Zusammenfassung:Background Rhizomelic chondrodysplasia punctata (RCDP) is a rare autosomal recessive inherited subtype of a family of congenital anomalies known as chondrodysplasia calcificans punctate (CCP). Given their low rate of occurrence, these cases are highly challenging to diagnose, and because the presence of chondrodysplasia is an indication for legal abortion in Iran, such diagnosis is extremely critical. Case Presentation A 27-year-old white multipara was referred for obstetric ultrasonography at 17 weeks and 6 days of gestation because an ultrasonographic study performed at an outside institution revealed a short femur length. Given the patient’s positive family history of chondrodysplasia, she underwent targeted sonography to check the anomaly of the bone and cartilage. The key finding in the sonography was short bones for gestational age. Conclusion The important clue in this finding was the patient’s family history, which made the gynaecologist request an ultrasound to prevent the birth of a child with a congenital disorder. Genetic tests are usually performed on amniocentesis samples . Because the presence of chondrodysplasia is an indication for legal abortion in Iran, finally, the patient underwent legal abortion after amniocentesis and genetic tests.
