Shortness of breath in a patient with inflammatory bowel disease.

Cytomegalovirus (CMV) is an important cause of morbidity and mortality in immunocompromised patients. Although immunosuppressive therapy is the mainstay of medical treatment for patients with inflammatory bowel disease, the importance of CMV as a cause of pneumonia in this group is less well recognised. This case report presents a case of shortness of breath, dyspnoea and fever in a 51-year-old man with Crohn's disease on azathioprine and highlights the importance of considering CMV as a cause of pneumonia in this group. 2014 BMJ Publishing Group Ltd.
