Methods A retrospective study was on prenatal sonographic findings of 10 cases with ACC malformation and their abnormalities in central nervous system (CNS) or extra-CNS.Results The special sonographic findings established the diagnosis of ACC malformation in all 10 cases,with 7cases diagnosed absence agenesis. Among all patients with ACC,6 cases were accompanied with abnormalities in extra-CNS,8 in CNS and 5 in both. Conclusions Prenatal ultrasonography plays a vital role in accurate diagnosis on fetal ACC. Attentions should be paid to the indirect encephalic features and complicated abnormalities so as to make accurate and prompt diagnosis.
