Peritoneal calcification in a neonate with imperforate hymen

Area of Science:

• Neonatal imaging
• Pediatric radiology
• Fetal medicine

Background:

• Vaginography is a diagnostic imaging technique used to evaluate the female reproductive tract.
• Genital tract obstruction can occur in neonates, potentially leading to complications.

Observation:

• Contrast medium administered for vaginography in a premature neonate unintentionally entered the peritoneal cavity.
• Calcification was observed in the peritoneal cavity, suspected to be accumulated genital tract secretions.

Findings:

• The calcification was likely due to secretions accumulating above an imperforate hymen.
• Prenatal ultrasonography had previously identified fetal ascites, suggesting potential genital tract obstruction.

Implications:

• This case highlights a potential complication of vaginography in neonates.
• Prenatal diagnosis of fetal ascites may indicate the need for further investigation of genital tract obstruction.
• Early identification and management of genital tract obstruction are crucial for neonatal health.
