Male patient aged 36 years old, presented by headache and seizures. A Pre-contrast T1WI: shows large heterogeneous isointense intraventricular soft tissue mass. B CE-T1WI: shows mild to moderate enhancement of the lesion. C Pre-contrast FLAIR shows iso to hyperintense intraventricular mass with numerous cystic areas (bubbly appearance) and flow voids inside. D CE-FLAIR: revealed thicker and more extensive enhancement in comparison with CE-T1WI. E, F Pre and post contrast FLAIR at same level: measurements of the SI, denoting the difference between pre and post contrast and confirms the presence of enhancement (CEI = 137, Lesion to background contrast ratio = 1.07). G, H Pre and post contrast T1WI: measurements of the SI in pre and post contrast images (CEI = 51, Lesion to background contrast ratio = 0.04). Final diagnosis: Central neurocytoma
