Neurolymphomatosis of Brachial Plexus in Patients with Non-Hodgkin's Lymphoma
(a) PET-CT. Strong linear FDG uptake along the right brachial plexus was found, which had not been seen on PET-CT performed 2 months ago (white arrow). (b) Cervical spine MRI with contrast enhancement. The trunk of the right brachial plexus on the level of C5 and C6 were thickened with heterogeneous enhancement, suggesting lymphoma infiltration. (c) Follow-up PET-CT. Right brachial plexus invasion was improved after chemoradiotherapy, but new lesions were seen in right temporal base, right sciatic nerve, and right adrenal gland.
