Central nervous system (CNS) lymphoma is of two types: primary and secondary (more
common). Primary CNS lymphoma usually presents as parenchymal lesions having characteristic
imaging findings and may be associated with leptomeningeal involvement. Involvement
of multiple cranial nerves as the initial manifestation of primary CNS lymphoma with
the development of typical parenchymal lesions on follow-up is a rare entity. This
nerve involvement is termed as neurolymphomatosis. We present the magnetic resonance
imaging features of five patients presenting with neurolymphomatosis due to non-Hodgkin's
lymphoma.
