Cloacal Exstrophy

Etiology: Failure of lower abdominal wall to close
Imaging:
— Anterior abdominal wall defect leads to exposed bladder and cecum (cloaca)
— Diastasis of symphysis pubis
DDX:
Complications:
Treatment:
Clinical:
— Seen in both males and females
— Larger defect than bladder exstrophy
— Omphalocele-Exstrophy of cloaca-Imperforate anus-Spinal defects (OEIS) syndrome

Radiology Cases of Cloacal Exstrophy

AXR of cloacal exstrophy — AXR AP shows diastasis of the symphysis pubis and multiple spinal segmentation defects while the AXR lateral shows a small amount of bowel herniated anterior to the abdomen and inferior to the umbilicus along with a large skin covered spinal dysraphism posteriorly and a radioopaque marker being held in place over where the anus should be.

AXR of cloacal exstrophy — AXR shows diastasis of the symphysis pubis, multiple loops of bowel outside the contour of the abdomen inferiorly, and multiple segmentation anomalies in the lower lumbar spine and sacrum.

Clinical Cases of Cloacal Exstrophy

Clinical image of cloacal exstrophy — Clinical image (left) shows the umbilical stump superiorly and inferior to it is an anterior abdominal wall defect with bladder and cecum herniated through it. Clinical image (right) also shows the skin covered spinal dysraphic defect posteriorly.
