Neonatal abdominal cystic masses: spontaneous regression demonstrated with ultrasound.

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.
