Abstract：Objective: To explore the value of imaging diagnosis of supratentorial ventricular masses in children. Methods: Forty-five cases(25 males, aged from 4 months to 13 years with a median age of 2 years) of supratentorial ventricular masses in children confirmed by pathology were analyzed retrospectively. Results: Sixteen cases were choroid plexus papillomas, which appeared as lobulated or granular-countered masses. They were hyperattenuating on CT, iso- to hypointense on T1WI, iso- to hyperintense on T2WI and iso- to hypointense on DWI. Contrast-enhanced imaging showed avid enhancement. Six cases were atypical choroid plexus papillomas with the appearance of small calcifications(n=1), CSF spreading(n=2) and peritumoral edema(n=2). One case was choroid plexus carcinoma, which was solid-cystic with hyperintensity on DWI. Four cases were pilocytic astrocytoma, and 2 cases were pilomyxoid astrocytoma. They were located in the third ventricle, with hypointensity on DWI and intense enhancement. Two cases were ependymomas. Two cases were atypical teratoid/rhabdold tumors. One case was subependymal giant cell tumor. One case was meningioma. Ten cases were neuroepithelial cysts, which showed a thin cyst wall. They showed similar intensity to CSF and no enhancement. Conclusion: The types of the supratentorial ventricular masses in children are varied. CT and MRI can reflect certain characteristics of the masses in this region. With the help of clinical and imaging findings, the diagnosis can be drawn in most cases.
