Background The purpose of this study is to describe the monographic features and outcome of fetuses with isolated hyperechogenic foci in the thalamic region. Method A detailed monographic survey was performed in 46244 consecutive pregnancies. Both low and high‐risk pregnancies were included. Transvaginal examinations were performed at 14–16 weeks' gestation, while transabdominal examinations were performed after 18 weeks' gestation. Results Isolated hyperechogenic foci in the thalamic region were observed in 7 fetuses. All cases were diagnosed at 14–16 weeks' gestation. Six fetuses had one hyperechogenic focus, and one fetus had two foci. The size of these foci ranged from 2 to 4 mm. A serologic work‐up was negative in all these fetuses and their karyotype was normal. The hyperechogenic foci disappeared in mid‐pregnancy in all cases, and fetuses were normal at delivery and on follow‐up up to the age of 9 years. Conclusion Isolated hyperechogenic foci in the thalamic region in the early pregnancy have probably a benign nature.
