Neonatal abdominal cystic masses: spontaneous regression demonstrated with ultrasound
1Department of Radiology, Semmelweis Medical University, Budapest, Hungary.
Insights
Conservative management with ultrasound follow-up is a viable option for uncomplicated abdominal cysts in infants, including multicystic dysplastic kidneys and ovarian cysts. This approach avoids surgery in many cases.
Area of Science:
- Pediatric imaging
- Neonatal surgery
Background:
- Abdominal cysts are a common finding in neonates.
- Diagnosis is often made via ultrasound.
- Management strategies range from observation to surgical intervention.
Purpose of the Study:
- To evaluate the efficacy of conservative management for abdominal cysts in infants.
- To determine if serial ultrasound is sufficient for monitoring cyst resolution.
Main Methods:
- Retrospective review of 14 infant cases diagnosed with abdominal cysts via ultrasound.
- Specific diagnoses included multicystic dysplastic kidneys, ovarian cysts, and bowel duplication.
- Follow-up included serial ultrasound examinations for 6 patients.
Main Results:
- Ultrasound identified 9 cases of multicystic dysplastic kidneys, 4 ovarian cysts, and 1 bowel duplication.
- In 6 followed patients, 2 multicystic dysplastic kidneys showed significant reduction.
- One ovarian cyst completely resolved during the observation period.
Conclusions:
- Conservative management with serial sonographic reevaluation is a safe and effective alternative to surgery for uncomplicated neonatal abdominal cysts.
- This approach can lead to spontaneous resolution or significant reduction in cyst size, avoiding invasive procedures.
Abstract:
Abdominal cyst was diagnosed in 14 babies by ultrasound examination (9 multicystic dysplastic kidneys, 4 ovarian cysts, 1 bowel duplication). The cysts were followed in 6 patients by ultrasound and marked reduction of multicystic dysplastic kidneys was observed in 2 patients, and 1 ovarian cyst fully disappeared. Their experience in agreement with the literature data suggest that conservative management with sonographic reevaluation is an acceptable alternative to surgical therapy in uncomplicated cases.
