Birth palsy in congenital varicella syndrome: A lesson in anatomy

ABSTRACT While brachial plexus palsy sustained due to birth trauma is well known, congenital palsies are decidedly rare. We report such a case caused by congenital varicella syndrome, with associated congenital Horner's syndrome and heterochromia iridis. The surprising juxtaposition of a classic upper plexus palsy and a Horner's syndrome raises points of interest. Similar reports in literature are reviewed, and the genesis of a very characteristic group of findings is discussed.
