The perineural administration of alcohol or phenol results in protein denaturation and, consequently, neurolysis. This can produce long-lasting analgesia, with a duration of 3–6 months. Although neurolytic blocks for the brachial plexus have been described in multiple review articles and textbooks, they are rarely performed. As such, little is known about the efficacy and adverse effect profile of this commonly described treatment. In this article, we report the outcomes of a patient who underwent a left brachial plexus neurolytic block for the management of upper limb pain arising from a malignant peripheral nerve sheath tumor.
