We reported two cases of Schwannoma in the brachial plexus. A 51-year-old female and a 66-year-old male presented with a mass in the right lateral neck with pain in the right upper limb at palpation. MRI scans showed that the masses were neurogenic tumors originating from the right brachial plexus in both cases. We resected these tumors, which were encapsulated with enucleation. These tumors proved to be Schwannoma of Antoni A and Antoni B type on histological examination. Postoperative complications appeared in both cases. One had pain in the right upper limb at the C6 level, which improved in 16 months, and the other had disturbance in right limb elevation, which gradually improved in 5 months.
Key words : Schwannoma, brachial plexus, MRI
