Objective To investigate the imaging appearances and pathological features of Central Neurocytoma (CNC) in order to improve diagnostic accuracy. Methods 11 cases with CNC which were confirmed by surgery and pathology were retrospectively analyzed with imaging and pathological findings. Results 11 patients received MRI examination and of which 4 cases also underwent CT scans. 10 lesions located in lateral ventricle, near the foramen of Monro, and were attached to the septum pellucidum with a broad base. On CT and MRI tumors showed cystic-solidary, which was called"sponge sign" or "soap bubble sign". 3 cases presented calcification on CT. Multiple solid spicules between the edge of the lesions and the lateral ventricle wall were observed in 8 lesions. Postcontrast MRI revealed mild to moderate enhancement in 8 cases, 3 cases showed inhomogeneous obviously enhancement.7 cases were found enhanced vessels in the internal or peripheral of the lesions. 10 cases were accompanied with different degrees of hydrocephalus. Only 1 case in the left frontal and temporal lobes. Conclusion Central Neurocytomas had certain characteristics in clinical, imaging and pathological manifestations. Combined with the onset age and typical location may helpful to the diagnosis and differentiation from other tumors residing in lateral ventricle.
