Crohn's colitis-induced myocarditis.

Myocarditis can be idiopathic or arise in response to numerous systemic insults. Myocarditis occurring in the setting of an exacerbation of inflammatory bowel disease is a rare extra-intestinal manifestation of both ulcerative and Crohn's-related colitis. Here, we present a unique case of a 56-year-old female patient presenting with an acute Crohn's colitis flare that was eventually complicated by myocarditis. Our case is unique in that we clearly delineate the clinical course and development of myocarditis in a patient with focal myocardial inflammation in a pattern that is atypical for myocarditis. <Learning objective: To illustrate the clinical course and resolution, along with cardiac magnetic resonance imaging and echocardiographic findings, of Crohn's-induced myocarditis.>.
