Presentation This neonate had an antenatal diagnosis of an intraabdominal cyst. The cyst had been decompressed antenatally by aspiration which yielded a yellowish tinged fluid, however the cyst filled up again. This is the scan performed on day 3 after birth.

Differential Diagnosis Ileal duplication cyst in a neonate
 
Final Diagnosis Ileal duplication cyst in a neonate
 
Follow Up A contrast enema was performed, which showed the bowel to be intrinsically normal but compressed. A duplication cyst arising from the distal ileum was seen at surgery. The cyst shared a common wall with the corresponding portion of the ileum and was resected along with a segment of the ileum. Additionally malrotation of the bowel loops was seen.
