title: Atypical histopathologic type of cystic meningioma.
abstract: The authors report a 21-year-old male with an atypical cystic meningioma in the right parietal area. On T1-weighted imaging (T1WI), the solid component was hypointense, while on T2-weighted imaging (T2WI), it was hyperintense. On T1WI, the cystic component was hypointense, and on T2WI, it was hyperintense. The authors review the literature about incidence, locations, MRI features, cyst type, and intraoperative managements of atypical cystic meningiomas.
