We report five children with aberrant thymus, four of whom presented with an upper suprasternal mass and one with a lateral neck mass. Awareness of this entity, together with knowledge of its variable presentation, is essential for unnecessary surgery to be avoided. US should be the initial diagnostic approach and occasionally leads to the correct diagnosis.

Sonographic measurement of the abdominal esophagus length is highly diagnostic for GER in neonates and infants. In neonates, it can also indicate GER severity. Hiatal hernia is associated with a significantly shorter abdominal esophagus.

The sonographic appearances of two children with appendiceal intussusception and two others with appendiceal-intestinal intussusception are described. All the cases were documented by barium enema and surgically confirmed.

Enlarged lymph nodes in the intussusception are mainly found in patients with a current or recent history of gastroenteritis and decrease the overall hydrostatic reduction rate.
