neuralgic amyotrophy

(redirected from brachial plexitis)

neu·ral·gic a·my·ot·ro·phy

a neurologic disorder, of unknown cause, characterized by the sudden onset of severe pain, usually about the shoulder and often beginning at night, soon followed by weakness and wasting of various forequarter muscles, particularly shoulder girdle muscles; both sporadic and familial in occurrence with the former much more common; often preceded by some antecedent event, such as an upper respiratory infection, hospitalization, vaccination, or nonspecific trauma; usually attributed to a brachial plexus lesion, because the nerve fibers involved are most often derived from the upper trunk.

A neurologic disorder of unknown cause, characterized by the sudden onset of severe pain, usually about the shoulder and often beginning at night, soon followed by weakness and wasting of various forequarter muscles, particularly shoulder girdle muscles; both sporadic and familial in occurrence with the former much more common; often preceded by some antecedent event, such as an upper respiratory infection, hospitalization, vaccination, or nonspecific trauma; usually attributed to a brachial plexus lesion, because the nerve fibers involved are most often derived from the upper trunk, but actually multiple proximal mononeuropathies.
Synonym(s): shoulder-girdle syndrome.

In our case, the diagnosis of a brachial plexitis secondary to HZ was established based on the development of weakness following the occurrence of herpetic skin lesions on the left shoulder, findings from the cervical, cranial, and left shoulder MRI, a failure to explain the weakness in the left arm, and demonstration of the involvement of the upper and middle trunks of the brachial plexus in the left shoulder.
