Congenital dermal sinus is a type of occult spinal dysraphism. It is a result of incomplete separation of the cutaneous ectoderm from neural ectoderm. MRI can aid in identifying the subtype of spinal dysraphism however, surgery is always recommended to dissect the intradural component.

We describe two pre-term infants with incidental findings of non-occlusive aortic thrombi in multiple segments of the aorta. As the infants were extremely pre-mature and due to the high risk of associated medical and surgical treatment complications with intervention, a shared decision was made with the parents to follow the thrombi conservatively. At the time of the report, both the infants were growing well and clinically stable with no signs of cardiovascular compromise.
