Nephroblastoma vs. Obstructive Ileus , Hirschsprung´s Disease
Left picture: A large abdomen may have different causes; in the reported case the abdominal cavity was occupied by a huge mass without clinically recognizable limits. The diagnosis is a very large nephroblastoma. Right picture: Although an abdominal tumor can be considered easily, the abdomen is tense on palpation and sounds tympanic on percussion, meaning that at least part of the volume is caused by an increase in air content of the intestine, or by free air. Based on a short postnatal history with signs of ileus and a plain abdominal x-ray in upright position, the diagnosis is an ileus in the newborn following Hirschsprung´s disease.
Left picture: Young infant with a very large belly. The abdomen is projecting to both sides and differs from the relatively small chest. Right picture: Newborn with a very large abdomen which is protruding and hindering respiration.
