Female, 10 years old, status post cardiac arrest. The choroid plexus within the right lateral ventricular atrium is enlarged relative to the left. The morphology of this tissue is frond-like without any notable cysts. The tissue demonstrates susceptibility effect which may reflect calcification or blood product.The lateral ventricles are not enlarged. The fourth ventricle is slightly prominent which may reflect mild vermian hypoplasia. No evidence of parenchymal edema is seen. No restricted diffusion is evident to suggest acute ischemia. No acute intracranial hemorrhage or any abnormal extra-axial fluid collection is detected. The mesial temporal structures are unremarkable.
1.No evidence of ischemic injury or any other acute intracranial abnormality.2.Asymmetric enlargement of the choroid plexus within the right lateral ventricular atrium is seen. This could represent a choroid plexus papilloma, less likely normal variant hypertrophy. No evidence of lateral ventricular enlargement is seen to suggest CSF overproduction. Further evaluation with postcontrast imaging should be considered.
