MURCS association is a rare, lethal and unusual constellation of nonrandom findings that includes mullerian duct aplasia, renal aplasia, and cervicothoracic somite dysplasia.1-3 It has been described in 30 patients by Duncan and coworkers2 in 1979, in which report the authors proposed an embryologic cause for these defects.3 Antenatal ultrasonographic findings included a massive, cystic umbilical cord related to a patent urachus, enlarged bladder, single small kidney, and suspicion of urethral obstruction in a fetus of female phenotype.
