Perforation of multiple gastric duplication cysts: diagnosis by sonography.

A case of perforation of multiple gastric duplication cysts is presented. The rarity of this case is based on its multiplicity, its small size, its perforation into peritoneal cavity, as well as on the detection of tiny foci of ectopic pancreatic tissue at the site of perforation. The sonographic appearance and the clinical manifestations are discussed.

New sonographic appearance of hepatic mesenchymal hamartoma in childhood.

We present clinical, radiographic, and sonographic findings in 3 children with hepatic mesenchymal hamartoma, a rare benign tumor of childhood. The presence of round hyperechoic parietal nodules within the cystic spaces of the hamartomas is a new sonographic finding.

Aberrant thymus in infants: sonographic evaluation.

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.
