The distribution of Imbalanced Chromosome Segments in three groups of sporadic solitary meningiomas. Each dot represents an individual tumor. Y-axis indicates the total number of imbalanced chromosome segments (ICS) in each tumor; X-axis shows three groups of meningioma of different grades. The total number of ICS ranges from 0–12 in benign meningiomas, 0–14 in atypical meningiomas and 2–25 in malignant meningiomas.
