Venous aneurysms are rare and usually develop following trauma. This report describes an aneurysm of the internal jugular vein that was associated with dysplasia of the cervical arteries, in a patient with neurofibromatosis type 1 (NF1). The finding of neurofibromatous tissue in the wall of the aneurysm as well as in small veins, suggested that the venous aneurysm was caused by the neurofibromatous invasion.
- Brain hemorrhage
- Progressive mental deterioration
- Occipital calcification
- Dysplastic external carotid arteries
Surgical treatment or percutaneous transluminal balloon angioplasty is indicated only for those patients with symptomatic carotid arterial disease. FMD, when it produces minimally stenotic lesions — even those affecting a long segment of vessel — may be managed conservatively with antiplatelet therapy, anticoagulant therapy, or both.
