Role of Ultrasound for evolving anomalies in Fetus :
Ultrasound (USG) is a cornerstone in diagnosing and monitoring evolving fetal anomalies during pregnancy.
These anomalies may not be evident early but develop or become apparent as the pregnancy progresses. Here’s how USG contributes to their management:
1. Early Screening and Detection
First-Trimester USG (11–14 Weeks):
Detects structural anomalies such as neural tube defects, abdominal wall defects, and nuchal translucency (NT) abnormalities, which may hint at chromosomal or syndromic conditions.
2. Monitoring Evolving Anomalies
Certain anomalies may not be evident initially but can develop or worsen over time. Regular USG evaluations help monitor these, such as:
Hydrocephalus : Progressive dilation of cerebral ventricles may evolve into severe hydrocephalus.
*Congenital Heart Defects : Subtle anomalies in the first trimester may become more apparent during mid-trimester anomaly scans.
Renal Abnormalities :
Pelvicalyceal dilatation (pyelectasis) can evolve into hydronephrosis.
Polycystic kidney disease or multicystic dysplastic kidneys may develop features as gestation progresses.
Gastrointestinal tract abnormalities :like Duodenal atresia , bowel obstruction, atresia, dilatation
Diaphragmatic Hernia : Initially detected as abnormal abdominal organ positions, these may evolve to cause pulmonary hypoplasia.
*Amniotic Band Syndrome : Evolving deformities as the fetus grows, leading to limb or facial abnormalities.
Some anomalies are part of syndromes that evolve:
Down Syndrome : Initial findings like NT thickening may be accompanied by cardiac anomalies or duodenal atresia later.
Skeletal Dysplasias : Subtle findings like short limbs may progress to severe deformities.
Neurodevelopmental Issues : Corpus callosum agenesis or holoprosencephaly features may only fully manifest later in gestation.
