Some aspects of the natural history of cerebral arteriovenous malformation

Department of Radiology, National Hospital for Nervous Diseases, Queens Square, London, W.C.1

The authors review the radiological features of plain radiographic manifestations of cerebral arteriovenous malformations and describe five cases which showed serial changes in films taken over intervals from four to 20 years. The most dramatic change was an increase in size of the meningeal vascular markings on the inner table of the skull. This increase was confirmed by angiography. No size increase of the intracerebral component was convincingly demonstrated angiographically in the cases described, but there is adequate evidence from the literature that these malformations may grow spontaneously and/or after surgical interference. Recent standardisation of radiographic and radiological techniques and measurement of cerebral blood flow will assist in future assessment of these spontaneous growth potential.

In a further case described the initial angiograms were negative, but at re-examination two years later an arteriovenous malformation was demonstrated angiographically.
