Diagnosis of femoral hypoplasia–unusual facies syndrome in the fetus

Abstract

Femoral hypoplasia-unusual facies syndrome (FHUFS) is a rare condition characterized by a variable degree of unilateral or bilateral femoral hypoplasia associated with facial clefting and other minor malformations. The prenatal diagnosis of this condition is possible, but so far has been reported prospectively in only two cases. We review all cases of FHUFS reported in the literature and also describe three cases detected prenatally in the mid-trimester, underlining the variable expression of the syndrome. The reported association with maternal diabetes mellitus and differential diagnosis with other syndromes characterized by femoral hypoplasia are also discussed.
