We present some images and videos of a second trimester fetus with sacral agenesis. 34 year-old obese patient presented at 23+5 weeks of gestation. Scanning revealed fetus of 22+5 weeks size with sacral agenesis. Subsequently MRI confirmed the findings. The patient was not diabetic (negative OGTT and HbA1c). One little myoma is still visible.

Images 1 and 2: 24th week of pregnancy. Longitudinal scans of the sacral region of the fetus showing missing caudal part - sacral agenesis.
