Area of Science:

  • Genetics
  • Medical Imaging
  • Prenatal Diagnosis

Background:

  • Trisomy 9 is a rare chromosomal abnormality.
  • Accurate prenatal diagnosis is crucial for management and counseling.

Observation:

  • Two cases of trisomy 9 were identified.
  • Prenatal sonography revealed characteristic abnormalities.

Findings:

  • Sonographic findings included structural heart defects, limb, renal, and facial anomalies, and intrauterine growth retardation.
  • Cytogenetic and autopsy findings confirmed trisomy 9.

Implications:

  • Early identification of trisomy 9 through prenatal ultrasound can guide genetic evaluation.
  • Understanding these sonographic markers aids in diagnosing this rare condition.
