摘要Summary: Vascular malformations arising from the wall of the external jugular vein are rare. This case series discusses the sonographic and MR imaging appearances of four such cases and reviews the literature. The diagnosis should be suggested preoperatively particularly because of the close relationship such malformations to the external jugular vein, as this helps surgeons to plan the operative procedure. The imaging appearances are similar to those of other vascular malformations elsewhere in the head and neck.

Mulliken and Glowacki, in 1982, proposed a classification of vascular lesions based on endothelial characteristics (1) that gained wide acceptance. In this scheme, vascular lesions were separated into two major groups: infantile hemangiomas and vascular malformations. Hemangiomas are characterized by endothelial cellular hyperplasia and proliferation, characteristically grow rapidly for 6–8 months after birth, and then regress to a variable extent. On the other hand, vascular malformations have a normal endothelial cell cycle and do not involute.

Intrinsic vascular lesions arising from the wall of the external jugular vein are very rare. This case series discusses the sonographic and MR imaging appearances of four cases of vascular malformations of external jugular venous wall, highlighting the imaging appearances that help to make the preoperative diagnosis. The differential diagnosis and clinical appearances are discussed and the literature reviewed.
