title: Case report: magnetic resonance imaging of primary lymphoma of the cauda equina.
abstract: Malignant lymphoma of the central nervous system is usually confined within the cranium, with primary involvement of the spinal cord and nerve roots being very rare. The occurrence of primary lymphoma in the cauda equina in a 16-year-old Chinese male is reported. Contrast enhancement during magnetic resonance imaging is useful in accurately demonstrating disease extent prior to surgery.
