Аннотация
BACKGROUND AND IMPORTANCE: We report the first case of synchronous choroid plexus papilloma of the fourth ventricle and myxopapillary ependymoma of the filum terminale. Both are papillary World Health Organization grade I tumors known to disseminate via cerebrospinal fluid pathways.
CLINICAL PRESENTATION: A 65-year-old man presented with an incidental mass in the fourth ventricle found on a computed tomography scan of the head after a motor vehicle collision and an intradural mass of the filum terminale. The patient underwent resection of the fourth ventricle mass. After pathological diagnosis of a choroid plexus papilloma, the patient underwent resection of the spinal cord tumor.
CONCLUSION: This case underscores the need for separate pathological diagnosis in a patient with an intradural spine lesion in the context of a benign intracranial lesion. We detail a panel of immunohistochemical markers essential for distinguishing the 2 papillary neuroectodermal tumors recovered in this case.
