We report a case of prenatally diagnosed McKusick-Kaufman syndrome in
a 28-year-old patient who was investigated because of feta I ascites a
t the 28th week of gestation. Ultrasound examination showed a female f
etus with postaxial hexadactyly of both upper extremities, massive asc
ites, hyperechogenic enlarged kidneys and three abdominal cysts, repre
senting dilated uterus vagina and bladder, indicating McKusick-Kaufman
syn drome to be likely. Chromosomal analysis revealed a normal karyot
ype. Because of progressive fetal skin edema, elective Cesarean sectio
n was performed at the 31st week of gestation. A 2200-g female with Ap
gar scores of 6/8/9 was delivered. Postnatal examination confirmed the
antenatal diagnosis. In addition, an atrial septal defect and congeni
tal intestinal aganglionosis were found. Surgical urogenital reconstru
ction was performed at 6 weeks of age with good results.
