Neurolymphomatosis of brachial plexus: A rare clinical presentation and the role of 18F-FDG PET/CT

Neurolymphomatosis (NLY) is a type of rare disease with poor prognosis, characterized by infiltration of nerves, nerve roots and plexus. We report a case of 54-years old female patient non-diabetic and normotensive diagnosed with chronic lymphocytic leukemia presented with pain in the neck and arm and numbness in the ipsilateral hand. The patient underwent 18F fluorodeoxyglucose PET/CT scan, which showed increased tracer accumulation in the right neck and supraclavicular region in the brachial plexus. 18F-FDG PETCT is highly sensitive technique for early localization of NLY than MRI or CT alone.
