Eight cases of intracranial extensions of juvenile nasopharyngeal angiofibromas (JNA) are presented. These form 33% of the cases of JNA treated during a 5-year period (1988-93). A high incidence of visual complications in this stage of tumour is observed and the basis of this is discussed. Death results from serious complications of severe haemorrhage and cerebro-spinal fluid leak. The intradural intracranial extensions of the tumour warrant careful approach in terms of surgery, because of their greater risk for complications during the dissection.
