Epipericardial fat necrosis (EPFN) is a relatively rare cause of acute chest pain, with only five pediatric cases having been reported in the English-language medical literature to date. EPFN can be diagnosed based on the clinical symptoms of acute pleuritic chest pain and classic CT features of typically ovoid fatty lesions surrounded by a rim or capsule in the mediastinal or pericardial areas. Previous studies have reported that contrast-enhanced MRI can detect typical fat signal changes in adults with EPFN. We report a pediatric EPFN case diagnosed using gadolinium-enhanced MRI. Thus, contrast-enhanced MRI may be used to confirm EPFN in the differential diagnoses of the causes of acute chest pain.
心包外脂肪坏死（EPFN）是急性胸痛相对少见的病因，迄今为止英文医学文献中仅报道了5例儿科病例。EPFN可根据急性胸膜炎性胸痛的临床症状以及纵隔或心包区域典型的椭圆形脂肪病变周围有边缘或包膜的经典CT特征进行诊断。既往研究报道，对比增强MRI可检测出成人EPFN典型的脂肪信号变化。我们报告1例使用钆增强MRI诊断的儿科EPFN病例。因此，在急性胸痛病因的鉴别诊断中，对比增强MRI可用于确诊EPFN。
