Nerve plexus metastases
Carcinomas of the lung or breast are the most common sources of brachial plexus metastases, whereas lumbosacral plexus metastases most often arise from primary pelvic tumors or lymphoma. Local and radiating pain is the most common presenting symptom of nerve plexus metastasis, eventually followed by motor and sensory deficits. MRI is fairly sensitive and specific in diagnosing nerve plexus metastases.
