Pseudoaneurysma of the external jugular vein communicating with the internal jugular vein. Case report

True and false aneurysmas (pseudoaneurysmas) of veins are very rare conditions. We present the case of a 58 year old woman with a progressive spheric enlargement with pusatile character of the right laterocervical area. Ultrasonography established the diagnosis showing the vascular mass with turbulent flow belonging to the external jugular vein and the communication with the internal jugular vein.. The particularities of this case are the absence of an obvious etiology and the particular variant of flow direction from internal towards the external jugular vein. To the best of our knowledge, this is the first case of pseudoaneurysma of the external jugular vein reported in literature.
