The objective of this study is to demonstrate the potential role of the first trimester ultrasound in diagnosis of holoprosencephaly. Holoprosencephaly may be associated to other midline defects and may be part of an aneuploidy such a trisomy 13 (Patau's syndrome). Holoprosencephaly The incidence of the holoprosencephaly in the first trimester of pregnancy is unknown. Introduction Holoprosencephaly (HPE) is commonly associated with facial malformations. In this subset of fetuses, the evaluation of intracranial anatomy for signs of holoprosencephaly may be more difficult to perform due … First-trimester ultrasound diagnosis of holoprosencephaly: three case reports.

Holoprosencephaly (HPE) is commonly associated with facial malformations. (3,4) We describe a case of holoprosencephaly with proboscis and cyclopia identified at 16-weeks' gesta-tion by 2- (2D) and 3-dimensional (3D) transabdomi-nal US. Figure 5: Alobar holoprosencephaly in the first trimester. Ultrasound examinations were performed by the authors from June 1989 to November 1998, using a convex transabdominal transducer of 3.5 MHz and transvaginal transducer of 5 MHz (Aloka Model 680EX, Tokyo, Japan). An ovum without an embryo is known as: Anembryonic Pregnancy. Ultrasound Obstet Gynecol. Clinical symptoms include vaginal bleeding and rapidly declining beta hCG levels. The arrows indicate the large communication between the cerebral ventricles fused thalami (A) and absence of the butterfly aspect of choroid plexus (B).
