Epstein-Barr virus - associated acute acalculous cholecystitis in an adult.

BACKGROUND: Gallbladder involvement during primary Epstein-Barr virus (EBV) infection in adults is rare. CASE REPORT: We report the case of a 29-year-old female with acute acalculous cholecystitis associated with EBV infection. The patient was successfully treated with conservative therapy. CONCLUSIONS: Clinicians should be aware that acute acalculous cholecystitis may be present during viral infection, and surgical treatment is unnecessary in almost all cases.
