Cerebrovascular stenosis in neurofibromatosis type 1 and utility of magnetic resonance angiography: our experience and literature review.

Purpose Neurofibromatosis type 1 (NF1) is a multisystem autosomal dominant disorder that primarily involves the skin and the nervous system. Development of cerebral arterial stenosis is a potentially deadly complication of NF1, which is frequently underestimated. The aim of our paper is to report the frequency of this cerebrovascular disease in a series of patients affected by NF1, using magnetic resonance angiography (MRA). A review of the literature was also performed, focused on the usefulness of MRA in NF1 patients.
