Abstract

 

Brachial plexopathy secondary a malignant tumor of the peripheral nerve sheath.Introduction. Malignant peripheral nerve sheath tumor (MPNST) are sarcomas that are rarely located in the upper limb. Clinical case. We present a 31- year-old woman with progressive dysesthesia and weakness of the left upper limb. The neurophysiological study showed damage in the left brachial plexus. A soft tissue mass that was invading the plexus was observed in the magnetic resonance image. The anatomopathological study was compatible with MPNST diagnosis. Conclusions. Intrinsic tumors of the brachial plexus are uncommon. A MPNST is an extremely aggressive mesenchymal tumor that is seldom rooted in the brachial plexus.

Key words: Brachial plexus. Brachial plexopathy. Neoplasm. Malignant tumor. Peripheral nerve sheath.
