Next to acoustic neuromas, meningiomas are the most common benign tumour of the posterior fossa. This paper reviews the personal experience of one of the authors with the management of 26 posterior fossa meningiomas and 212 acoustic neuromas. The aim was to compare the clinical and radiological features of these two types of posterior fossa tumours to determine whether they can be differentiated preoperatively. The study also aimed at analysing the surgical treatment of posterior fossa meningiomas. The results showed that posterior fossa meningiomas can usually be differentiated from acoustic neuromas on the basis of clinical and radiological features. Preoperative differentiation aids surgical management, especially for selection of surgical approach. In most instances, posterior fossa meningiomas can be totally resected with minimal morbidity and mortality.

Résumé:

RÉSUMÉ:

Après le neurinome acoustique, le méningiome est la tumeur bénigne la plus fréquente de la fosse postérieure. Cet article rapporte l'expérience personnelle de l'un des auteurs dans le traitement de 26 méningiomes de la fosse postérieure et de 212 neurinomes acoustiques. Le but de ce travail était de comparer les manifestations cliniques et radiologiques de ces deux types de tumeurs de la fosse postérieure afin de déterminer si l'on peut les différencier avant la chirurgie. Nous voulions également analyser le traitement chirurgical des méningiomes de la fosse postérieure. Les résultats ont montré que les méningiomes de la fosse postérieure peuvent habituellement être différenciés par leurs manifestations cliniques et radiologiques. Un diagnostic pré-opératoire précis aide à déterminer la conduite chirurgicale, surtout en ce qui a traite à l'approche chirurgicale. Dans la plupart des cas, les méningiomes de la fosse postérieure peuvent être réséqués complètement avec un taux de morbidité et de mortalité minime.
