The administration of botulinum toxin into the piriformis muscle is one of the treatment options for piriformis syndrome. This relatively controversial clinical entity involves symptoms explained by an increased tone of the piriformis muscle, with some of them being related to the close anatomical relationship of this muscle with the sciatic nerve. Physiotherapy and lifestyle measures, followed by the use of analgesics and muscle relaxants, play an important role in treating piriformis syndrome; in the case of failure of a previous treatment, the administration of a local anaesthetic or botulinum toxin is considered. In order to precisely target the injection into this relatively deeply embedded muscle, the administration can be done under ultrasound guidance. The aim of the article is to introduce the technique of such administration; we describe the administration of botulinum toxin in our patient who is then presented in a short case report.
