5例患者的血管和皮质异常均发生在左侧,以及两种畸形关联的潜在机制尚不清楚。提示可能存在遗传起源。
