Vascular malformations are common lesions accounting for approximately 7% of all benign tumours, the majority of which develop in the head and neck region. Generally, vascular malformations such as lymphangiomas, haemangiomas, and arteriovenous communications in the head and the neck represent only an aesthetic problem. However, when localized in the tongue, these lesions can create clinical problems consisting, in the majority of cases, in spontaneous haemorrhage from the mouth. Although uncommon, progressive asymmetric growth of the tongue (macroglossia) can be also observed. Three consecutive cases of vascular malformations of the tongue have been studied with magnetic resonance imaging (MRI). Neither contrast medium administration nor angio-MR technique was used. In our experience, MR appears to be the ideal technique to define the site, extension and origin of vascular malformations, due to its ability to depict the typical signal flow voids in the lesions and to differentiate slow-flow lesions from high-flow ones.
血管畸形是常见病变，约占所有良性肿瘤的7%，其中大多数发生在头颈部区域。一般来说，头颈部的淋巴管瘤、血管瘤和动静脉交通等血管畸形仅表现为美观问题。然而，当这些病变位于舌部时，在大多数情况下会引发临床问题，即口腔自发性出血。虽然不常见，但也可观察到舌部进行性不对称生长（巨舌症）。我们对连续3例舌部血管畸形患者进行了磁共振成像（MRI）研究。未使用造影剂注射和血管造影磁共振技术。根据我们的经验，由于MRI能够显示病变中典型的血流信号空洞，并区分慢血流病变和快血流病变，因此它似乎是确定血管畸形部位、范围和起源的理想技术。
