Crohn's disease and ulcerative colitis are the two major types of inflammatory bowel disease, and affect mainly the gastrointestinal tract but also have extraintestinal sequelae, such as arterial and venous thromboembolism. Thromboembolic complications, particularly pulmonary thromboembolism, can be life threatening and require prompt management with anticoagulants. Conventional vitamin K antagonists have been used for the treatment of thromboembolic complications, but the development of novel oral anticoagulants has shifted the paradigm. We report a case of a 42-year-old female with ulcerative colitis who experienced an acute flare-up due to cytomegalovirus superinfection with pulmonary thromboembolism. She was treated with oral mesalamine, intravenous steroid and ganciclovir and low-molecular-weight heparin, followed by rivaroxaban, a novel oral anticoagulant. Her symptoms resolved after treatment, and no recurrence was noted during a 6-month post-treatment follow-up.
