Abstract

A 29-year-old woman had 1-month history of back pain radiating into lower extremities, motor weakness, and sensory abnormalities in both lower extremities. Contrast-enhanced spinal magnetic resonance imaging (MRI) revealed a homogeneously enhancing mass at the T12∼L1 and several intradural enhancing nodular lesions at L2∼S1. Tumor resection surgery was performed and following histological examination showed that the tumor satisfied the diagnostic criteria for atypical choroid plexus papilloma (CPP). To find primary tumor sites, contrast-enhanced brain MRI, whole spine MRI, and PET-CT were carried out and additional lesions were detected at the fourth ventricle, right cerebellum, and upper thoracic spinal cord. This is a very rare case of metastatic atypical CPP that involves brain, upper thoracic spinal cord, and cauda equina with initial manifestation of radicular symptoms without clinical signs of primary brain lesion.
