Less than 50 cases of primary fourth ventricular meningioma are reported in literature. Most of them are hypo- to iso-signal intensity on T1-weighted images and iso- to mildly hyper-signal intensity on T2-weighted images compared with gray matter. Contrast enhancement is strong in all tumors, and the enhancement is homogeneous in 69% and heterogeneous in 31%. It could be harder to differentiate meningiomas of the fourth ventricle from ependymomas and choroid plexus papilloma. Most meningiomas in the fourth ventricle adhere to the choroid plexus. We present a new case and summarize features of magnetic resonance images.
