Diagnosis of plexopathy relies on proper identification of a pattern in motor and sensory function deficits in the upper or lower extremities.
[1] To rule out confounding conditions such as radiculopathy or myelopathy, an MRI of the cervical or lumbar spine is often obtained.
In the case of a mass lesion causing compression of the brachial or lumbosacral plexus, surgical decompression may be warranted.
In an idiopathic brachial plexopathy, no specific treatment is usually indicated, although there is limited evidence that steroids may hasten recovery.
[7] [8] If a brachial or lumbosacral plexopathy is determined to be caused by diabetes, management includes controlling the patient's blood sugar.
