Isolated aneurysm of the internal jugular vein: a report of three cases

Isolated venous aneurysms are rare in children. Three patients presented with progressively enlarging cervical masses that proved to be fusiform aneurysms of the internal jugular vein. Surgical excision was carried out in each instance. Histopathologic examination revealed changes suggesting elastic tissue dysplasia similar to that previously described in abnormal carotid arteries of some children.
