SWV is related to the degree of liver fibrosis in children, and may be a non-invasive alternative to biopsy.

US-guided PLB in children is a safe and efficient method to achieve a specific diagnosis in liver disease.

ARFI analysis seems to be influenced by age, depth, and lobe of measurements. A mean SWV value of 1.07 ± 0.10 m/s for healthy paediatric population with the possibility of reaching 1.12 m/s in the case of younger children was found. ARFI values were more consistently obtained analysing right liver lobe and depths lower than 5 to 6 cm.

ARFI may serve as a potential method for assessing significant fibrosis in pediatric patients with liver transplant, particularly in combination with AST/ALT ratio index.

Primary epiploic appendagitis is an inflammation of the epiploic appendages occurring due to ischemic infarction as a result of appendage torsion or spontaneous thrombosis usually affecting patients from second to fifth decades, being more common in women and obese patients. It is a self-limiting entity with clinical features similar to other inflammatory abdominal processes and sometimes not remembered at clinical examinations. The awareness of this entity and its correct identification on imaging examinations could prevent unnecessary surgery. The authors present a clinical case complemented with ultrasound and CT images of this entity.
