18F fluorodeoxyglucose positron-emission tomography–computed tomography in the diagnosis of brachial plexopathy in carcinoma breast

Abstract

We report the case of a 42-year-old female who had received treatment for carcinoma left breast, now presenting with pain in the left upper limb for 2 months and paraesthesia for 1 month. Magnetic resonance imaging of the brachial plexus revealed altered signal intensity involving divisions and cords of the brachial plexus on the left side. 18F fluorodeoxyglucose (FDG) positron emission tomography-computed tomography revealed moderately increased FDG concentration in multiple ill-defined nodules, along the left brachial plexus suggestive of metastatic brachial plexopathy.
