Radiological findings in two patients with cow's milk allergic enterocolitis.

Cow's milk allergic enterocolitis is a common paediatric gastrointestinal disease. However, radiological findings from contrast studies have rarely been reported. We report two Japanese neonate patients with cow's milk allergic enterocolitis with vomiting, bloody stool and unique findings on upper gastrointestinal contrast study. Upper gastrointestinal contrast study showed folds of the small intestine to be thickened, such as in spasm, or ribbon-like cords in both cases. There was also poor passage from the duodenum to the jejunum in one case. In addition, there were spastic findings on lower gastrointestinal contrast study in part of the large colon in one case. Clinicians, including paediatric surgeons, treating neonates with bloody stool and/or vomiting should thus be aware that unique findings on upper and lower gastrointestinal contrast studies may be useful in suspecting cases with cow's milk allergic enterocolitis.

Duodenal atresia with a deletion of midgut associated with left lung, kidney, and upper limb absences and right upper limb malformation.

Duodenal atresia with midgut deletion without abdominal wall defects is extremely rare. The authors report a newborn boy with this disease associated with left pulmonary, kidney, and upper limb absences and a contralateral upper limb malformation. At autopsy, agenesis of the arteries to such organs was confirmed. A fetal vascular disruption is presumed to be the main cause of these anomalies.
