    Abstract:
    OBJECTIVE: Skeletal dysplasia with bowing long bones is a rare group of multiple characterized congenital anomalies. MATERIALS AND METHODS: We introduce a simple, practical diagnostic flowchart that may be helpful in identifying the appropriate pathway of obstetrical management. RESULTS: Herein, we describe four fetal cases of bent bony dysplasia that focus on ultrasound findings, phenotype, molecular tests, distinctive X-ray features, and chondral growth plate histology. The first case was a typical campomelic dysplasia resulting from a de novo mutation in the SOX9 gene. The second fetus was affected by osteogenesis imperfecta Type II carrying a mutation in the COLA1 gene. The third case was a rare presentation of campomelic dysplasia, Cumming type, in which SOX9 examination was normal. Subsequently, a femoral hypoplasia unusual facies syndrome is also discussed. CONCLUSION: Targeted molecular tests and genetic counseling are required for supplementing ultrasound imaging in order to diagnose the correct skeletal disorders.
