Ependymoma of the cauda equina starting with communicating hydrocephalus: a case report.
The presence of concomitant hydrocephalus in cases with spinal cord tumors is relatively rare. Here, we describe a case of myxopapillary ependymoma of the cauda equina starting with communicating hydrocephalus in a 14-year-old boy. The patient presented to the clinic without underlying causes of hydrocephalus on the neuroimaging data. After ventriculoperitoneal shunt placement, despite the numerous malfunction incidents, the patient was doing well. Eight years later, he developed progressive weakness and coldness of the lower limbs. Multiple cystic lesions in the cervicothoracic area were found on magnetic resonance imaging. Decompressive hemilaminectomy of the cervicothoracic region was performed with temporary improvement of the patient's condition. Because of persisting complaints, the sacral area of the spine was also observed and neuroimaging data for a tumoral lesion in the cauda equina region were found. The lesion was surgically removed and the histological result was myxopapillary ependymoma. Therefore, cases presenting with internal hydrocephalus without clear-cut intracranial etiology should have detailed neuroimaging of the whole central nervous system.
