Cirrhosis is the frightening complication of chronic liver disease. Common causes include biliary atresia, a pathology with a poor prognosis in the absence of a prompt diagnosis and therapeutic intervention. We present the case of a patient diagnosed with biliary atresia who underwent Kasai intervention. After an initial period with disappearance of the jaundice and normal color of the stool, the patient reached the stage of decompensated cirrhosis. Among the complications suffered by the patient we mention ascites, esophageal varices, upper gastrointestinal hemorrhage, repeated infections, anemia, rickets, and hepatic osteodystrophy. For this patient, the only long-term therapeutic option remains liver transplantation. Although cases of pediatric patients with an early Kasai intervention and survival with native liver are described, the long-term evolution depends on the occurrence of possible complications and most patients eventually require liver transplantation.

Cytomegalovirus can affect people of all ages, from all geographical areas, regardless their race or the social status. The severity of infection fluctuates from easy to severe, in most cases being asymptomatic. The antiviral therapy is rarely administered, only in selected cases and consists in ganciclovir or sometimes valganciclovir. Most of the patients do not present long-term sequelae from the infection, but for premature infants and children with very low birth weight, complications may occur more frequently than in the general population. We present the case of an infant of three months, diagnosed with cytomegalovirus hepatitis after corroborating clinical data, laboratory and ultrasound results. Evolution is initially favorable towards healing without suggesting the possibility of long-term organ injuries, but after four months, the infant is readmitted to the hospital and is diagnosed with biliary atresia.
