Introduction: Neurolymphomatosis (NL) is a rare disorder characterized by invasion of cranial or peripheral nerves, nerve roots, or plexi, usually by aggressive subtypes of non-Hodgkin lymphoma (NHL). The most common clinical presentation is that of a painful polyneuropathy or polyradiculopathy, followed by cranial neuropathy and, less frequently, by painless polyneuropathy. Methods: Clinical and pathologic findings are reported for 2 NL cases. Results: The following 2 patients with NL, with disparate clinical presentations, are presented: a patient with subacute onset, painful, multifocal, mixed axonal and demyelinating radiculoplexus neuropathy due to a large B-cell NHL, who required 2 targeted fascicular nerve biopsies to demonstrate NL; and a patient with a slowly progressive, length-dependent axonal polyneuropathy due to a low-grade B-cell lymphoproliferative disorder, as shown on a diagnostic sural nerve biopsy. Conclusions: The cases described illustrate the wide clinical spectrum of NL.
