Summary
Thanatophoric dysplasia, a severe skeletal disorder, was diagnosed prenatally using ultrasound. Postnatal examinations confirmed the diagnosis, highlighting the importance of routine screening for fetal malformations.
Area of Science:
- Medical Genetics
- Prenatal Diagnosis
- Skeletal Dysplasias
Background:
- Thanatophoric dysplasia is a severe lethal skeletal disorder.
- Prenatal diagnosis of skeletal dysplasias can be challenging.
- Ultrasound plays a crucial role in identifying fetal anomalies.
Purpose of the Study:
- To describe a case of antenatally diagnosed thanatophoric dysplasia.
- To emphasize the role of ultrasound in early detection of fetal malformations.
- To discuss the etiology and diagnostic challenges of thanatophoric dysplasia.
Main Methods:
- Antenatal diagnosis using ultrasound to detect narrow thorax, pulmonary hypoplasia, and macrocephaly.
- Exclusion of other chondrodysplastic tetramicromelia syndromes.
- Postnatal confirmation through radiological, anatomical, and histological examination.
- Literature review for etiological discussion.
Main Results:
- Prenatal diagnosis of thanatophoric dysplasia was achieved via ultrasound.
- Postnatal investigations confirmed the antenatal diagnosis.
- Significant hydramnios was noted, raising suspicion of fetal malformation.
Conclusions:
- Routine ultrasound screening is vital for detecting fetal malformations like thanatophoric dysplasia early in pregnancy.
- Autosomal recessive inheritance is suggested as a possible etiology.
- Early and accurate diagnosis aids in management and genetic counseling.
