Cytomegalic inclusion disease: intrauterine sonographic diagnosis using findings involving the brain

Two second-trimester cases and one third-trimester case of intrauterine cytomegalic inclusion disease (CID) are presented, each having a different intracranial sonographic presentation. The findings are correlated with radiographic studies and the known pathophysiology. Sonographic evidence of intrauterine cerebral necrosis or calcification should alert one to the possibility of CID, particularly if other signs of in utero infection are present. A pattern of bilateral periventricular calcifications, which may be preceded by hypoechoic periventricular ringlike zones, seems to be specific for intrauterine CID. However, CID also may result in widespread cerebral destruction. If the sonographic study produces an uncertain diagnosis, sonography can still aid in the prenatal diagnosis of CID by guiding percutaneous umbilical cord blood sampling for serology or by directing amniocentesis for cytomegalovirus culture. The ability of sonography to demonstrate specific characteristics of CID in utero enables prenatal diagnosis of this disease.
