Four cases of distinctive meningiomas with Zellballen growth pattern
Meningiomas are attributed to those tumours with slow-growing pattern occurring predominantly in middle-aged or elderly patients. Fifteen histological variants have been described based on the variable histomorphological features. Herein we report four cases with specific Zellballen growth pattern, giving the tumours a ‘paraganglioma-like’ general aspect. The diagnosis of meningiomas was confirmed by immunohistochemical and ultrastructural findings. Histopathologists should be aware of this specific morphology which can lead to misdiagnosis.
