[Infectious mononucleosis (Pfeiffer glandular fever) with membranous angina, nephritis, myocarditis and Guillain-Barré syndrome].

In a 10 year old boy with infectious mononucleosis beginning with membranous tonsillitis, followed by nephritis, myocarditis and Guillain-Barré-Syndrome, all the complications could be managed by symptomatic treatment. With favourable outcome after about 3 months of hospitalisation, he could be discharged with only mild neurologic residuals.
