Anorectal Malformation Associated with Klippel–Feil Syndrome: A Rare Association

Anorectal malformations (ARMs) are a complex group of malformations associated with various congenital anomalies. Klippel–Feil syndrome (KFS) is characterized by fusion of cervical vertebrae, short neck, torticollis, and/or facial asymmetry and very rarely associated with ARM. In the presence of cervical vertebral anomalies in ARM, one should search for the presence of KFS as an association. If this anomaly is found to be associated, caution is needed during positioning for examination, surgery, during laryngoscopy, and intubation due to risk of neurological damage. We hereby present a very rare association of KFS with ARM with solitary kidney and ipsilateral vesicoureteral reflux.
