Acquired Jugular Vein Aneurysm

Abstract EN

Venous malformations of the jugular veins are rare findings.

Aneurysms and phlebectasias are the lesions most often reported.

We report on an adult patient with an abruptly appearing large tumorous mass on the left side of the neck identified as a jugular vein aneurysm.

Upon clinical examination with ultrasound, a lateral neck cyst was primarily suspected.

Surgery revealed a saccular aneurysm in intimate connection with the internal jugular vein.

Histology showed an organized hematoma inside the aneurysmal sac, which had a focally thinned muscular layer.

The terminology and the treatment guidelines of venous dilatation lesions are discussed.

For phlebectasias, conservative treatment is usually recommended, whereas for saccular aneurysms, surgical resection is the treatment of choice.

While an exact classification based on etiology and pathophysiology is not possible, a more uniform taxonomy would clarify the guidelines for different therapeutic modalities for venous dilatation lesions.
