AANS Online Scientific Sessions: Spine and Peripheral Nerve-The Risk of Peripheral Nerve Tumor Biopsy in Suspected Benign Etiologies

The Risk of Peripheral Nerve Tumor Biopsy in Suspected Benign Etiologies

Video Transcription

Video Summary

The video is a presentation by Dr. Roberto Perez-Román, a fourth-year resident at the University of Miami Neurosurgery Program. He discusses the risk of peripheral nerve tumor biopsy in suspected benign cases. Peripheral nerve sheath tumors, such as schwannomas and neurofibromas, represent about 10% of benign soft tissue neoplasms. Differentiating between benign and malignant tumors can be done based on clinical and radiological grounds. Biopsy is commonly recommended for diagnosis, but it carries a risk of neurological deficits, especially in benign lesions due to potential nerve injury. The study reviewed 151 cases and found that preoperative biopsy increased the risk of new neurological deficits. The presentation emphasizes caution in using biopsy for suspected benign tumors.
