We present a case of semilobar HPE associated with distal limb defect which was detected at 12 weeks of gestation. Normally, the forebrain is formed and the face begins to develop in the fifth and sixth weeks of human pregnancy. The diagnosis was based on two sonographic criteria: first, the intra- 45. The condition also occurs in other species.

Another first trimester abnormalities: Omphalocele: Is a birth defect of the abdominal wall. Key words: HOLOPROSENCEPHALY, HYPOTELORISM, PROBOSCIS, PRENATAL ULTRASOUND ABSTRACT We present three cases of fetal holoprosencephaly diag-nosed by transabdominal and transvaginal ultrasound ex-aminations at 10 and 13 weeks’ gestation. Emotional implications could have been less severe if the patient underwent regular ultrasonography allowing a diagnosis in the first or early second trimester. Holoprosencephaly may be associated to other midline defects and may be part of an aneuploidy such a trisomy 13 (Patau's syndrome). PubMed PMID: 18956427. The fetus had a crown-rump length of 60 mm (12 weeks–4 days), had nuchal translucency thickness of 1.5 mm. One-third of first-trimester fetuses with a sonographic diagnosis of holoprosencephaly had a biparietal diameter that was smaller than expected for crown-rump length.
