Abstract
Neoplastic diseases affecting the brachial plexus are categorized into two forms, primary brachial tumors
and secondary neoplastic disease. Primary brachial plexus tumors are considerably less common than the
secondary forms and are usually benign. Whereas secondary neoplastic disease of the brachial plexus is
unfortunately the most common form of brachial plexus tumor and all types are malignant. The two major
sources of these tumors arise from primary or metastatic disease to the upper lobe of the lung and breast
tissue. Additionally skin, pancreas, larynx, colon, urinary bladder and testis were reported as the sources.
Herein we report a rare case of the lower trunk brachial plexopathy induced by metastatic nasopharyngeal
cancer, which was confirmed by tumor biopsy.
