Sudden-onset back pain and cauda equina syndrome in an adolescent: a case report.

Recent epidemiological studies have shown that childhood back pain is a common complaint often prompting medical attention and that it is infrequently the result of serious etiology. This challenges the traditional view that childhood back pain was an uncommon and ominous symptom, always indicative of significant pathology. We report the case of an adolescent boy who presented to the pediatric emergency department with what initially seemed to be benign back pain. This case illustrates an extremely rare ED presentation of myxopapillary ependymoma, which rapidly evolved into cauda equina syndrome requiring urgent neurosurgical intervention. A review of pediatric back pain and cauda equina syndrome is presented.
