Abstract

Abstract BACKGROUND AND IMPORTANCE: We report the case of a patient with multiple neuroepithelial tumors of different histological cell types. In this patient, synchronous appearance of tumors of the central nervous system, ie, cervical ependymoma and a fourth ventricle choroid plexus papilloma, was noted. CLINICAL PRESENTATION: A 36-year-old man presented with sensory disturbance of the bilateral upper extremities. Magnetic resonance imaging revealed a heterogeneously enhanced mass with syringomyelia in the upper cervical cord and a well-enhanced mass in the fourth ventricle. The patient underwent bilateral suboccipital craniotomy and laminectomy from the level of C1 to C3 for both lesions. The lesions were grossly resected. Histological and immunohistochemical examinations revealed that the cervical tumor was an ependymoma, and the fourth ventricle tumor was a choroid plexus papilloma. CONCLUSION: The appearance of synchronous multiple neuroepithelial tumors of different histological cell types is extremely rare, and this is the first known case of ependymoma occurring synchronously with choroid plexus papilloma, both tumors having different histological cell types. Displacement and maldifferentiation of primitive, multipotent neuroepithelial cells may be a causative factor for this unique presentation.
