Neurofibromatosis is a genetic conditions, also known as von Recklinghausen's disease. It is abbreviated as NF.
It comes in two flavours:
- NF1 (peripheral).
- NF2 (central).
NF1
Features (need 2/7 to diagnose):[1]
- Two or more neurofibromas or one plexiform neurofibroma.
- Café-au-lait spots.
- Freckles in axilla or inguinal area.
- Optic nerve glioma.
- Iris hamartomas (Lisch nodules).
- Sphenoid dysplasia or typical long-bone abnormalities (e.g. bowing).
- First-degree relative with NF1.
Mnemonic
CAFE SPOT:[2]
- Café-au-lait spots.
- Axillary or inguinal freckling.
- neuroFibroma (two or more) or plexiform neurofibroma (one).
- Eye hamartomas (Lisch nodules).
- Skeletal abnormalities, e.g. sphenoid dysplasia, leg bowing.
- Positive family history.
- Optic Tumour (optic nerve glioma).
NF2
Features (need 1/3 to diagnose):[3]
- Bilateral CNVIII masses on imaging.
- Unilateral CNVIII mass + first-degree relative with NF2.
- First-degree relative with NF2 and 2/4 of the following:
- Meningioma (meningothelial meningioma).[4]
- Glioma.
- Schwannoma.
- Juvenile cataract.
