Abstract
BACKGROUND

Although extraintestinal manifestations of inflammatory bowel disease (IBD) are well documented, myocarditis has only rarely been reported as an extraintestinal manifestation, and it can be fatal. The various clinical presentations and causes of myocarditis in IBD patients complicate making a correct and timely diagnosis.

CASE SUMMARY

Here we report a 15-year-old boy who presented with myocarditis as the initial presentation of a relapse of ulcerative colitis. In reviewing the literature for cases of myocarditis complicating IBD, we found 21 other cases, allowing us to expand our understanding of the clinical presentation, diagnosis, management, and outcomes of this rare condition. The most frequent diagnostic clues for myocarditis in IBD patients are dyspnea, chest pain, tachycardia, raised cardiac biomarkers, and abnormalities on trans-thoracic echocardiography. Additionally, we discuss the etiology of myocarditis in IBD patients, which include an extraintestinal manifestation, the adverse effects of mesalamine and infliximab, selenium deficiency, and infection, to help provide a framework for diagnosis and management.

CONCLUSION

Myocarditis as an extraintestinal manifestation of IBD can be life-threatening. Trans-thoracic echocardiogram and cardiac magnetic resonance may assist its diagnosis.

Core Tip: While the extraintestinal manifestations (EIM) of inflammatory bowel disease (IBD) are well documented, myocarditis as an EIM of IBD is rare. Here we present the case of a 15-year-old boy who presented with myocarditis as the initial presentation of a relapse of ulcerative colitis. The case was unusual in that: (1) While the gastrointestinal symptoms were mild, the endoscopic severity was severe; and (2) He only had mild cardiac symptoms and minimal ventricular dysfunction except for acute chest pain. We therefore propose that cardiovascular manifestations of IBD may be more common than clinically documented, since they may remain undiagnosed.
