Case report

Patient was presented to our department for the ultrasound examination.
We discovered the following findings:

• Anhydramnios
• Lung hypoplasia
  
• Dilated urinary bladder, no "keyhole sign"
  
• Dilated bowel with echogenic content, possibly colovesical fistula
  
• Sacral agenesis

Pregnancy was terminated based on the ultrasound findings. Clinical examination of the fetus showed grossly protuberant abdomen, no genitourethral or anal external opening. Final diagnosis was urorectal septum malformation sequence.

Images 1,2: Image 1 shows dilated bowel with echogenic content. Image 2 shows dilated bowel (arrow) and distended urinary bladder (*).



Images 3,4: Image 3 shows a distended bladder. Image 4 shows sagittal view of the abdomen, note sacral agenesis and echogenic bowel content adjacent to the urinary bladder.



Images 5,6: Image 5 shows transverse view of the abdomen, dilated urinary bladder adjacent to the echogenic bowel content and cross section of the kidney. Image 6 shows a sacral agenesis.



Images 7,8: Image 7 shows a cross section of the urinary bladder. Image 8 shows transverse view of the both kidneys, note unilateral pyelectasis and dilation of the urether.
