Abstract
Extreme variability of expression is characteristic of the facio-auriculo-vertebral sequence. Sporadic and familial cases have been reported with obvious etiologic heterogeneity. Most reports in the literature are of clinical cases. The purpose of this paper is to present a fetal autopsy case report of the facio-auriculo-vertebral sequence in association with DiGeorge sequence, Rokitansky sequence, and Dandy-Walker malformation. A standard neonatal autopsy was performed on a macerated female fetus, gestational age 29 wk. External examination of the fetus revealed hypoplastic right face, low-set microtic right ear, and macrostomia. Internal examination showed hypoplastic thymus and lungs, a type I truncus arteriosus, and ventricular septal defect. Both kidneys showed evidence of pelvi-ureteric junction obstruction. The ovaries and fallopian tubes were present with an absent uterus and vagina (Rokitansky sequence). In addition, Dandy-Walker malformation was identified. Microscopically, a single hypoplastic parathyroid gland was noted and there was cystic renal dysplasia. We report the sixth case of the facio-auriculo-vertebral sequence in association with Rokitansky sequence and the first case of this sequence in association with Dandy-Walker malformation. In addition, features of DiGeorge sequence were present.
