Demonstration of peripheral nerve root involvement by non-Hodgkin's lymphoma on 18F-FDG PET/CT.

摘要

We present images obtained during whole-body 18F-flu-orodeoxyglucose (FDG) positron emission tomography (PET)/CT requested for evaluation of extent of disease in a 66-year-old man diagnosed with non-Hodgkin's lymphoma (NHL). The patient presented 20 months prior to the scan with bilateral lower extremity paresthesia and weakness, eventually progressing to paraplegia, and initially treated for inflammatory neuropathy. After an extended workup, including multiple lumbar punctures, flow cytometry from cells found in the central nervous system (CNS) fluid revealed CD10+ B-cell NHL. Lymphoma has been described as the Great Mimicker [1, 2] in clinical practice and in imaging for its protean manifestations and inclusion in many differential diagnoses.
