Colonoscopy linked to isolated Enterococcus faecalis pulmonary valve endocarditis mimicking pneumonia and neoplasm.
Case Report (n=1)
Highlights that isolated pulmonary valve endocarditis can occur following invasive healthcare procedures like colonoscopy, even in structurally normal hearts, and may mimic pneumonia or neoplastic lesions.
Consider isolated pulmonary valve endocarditis after colonoscopy even in normal hearts; case report leaves open prophylaxis questions.
Isolated pulmonary valve endocarditis (PVE) is a rare condition. Known risk factors in previous case reports were intravenous drug abuse and congenital heart disease. Epidemiology of PVE has been changing. It is now being reported specially following invasive healthcare-related procedures even in patients with structurally normal heart. Vast majority of patients present with respiratory symptoms and diagnosis of endocarditis may be challenging unless there is high index of suspicion. Various microorganisms had been isolated as aetiological agents; however, Enterococcus faecalis is being increasingly isolated. PVE mostly managed conservatively with intravenous antibiotics with option for surgical intervention in specific situations. We present a patient with isolated PVE due to E. faecalis following colonoscopy and polypectomy with predisposing risk factor of alcohol excess, mimicking clinically as pneumonia and radiologically as a neoplastic lesion.

Reza et al. (2018) conducted a case report in Isolated pulmonary valve endocarditis (n=1). Intravenous antibiotics was evaluated. A patient presented with isolated pulmonary valve endocarditis due to Enterococcus faecalis following colonoscopy and polypectomy, mimicking pneumonia and a neoplastic lesion.
