Case report

This was a 22-year-old woman (G2P1), with unremarkable history, referred to our antenatal unit at 32 weeks of gestation, due to unilateral femoral hypoplasia. Her previous ultrasonographic exam at 24 weeks was reported to be normal.

Our examination found unilateral curved and shortened right fetal femur. Left femur was normally shaped and concordant with expected biometry. No other anomalies were found and so the diagnosis of unilateral proximal femoral hypoplasia was supposed.

A spiraled CT scan was done, confirming the same findings (right femur 61 and the left one 71 mm|. The rest of the skeleton was normal. Amniocentesis was also done, revealing normal karyotype (46, XX).

The neonate was born in term and the finding was confirmed.
