Protean Manifestations and Diagnostic Challenges Including Discordance Between Electrodiagnostic-Radiologic Studies in Neurolymphomatosis.

INTRODUCTION

Malignant lymphocytic infiltration of the central nervous system (CNS) and peripheral nervous system (PNS) is diagnostically challenging and informs treatment and prognosis.

CASE REPORT: We describe the clinical course of a 49-year-old man with CNS and PNS relapse of mantle cell lymphoma and the diagnostic modalities that enabled the diagnosis of neurolymphomatosis.

CONCLUSION

This clinical phenotype reinforces previously reported presentations of neurolymphomatosis and the ability of multimodal diagnostics, when combined with clinical suspicion phenotype, to enable diagnosis of malignant lymphocytic infiltration of the CNS and PNS.
