Anterior jugular venous aneurysm

An anterior jugular venous aneurysm in a 4-year-old boy is described. Noninvasive radiology confirmed the diagnosis and excluded any deeper cervical venous malformation. Surgical excision was uncomplicated. Whilst the internal jugular vein is the commonest site of a venous aneurysm, recognition that the anterior jugular vein can be affected in isolation may help to avoid diagnostic confusion. A unifying concept of pathogenesis is suggested.
