Neurofibromatosis happens. It is abbreviated as NF.

It comes in two flavours:

  1. NF1 (peripheral).
  2. 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]

  1. Bilateral CNVIII masses on imaging.
  2. Unilateral CNVIII mass + first-degree relative with NF2.
  3. First-degree relative with NF2 and 2/4 of the following:
    1. Meningioma (meningothelial meningioma).[4]
    2. Glioma.
    3. Schwannoma.
    4. Juvenile cataract.
