Abstract:

SUMMARY

Intraventricular meningiomas have often been reported; however, literature reveals very few cases localized within foramen of Monro. Herein we report a 57-year-old woman admitted with obstructive hydrocephalus-related symptoms. Strikingly, the lesion was completely calcified in CT and had no marked solid component on MRI. The lesion was completely removed by surgical resection with a transfrontal intraventricular approach. The resected mass was histopathologically diagnosed as meningioma. The patient's symptoms resolved immediately after the operation.
