Abstract

Peroneal neuropathy presenting at birth is a rare disorder. Although neonatal mononeuropathies may be related to obstetrical complications, prenatal mechanisms should be also considered. We describe an infant who was born at term by cesarean section due to breech presentation with a unilateral footdrop. Lack of compound muscle action potential in the peroneal nerve and denervation potentials confined to the tibialis anterior and the extensor hallucis longus muscles in the electrophysiological studies on the fourth day of life strongly suggest an isolated peroneal neuropathy of intrauterine onset. Early and sequential electrodiagnostic studies will be important to provide better temporal and pathophysiologic definitions, the better timing of onset and prognosis for mononeuropathies presenting in newborn infants.

출생시에 나타나는 신생아 종아리신경병증은 아직 국내에는 보고된 적이 없는 매우 드문 질환으로, 대부분이 자연 치유되는 양성 경과를 취한다. 신생아의 홑신경병증은 대개 산과적 합병증이지만, 출생 전 원인도 고려하여야 한다. 저자들은 볼기태위로 인해 제왕절개술로 만기 태어난 신생아에서 발견된 발처짐을 보고한다. 생후 4일째 시행한 전기생리학적 검사에서 종아리신경의 복합근육활동전위 소실과 앞정간근과 긴엄지폄근의 탈신경전위가 관찰된 것으로 미루어 자궁 내에서 발병한 종아리신경병증으로 추정한다. 조기에 전기생리학적검사를 시행하고 추적검사를 하면 발병시기와 병리적 기전 및 예후를 판단하는데 도움이 된다.
