The primitive hypoglossal artery (PHA) is a rare persistent carotid-basilar anastomosis. Usually it is found incidentally on angiography, but detection may be of importance for patient management. In the presented case MR- and CT angiography, which to our knowledge have not yet been reported in PHA, provided important additional information.
原始舌下动脉（PHA）是一种罕见的持续存在的颈动脉-基底动脉吻合。通常它在血管造影时偶然发现，但检测对于患者管理可能很重要。在本病例中，据我们所知，PHA尚未有磁共振血管造影（MR-血管造影）和计算机断层血管造影（CT血管造影）的报道，而这两种检查提供了重要的额外信息。
