Neurofibromatosis is a genetic conditions, also known as von Recklinghausen's disease. It is abbreviated as NF.
It comes in two flavours:
- Neurofibromatosis type 1 - NF1 (peripheral).
- Neurofibromatosis type 2 - NF2 (central).
Neurofibromatosis type 1
Features (need 2/7 to diagnose):[1]
- Two or more neurofibromas or one plexiform neurofibroma.
- May give rise to a malignant peripheral nerve sheath tumour.
- 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).
Possible association
Neurofibromatosis type 2
Features (need 1/3 to diagnose):[4]
- 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).[5]
- Glioma.
- Schwannoma.
- Juvenile cataract.
