Foetal and neonatal splenic cyst-like lesions. US follow-up of seven cases.

Seven cases of small, asymptomatic splenic cyst-like lesions (CLL) diagnosed in foetuses and neonates are reported. None of these CLL was operated on; three completely disappeared. Such a complete regression has never been described before. A more conservative app approach to such lesions is suggested in order to prevent the possible complications of inappropriate interventional therapy.
