The antenatal sonographic visualization of cloacal dysgenesis
I. M. Lande and E. F. Hamilton
Hydronephrosis associated with a septated cystic structure in the fetal
pelvis in the absence of an otherwise identifiable fetal bladder should
alert the sonographer to the possibility of a persistent cloaca. Problems
associated with compromised urinary tract drainage and the associated
oligohydramnios occurring early in gestation as well as frequent
association of anomalies with other organ systems must be addressed.
Squamous epithelia in fetal bladder aspirate is further supportive evidence
for the diagnosis.
