Patient had no contributive personal or. The following images show a case of otocephaly, agnathia, holoprosencephaly diagnosed in a 12 weeks old fetus. Images 1, 2: 12 weeks of pregnancy; the images show transverse scans of the fetal skull with holoprosencephaly and abnormally shaped and positioned fetal ears During the study period, 378 women considered at risk for chromosomal defects underwent first‐trimester CVS at a median gestational age of 12 weeks (range, 11-14 weeks). Three fetuses had a diagnosis of holoprosencephaly at gestational ages ranging from 12 weeks 4 days to 13 weeks 5 days age of 12 weeks (range, 11-14 weeks). Three fetuses had a diagnosis of holoprosencephaly at gestational ages ranging from 12 weeks 4 days to 13 weeks 5 days. In none of the cases was it possible to identify the butterfly sign (Figures 2 and 3). Focused examination of the fetal brain in these cases showed the charac

A 34-year-old woman (gravida 1, para 0), was referred at 18 weeks of gestation with a ultrasound diagnosis of alobar holoprosencephaly. The ultrasound demonstrated a small head, hypotelorism, primitive ventricle, fused thalami, absent falx and septum pellucidum, cleft lip and palate. All of them confirmed posteriorly by MRI at 20 weeks At the fetal Medicine review, a morphological ultrasound was performed with 12-week CRL (61 mm). Ductus venosus with absence of a wave, the heart can not be evaluated in detail due to limitation of BMI (poor transmission). In the CNS assessment, image compatible with semilobar holoprosencephaly and flat profile with hypoplastic / absent nasal bone As with most cerebral structural congenital abnormalities, holoprosencephaly is visible on all modalities, but in general is identified on antenatal ultrasound, and best characterized by MRI. On antenatal ultrasound, there may be also evidence of polyhydramnios , a secondary feature due to impaired fetal swallowing However, the prevalence was dependent on the fetal CRL and the content of the exomphalos. GA indicates gestational age; MA, maternal age; and NT, nuchal translucency. The scan of 12 weeks revealed the presence of brain abnormalities. and V.D.).

Holoprosencephaly may be associated to other midline defects and may be part of an aneuploidy such a trisomy 13 (Patau's syndrome). Lack of prosencephalus division at a later stage either leads to semilobar holoprosencephaly or lobar. Holoprosencephaly can be diagnosed even in the first trimester after 11-12 weeks 7), though mild forms may not be reliably detected prenatally..

Patient concern: The main knowledge added by this case is the late ultrasound diagnosis and chromosomal analysis that revealed a very rare abnormality (45X/46,XX/47,XX) with mosaicism at chromosome 18 When holoprosencephaly is found on an prenatal ultrasound, a high-resolution ultrasound is used to determine the presence of other anomalies. If there is a family history of holoprosencephaly, the mother may get a genetic testing done. This may be done by extracting DNA cells from the amniocentesis at about 15 to 18 weeks of gestation
