  • AbstractHyperreactio luteinalis (HL) is characterised by ovarian cystic enlargement that is associated with high levels of human chorionic gonadotropin (hCG). Here the possible effects of abnormally high hCG levels on foetal development are demonstrated.We report a 28-year-old patient who was referred for evaluation of bilateral maternal ovarian enlargement in the second trimester. Abnormally elevated hCG (887,514 IU/L) was found with ultrasound examination identifying various foetal malformations. The karyotype was normal. Spontaneous abortion occurred at 20 weeks. Autopsy showed testicular hypertrophy with marked Leydig cell hyperplasia. The HL resolved with normalisation of the hCG levels following delivery.HL is a rare finding in normal pregnancies; the potential effects of abnormally elevated hCG on the foetus are discussed.
