Acute perimyocarditis is a rare extra-intestinal manifestation in Crohn’s disease which required multimodality imaging to confirm the diagnosis. Here we present a case of acute perimyocarditis as the first presentation of Crohn’s disease. To date, this is the first case presentation reporting the use of 18F-FDG PET/CT Scan for diagnosing such condition. A 25-year-old male presented to our hospital with severe persistent pleuritic sharp left-sided chest pain. This was his second hospital admission in the past 4 months for chest pain and diarrhea. At the first hospitalization, he was diagnosed with viral perimyocarditis and irritable bowel syndrome. Laboratory findings, electrocardiogram, and cardiac magnetic resonance imaging results confirm the diagnostic of perimyocarditis. Virology, bacteriology, parasitology, and autoimmune evaluations were unremarkable. Colonoscopy, colorectal biopsy, and 18FGD PET findings confirmed manifestation of perimyocarditis, Crohn’s disease, and negative for sarcoidosis. Looking at the overall clinical picture and investigation results of colonoscopy, colorectal biopsy findings, as well as multi-modality imaging with echocardiography, 18FDG PET—scan and CMRI, the patient was diagnosed to have perimyocarditis attending Chron’s disease flare up as a rare extra-intestinal manifestation.

多模态成像在诊断继发于克罗恩病的急性心包炎中的作用

急性心包炎是克罗恩病中罕见的肠外表现，需要多模态成像来确诊。在这里，我们提出一例急性心包炎作为克罗恩病的首次表现。迄今为止，这是第一个报告使用 18F-FDG PET/CT 扫描来诊断这种情况的病例报告。一名 25 岁男性因严重的持续性胸膜炎性左侧剧烈胸痛来我院就诊。这是他在过去 4 个月内第二次因胸痛和腹泻入院。在第一次住院时，他被诊断出患有病毒性心包炎和肠易激综合征。实验室检查结果、心电图和心脏磁共振成像结果证实了心包炎的诊断。病毒学、细菌学、寄生虫学、和自身免疫评估不显着。结肠镜检查、结直肠活检和 18FGD PET 检查结果证实了心包炎、克罗恩病和结节病阴性的表现。从结肠镜检查、结直肠活检结果以及超声心动图、18FDG PET-scan 和 CMRI 的多模态成像的总体临床情况和调查结果来看，该患者被诊断为患有心包炎并伴有 Chron 病发作，这是一种罕见的外发疾病。肠道表现。
