S. Borofsky, L.M. Neurofibromatosis type 2 (NF2) is a rare autosomal dominant neurocutaneous disorder (phakomatosis) manifesting as a development of multiple CNS tumors.Unlike neurofibromatosis type 1 (NF1), it is not associated with neurofibromas.

Neurofibromatosis type 1 (NF1) is the most common of the phakomatoses and has a variety of localized or, more frequently, systemic manifestations throughout the thorax, abdomen, pelvis, and extremities. 8. Part 1: NF1. … NF is classically divided into two types: NF type 1 (NF-1), also known as von Recklinghausen disease or peripheral neurofibromatosis, and NF type 2 (NF-2) or central neurofibromatosis.

NF1 ranges from mild to severe, and can cause more symptoms in some people than in others. From the archives of the AFIP: pilocytic astrocytoma: radiologic-pathologic correlation. As is the case with many phakomatoses, NF1 results in a variety of abnormalities of variable severity. To make the clinical diagnosis two or more of the following are required 2: 1. 7.
