Spontaneous cerebrospinal fluid (CSF) rhinorrhoea in spongiform dysplasia of the cranium: an unusual presentation of neurofibromatosis

Abstract

A 20-year-old woman with neurofibromatosis presented with CSF rhinorrhoea. Spongiform dysplasia of the cranium was found. The dysplastic bone contained CSF. The exact site of the CSF fistula into the calvarium and into the paranasal sinuses could not be detected on investigation but nasal packing of the ethmoid and sphenoid sinuses controlled the rhinorrhoea. The unique features of this case are presented along with a brief review of the literature.
