摘要

因急性腎臟皮質壞死而造成腎衰竭較少被描述及報告。急性腎臟皮質壞死的特徵為腎臟皮質壞死，但是腎臟髓質依舊完好。通常急性腎臟皮質壞死病人臨床情況都很差，腎臟切片證實有其困難性，因此其他非侵犯性檢查更顯得重要。注射顯影劑的電腦斷層檢查，對於急性腎臟皮質壞死有其特異性發現。我們報告一位31歲的女性，因腦膜炎雙球菌感染造成敗血病，並進而引發急性腎臟皮質壞死。

Acute renal cortical necrosis (ARCN) is a rare cause of acute renal failure characterized by necrosis of the renal cortex with sparing of the renal medulla. Owing to poor clinical condition during the early period of ARCN in most cases, it does not allow renal biopsy which is a gold standard for diagnosis. Therefore, noninvasive diagnostic modalities have been tried and, among them, contrast-enhanced computed tomography (CT) is found to provide characteristic findings. We present a 31-year-old female of meningococcemia with septic shock, who developed oligouria and was diagnosed as ARCN by the specific CT findings without renal biopsy.
