Can we prevent splenic rupture for patients with infectious mononucleosis?
Abstract
All patients with infectious mononucleosis should be considered at risk for splenic rupture since clinical severity, laboratory results, and physical exam are not reliable predictors of rupture (strength of recommendation [SOR]: B, case-control study). Clinical evidence indicates that most splenic ruptures occur within 4 weeks of symptom onset, which correlates with ultrasound data showing resolution of splenomegaly by 30 days from symptom onset (SOR: B, case-control study). Given the morbidity and mortality associated with splenic rupture, instruct patients to refrain from vigorous physical activity for 1 month after symptom onset (SOR: C, expert opinion).
