Migration of Self-Introduced Acupuncture Needle into the Brainstem.

Acupuncture-related injuries to the central nervous system are a rare but well-documented occurrence. This report describes the case of a self-introduced acupuncture needle migrating into the brainstem following an initial failed attempt at surgical extraction. The patient displayed no neurological deficits, and the needle was eventually successfully removed under direct vision intraoperatively. We discuss the role of various imaging modalities in pre- and post-operative assessment of penetrating foreign bodies in the brainstem. We also discuss the options available for the management of such foreign bodies, including possible approaches for operative intervention, and the risks involved with both surgical and conservative management.
