Neurolymphomatosis: A Surreal Presentation of Lymphoma

Abstract

Background: Neurolymphomatosis is a neurologic complication poorly recognized by neurologists and oncologists and presents usually several months after successful treatment of systemic lymphoma. Other disorders that must be differentiated from these entities include peripheral-nerve or nerve root compression and paraneoplastic neuropathy. Aim: To describe the unusual occurrence of neurolymphomatosis in a patient of B-cell lymphoma. Method: Diagnosis was made by demonstration of enhancement of nerve roots on Magnetic Resonance Imaging of the brachial, lumbosacral plexus, peripheral nerves or by increased hyper-metabolic activity along the course of affected nerves on fluorodeoxyglucose positron emission tomography (FDG-PET). Results and Conclusion: MRI and PET-CT are imaging modalities of choice for evaluation of patients with lymphoma and suspected neural involvement. Treatment of neurolymphomatosis consists of focal radiotherapy and high-dose methotrexate therapy.
