Résumé
Two patients with giant dumbbell foramen magnum neurinomas are reported. The intradural component was located anterior to the cervicomedullary junction while the extradural and extraspinal portion of the tumor had grown large enough to present as a neck swelling. In both patients total surgical removal was achieved by a single-stage posterior midline approach. Both patients had complete neurological recovery.

We report a patient with an uncommon presentation in the form of massive bilateral calvarial hyperostosis with bi-parasagittal en plaque meningioma. The tumour was removed by bilateral fronto-parieto-occipital craniotomies. The patient was subjected to post operative radiotherapy to reduce the chances of recurrance. The management of such a case is a surgical challenge.
