Research output: Contribution to journalArticlepeer-review


This reports a clinical and radiological review of 34 patients with benign intracranial hypertension investigated in the neurological departments of the Newcastle upon Tyne University Hospitals between 1960 and 1972. A review of the neuroradiological investigations showed that 9% had signs of raised intracranial pressure on the plain skull radiographs; pneumoencephalography was performed in 10 patients without any deleterious effects in spite of the papilloedema; and small ventricles with sharp superior lateral angles were not the diagnostic feature of this syndrome. Only 44% had this appearance, and on measurement 76% had ventricular volumes which were estimated by the method of Bull (1961) to be above the upper limit of normal. The average length of follow up was 6 yr. The long term prognosis for this syndrome was excellent, but 8% had visual impairment; in these cases, the prefix 'benign' was not applicable. No alternate name for this syndrome is entirely satisfactory, and there are advantages for retaining the term benign intracranial hypertension for this syndrome, which is probably due to cerebral oedema, and in some cases may be found to have an underlying precipitating cause.
