Intracranial cavernous angiomas are benign vascular malformations and can be divided into intra-axial and extra-axial lesions. Extra-axial cavernous angiomas are relatively rare and usually arise in relation to the dura mater and mimick meningiomas. We report a case of cavernous angioma that occured in the falx cerebri of a 22-yr-old female patient with the special focus on neuroradiologic findings. This is the fourth case of cavernous angioma in the falx cerebri reported in the literature to our knowledge.

Meningioma is a common intracranial tumor in adults. Pediatric cases account for approximately 1.5% of all intracranial meningiomas, and very few cases show malignant histological features. Primary pediatric malignant meningioma in the cerebellopontine angle is extremely uncommon. Herein, we report a 2-year-old girl with malignant meningioma in the cerebellopontine angle. The clinical features, diagnosis, and treatment protocol are discussed.
