Abstract:
Neurolymphomatosis (NL) is lymphomatous infiltration of peripheral nerves, and is an uncommon manifestation of non-Hodgkin's lymphoma (NHL). Although nerve biopsy is the main method for histological diagnosis, a blind nerve biopsy may not be diagnostic. While CT and MRI have been used to detect NL, recent reports demonstrated the benefit of integrated positron emission tomography (PET) using F18-2-fluoro-2-deoxy-D-glucose (FDG) combined with computed tomography (CT). We described the utility of FDG PET-CT in this uncommon subgroup of NHL where it can assist in establishing the diagnosis, the potential to guide sites for biopsy and in the assessment of response to therapy.
