Congenital rubella syndrome with viral esophagitis. An electron microscopic study

Duodenal stenosis, a new finding on congenital rubella syndrome: Case description and literature review

Congenital rubella syndrome (CRS) continues to represent a public healthcare problem although an effective vaccination program. Gastrointestinal involvement is rather infrequent and the association of CRS with duodenal stenosis has been never reported. In this study a case of CRS with duodenal diaphragm is reported and the gastrointestinal diseases described in association with CRS are reviewed. A 10-month-old child affected by CRS with congenital hearth disease, perceptive deafness and microcephaly, was admitted because of vomiting and failure to thrive. An upper endoscopy demonstrated dilated proximal duodenum and a perforated diaphragm in the second segment of the duodenum. Endoscopic membranectomy was therefore performed. Two months later the patient was submitted to a further endoscopic evaluation that showed a partial diaphragm persistence and a second excision was performed. Follow-up one year after the first treatment showed good clinical conditions, reasonable physical growth and disappearance of vomiting. In conclusion we report the first case of CRS in association with duodenal stenosis. Duodenal stenosis in the absence of other intestinal localizations may be due to rubella capacity of infecting only small numbers of fetal cells but we cannot exclude that the duodenal stenosis in our patient be only a casual association.
