A Rare Case of Radiculoplexopathy Induced by Herpes Zoster

Abstract

This case report discusses a rare instance of herpes zoster infection presenting with radiculoplexopathy, exhibiting both preganglionic and postganglionic features. A 62-year-old male patient experienced sudden right upper limb weakness following a recent herpes zoster diagnosis. A nerve conduction study, electromyography, and magnetic resonance imaging revealed a right brachial plexopathy involving the upper trunk and posterior cord, accompanied by lesions in the middle to lower cervical roots. Even after several months, the patient’s recovery remained limited, indicating the significance of this case as a reference for clinical progression in instances of both preganglionic and postganglionic neuropathy. This case emphasizes the role of electrophysiological evaluation in zoster-associated paresis to predict disease progression and improve patient management.
