Transient protein-losing gastropathy (Menetrier's disease) in childhood.

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.
