Diagnosis of hydatidiform mole with and without coexistent fetus by nonstored image echography

One hundred ten patients suspected of having hydatidiform mole or partial mole were examined during a 21/2-year period, utilizing nonstored image echography. All echograms were performed and interpreted by an obstetrician-gynecologist. Hydatidiform mole was confirmed in 23 patients, 4 of whom presented with a coexistent fetus and 3 with blighted ovum. No false diagnoses of hydatidiform mole were made. Reasons for the superiority of a nonstored image technique are discussed, particularly with regard to elimination of primary and secondary problems inherent in echographic diagnosis.
