Rotavirus enteritis is an infectious disease of the small bowel caused by an RNA reovirus. It is manifested by cytotoxic diarrhea [1]. Rotavirus is the most common viral cause of enteritis (incidence 15-35%) [2]. In infants and children with abdominal pain and diarrhea, ultrasonography is the diagnostic study of choice, and its use has increased significantly in young patients. We describe two cases in which portal-vein gas was detected on abdominal ultrasound scans in children with severe dehydration secondary to rotavirus gastroenteritis, which resolved rapidly after treatment.
