Prenatal diagnosis of fibular aplasia‐tibial campomelia‐oligosyndactyly syndrome: Two case reports and review of the literature

Abstract

Fibular aplasia-tibial campomelia-oligosyndactyly also known as FATCO syndrome is a rare condition characterized by fibular aplasia, shortening and anterior bowing of the lower limb at the tibia with overlying soft tissue dimpling and oligosyndactyly. Its etiology is currently unknown, but there is a male predominance. There are less than 30 cases reported in the literature but only three with prenatal diagnosis. We report two cases of FATCO syndrome with prenatal lower limb malformation diagnosis. Identification of the ultrasound findings of this condition in the prenatal stages allows an adequate parental counselling regarding the clinical features, prognosis, and potential treatments.
