Infectious mononucleosis is a common in the pediatric population. Its clinical presentation is rather stereotyped in older children and adolescents, with symptoms made of moderate to high fever, sore throat, fatigue, and lymphadenopathy. Biologically, lymphocytosis, and a mild rise in liver function tests are usual. We report a case of acute acalculous cholecystitis as the initial presentation of infectious mononucleosis in a 12-year-old girl whose main presenting complaints were upper abdominal pain and fever. The diagnosis was confirmed by positive Epstein-Barr virus serology and the typical gallbladder appearance on the abdominal ultrasound. Clinicians are reminded of the existence of this association that, we believe, is likely more frequent than thought earlier. Patients' outcome is spontaneously favorable under supportive therapy alone. [ABSTRACT FROM AUTHOR]
