AbstractHereditary neuralgic amyotrophy is a rare disorder, characterized by recurrent attacks of pain in a brachial plexus distribution. We report the case of a 12-year-old boy with several attacks of pain and atrophy of the muscles of the shoulders. The age of onset of this disease is variable, most frequently in the second or third decade. Pediatric onsets, during the first decade are rare. The differences between the hereditary neuralgic amyotrophy and the sporadic Parsonage-Turner syndrome are painful recurrent episodes of weakness and similar familial cases. The analysis of several families has shown that hereditary neuralgic amyotrophy phenotype is heterogeneous and two different clinical courses can be discerned. Recent evidence indicates that HNA is genetically heterogeneous. Pathophysiology of the disease remains unclear, so the treatment is not clearly established.
