Two cases of clear cell ependymoma (CCE) of the fourth ventricle are reported in a 49‐year‐old woman with dysphagia and a 59‐year‐old woman with dizziness and gait disturbance. CCE is a relatively new variant of ependymoma added to the WHO classification of tumors in 1993. Tumor cells display an oligodendroglioma‐like appearance with a clear perinuclear halo. Most infratentorial CCE tumors are located in the cerebellum. There are only three cases, including the present two cases, that have been reported to affect the fourth ventricle.
