Immune checkpoint inhibitors (ICIs) have improved the management and the prognosis of patients with cancer but are associated with an increased risk of toxicities that can affect every organ. ICI-associated myocarditis has a low incidence (< 1%) but a high fatality rate (30%-50%). Herein we report a patient treated with ICI admitted for suspicion of myocarditis. Cardiac magnetic resonance imaging (cMRI) was normal. An endomyocardial biopsy (EMB) was in favour of ICI-related myocarditis with cardiac lymphohistiocytic infiltrate. This case highlights the role of a systematic evaluation with electrocardiography and troponin and the potential value of EMB in patients without a suggestive cMRI.
免疫检查点抑制剂（ICI）改善了癌症患者的治疗和预后，但会增加影响各个器官的毒性风险。ICI相关的心肌炎发病率低（<1%），但死亡率高（30%-50%）。在此，我们报告一例接受ICI治疗的患者因疑似心肌炎入院。心脏磁共振成像（cMRI）结果正常。心内膜心肌活检（EMB）支持与ICI相关的心肌炎，伴有心脏淋巴细胞组织细胞浸润。该病例突出了心电图和肌钙蛋白系统评估的作用以及EMB在cMRI无提示意义患者中的潜在价值。
