Meningiomas, in particular the Atypical (grade 2), vary greatly in their behaviour and prognosis. Over a 19 year period, we operated on 169 meningiomas (on 86 patients) and of those, 9 cases of atypical meningiomas were found which met the 2007 World Health Organization (WHO) classification. The 9 patients represented 5.3% of all meningiomas. The average presenting age was 51 years and average follow-up was 103 months with 5 patients passing away between 38 and 219 months after diagnosis. The time to first recurrence was 24 months with 1 patient suffering 12 recurrences and 2 cases having metastases. Although we had a small number of atypical meningiomas, we believe our paper highlights the unpredictable and difficult nature of these tumours.
