BACKGROUND: As the clinical and pathological significance of @entity424 (CCE) has not been recognized in the past, eight cases of cerebellar CCEs were studied. METHODS: Subjects were six @entity1 and two @entity1 , and their ages ranged from 23 to 64 years old. Their neuroradiological, operative, and pathological features were reviewed. RESULTS: The @entity5 frequently showed high vascularity on angiography and marked enhancement on computerized tomography. Grossly, six @entity5 exhibited a "cyst with mural nodule" and two were mostly solid containing small cysts. At operation, the @entity5 nodules were dark red in color and the cysts contained xanthochromic fluid. Microscopically, all @entity5 displayed mostly clear round cells and abundant blood vessels. Although they commonly lacked the characteristic features of @entity424 , immunostaining and electron microscopy confirmed their ependymal origin. CONCLUSIONS: The results indicate that cerebellar CCEs closely mimic @entity279 both clinically and pathologically, which suggests CCE should be considered in the differential diagnosis of @entity5 of the cerebellum. Some diagnostic clues to differentiate CCE from @entity279 are discussed.
