The most common site of the congenital duodenal web is the second part. Web distal to the second part of the duodenum is rare. It mimics the windsock deformity. Diagnosis may be missed if accompanying malrotation is present. We hereby report two cases of distal duodenal webs associated with malrotation and challenges in their diagnosis and management.
