Abstract

Objective: To describe and analyze imaging characteristics of meningeal metastases from neuroblastoma in pediatric patients. Methods: Nineteen cases with meningeal metastases from neuroblastoma were selected, 9 males and 10 females, underwent MRI scan examination, 9 of them underwent enhanced MRI scan, 4 of them underwent CT scan examination. Results: Meningeal metastases from neuroblastoma in children often involved the dura. MRI showed the nodular lesions or banded thickening meninges under the skull plate. T1WI showed slightly low or equal signal. T2WI showed equal or slightly high signal. Enhanced MRI scan showed obvious enhancement. CT scan showed crescent-shaped or shuttle-shaped slightly high density under the skull plate. Conclusion: The imaging findings of meningeal metastases from neuroblastoma in children have certain characteristics. Enhanced MRI examination can provide important imaging evidences for clinical diagnosis, treatment and prognosis assessment.
