ABSTRACT
We report a rare case of meningioma associated with meningioangiomatosis in a 9-year-old male patient who showed none of the stigmata of neurofibromatosis 2. Brain magnetic resonance images showed marked cortical calcification with slight contrast-enhancement in the parieto-occipital lobe. The resected mass showed that the lesion was mainly composed of meningioangiomatosis and a small focus was transformed into meningioma. To date, only 17 cases of such combined lesions have been reported in English medical literature. We report a rare case of meningioma that arose from meningioangiomatosis.
Key Words: Meningioangiomatosis; Meningioma
