Two cases of transient protein-losing gastropathy (PLG) or Menetrier's disease in childhood are described. Both cases presented
with an abrupt onset of edema due to hypoalbuminemia and were diagnosed by an upper gastrointestinal series. One of the cases
was further diagnosed and followed by ultrasound. We believe that this is the first description of the ultrasonic picture
of transient PLG in children. In both cases complete recovery was evident after a few weeks.
