Brachial plexus schwannomas

Abstract

Schwannoma is a rare tumor that can be found in the brachial plexus. Despite the fact it is benign it can cause inflammatory reaction or compression of the nerves’ fascicles causing altered muscular or sensitive performance of the upper limb. Diagnosis of Schwannoma in the brachial plexus is difficult due to confounding interpretation with other lesions, that makes important magnetic resonance imaging (Mri) and histopathological examination for a complete diagnostic assessment. Surgical treatment is challenging, but, currently, microsurgical approach using the microscope, microsurgical tools and skills allow tumor removal with an acceptable risk of injury to neurovascular structures. Schwannomas of the brachial plexus are curable lesions and the use of precise surgical techniques allows these tumors to be removed with minimal morbidity.
