Gallbladder wall thickening on bedside ultrasound in a child with Epstein-Barr virus infection.

Gallbladder wall thickening (GBWT) is rarely reported in children with acute Epstein-Barr virus (EBV) infection. We present a child with EBV infection who was found on point-of-care ultrasound to have GBWT without signs of cholecystitis that subsequently resolved without intervention. We expect the proliferation of mobile and handheld sonography to increase the number of bedside examinations in febrile children. This, in turn, will increase the incidence of GBWT found in patients with EBV infection and without right upper quadrant pain. Prospective study is needed to define the incidence of GBWT in children with EBV infection.
