Effective Use of Intravenous Lignocaine for Radiotherapy-Induced Brachial Plexopathy

Radiotherapy-induced brachial plexopathy (RIBP) is a rare but debilitating complication of breast cancer treatment. There is limited information available on the effective treatments for this condition. We present the case of a 68-year-old female with well-controlled schizophrenia and a history of breast cancer who was referred to our pain management clinic for dysesthesia in the left upper limb secondary to RIBP. The patient exhibited a remarkable response to intravenous (IV) lidocaine infusion, with near-complete resolution of her symptoms. This case highlights the potential of IV lidocaine infusion as a valuable component of a multimodal strategy for managing RIBP.
