Prenatal Diagnosis of Ectrodactyly in the First Trimester by Three-Dimensional Ultrasonography.

چکیده
Introduction Ectrodactyly, also known as split hand/foot malformation, is a rare developmental abnormality of the limbs that consists of absent central digits, a deep median cleft, and fusion of the remaining lateral digits, ultimately producing clawlike extremities. This case represents one of the earliest reported diagnoses of this anomaly to utilize three-dimensional (3D) ultrasonography. Case A nulliparous woman presented at 13 weeks of gestation for first-trimester aneuploidy screening. On two-dimensional (2D) imaging, she was noted to have a fetus with a shortened right upper limb and a malformed right hand with no clearly visualized digits. The anomaly was then further evaluated with both transabdominal and transvaginal 2D and 3D ultrasonography with postprocessing visualization, revealing absent central digits. Neither the patient nor her husband reported any personal or family history of skeletal or other structural malformations. Discussion Fetal limb abnormalities are being encountered at increasingly earlier gestational ages due to improvements in image quality and expanded use of ultrasound in the first trimester. Early identification of fetal limb malformations without a definitive diagnosis or a clear pattern of inheritance can present a challenging clinical scenario. Patients may opt for earlier termination of pregnancy rather than wait for additional information to guide decision-making.

We present our experience in the contribution of three-dimensional ultrasonography, using the rendering mode, to the prenatal diagnosis of congenital anomalies including neurological defects (acrania/anencephaly, encephalocele, holoprosencephaly), facial anomalies (cyclopia and facial clefts), abdominal wall defects (omphalocele and gastroschisis) and defects of extremities (fetal muscle-skelet...

Diagnosis of sacrococcygeal teratoma using two and three-dimensional ultrasonography: two cases reported and a literature review.
The occurrence of a fetal tumor is rare, 50% of all fetal tumors being sacrococcygeal teratomas. Prenatal diagnosis of this condition is important for the monitoring of the affected fetuses and for establishing the mode and time of delivery. We describe two cases of fetal sacrococcygeal teratoma diagnosed by 2D- and 3D-ultrasound. Three-dimensional ultrasound proved to be useful both in the dia...
