Neonatal Bowel Obstruction by Pseudolymphoma: A Case Report

Interstitial obstruction in newborn infants can be caused by several factors such as malrotation, meconium plug syndrome, meconium ileus, Hirschsprung's disease, atresia and stenosis. Neonates who have been diagnosed with an interstitial obstruction are in need of immediate treatment; otherwise, they can deteriorate rapidly. Surgery remains the mainstay of treatment in most cases. Pediatric gastrointestinal tumours are very rare, especially in newborn infants. Their management is usually different as compared to adults. We present the case of a newborn infant who was born with interstitial obstruction. At the 31 weeks scan, a significant dilation of the small bowel was observed and the diagnosis of interstitial obstruction was made. When born, the newborn was transferred to a specialised unit and underwent a laparotomy. The findings were consistent with a tumour causing the obstruction; the histology reported this tumour as benign lymphoid hyperplasia. Pseudolymphoma is a very rare cause of fetal interstitial obstruction, and it should be considered in the differential diagnosis.
