  Chromosome 18 trisomy is a chromosomal disorder due to the presence of an extra 18 chromosome, mosaic trisomy, or partial 18q trisomy. The prevalence of live births is estimated at 1: 6000-1: 8000. The ultrasound is vital for the suspicion of chromosome 18 trisomy, especially when the changes refer to the clenched fists with overlapping fingers. However, the diagnosis of certainty is still the karyotype because, in some cases, changes may not be seen on ultrasound examination. We report a case of a 39 years-old woman perform an obstetric ultrasound at about 22 weeks showed the “lemon head” sign and constantly clenched fists of the fetus during the exam, suspecting Edwards Syndrome. After birth, at physical examination, the fists clenched with the fingers of both hands. The karyotype confirmed the trisomy of chromosome 18.
