Prenatally-detected giant lymphatic malformation

Area of Science:

• Pediatric Surgery
• Fetal Medicine
• Vascular Anomalies

Background:

• Giant lymphatic malformations (GLMs) are rare congenital vascular anomalies that can present significant diagnostic and management challenges, particularly when large or involving critical anatomical structures.
• Prenatal diagnosis of fetal anomalies allows for timely planning of postnatal management and can improve outcomes.
• Lymphatic malformations, a type of vascular anomaly, require specialized surgical approaches due to their infiltrative nature.

Observation:

• A case of a giant lymphatic malformation involving the chest and abdominal wall was diagnosed in the third trimester of pregnancy.
• The malformation presented a substantial mass, raising concerns for fetal well-being and potential delivery complications.

Findings:

• The giant lymphatic malformation was successfully treated with a single-stage surgical excision.
• Postoperative recovery was uncomplicated, demonstrating good functional restoration and satisfactory cosmetic results.

Implications:

• This case highlights the feasibility of single-stage excision for large congenital lymphatic malformations diagnosed prenatally.
• Effective surgical management can lead to excellent functional and aesthetic outcomes, improving the quality of life for affected infants.
• Multidisciplinary prenatal counseling and surgical planning are crucial for managing complex fetal vascular anomalies.
