Recurrent brachial plexus neuropathy in a family with subtle dysmorphic features -- a case of hereditary neuralgic amyotrophy.

Brachial plexus neuropathy is a disorder which usually occurs sporadically, and is characterized by pain and varying degrees of weakness in one or both upper limbs. Some patients experience recurrent episodes. The hereditary form is usually associated with dysmorphic features. We describe a mother and son with recurrent episodes. Despite very slight dysmorphic features, we believe this is a case of the inherited form.
