ABSTRACT

Introduction: Recurrent non-immune fetal hydrops (NIH) has been reported in the literature but is a rare entity, with fewer than 6 reported cases so far. It has been postulated to be related to a recessive gene.

Clinical Picture: We report a case of recurrent fetal hydrops in a multigravida with no medical history of note. She presented in her current pregnancy with a significant history of having 4 (out of 7) previous pregnancies affected by hydrops.

Treatment: All the affected pregnancies resulted in mid-trimester pregnancy termination (MTPT) following diagnosis in the second trimester. Previous investigations for hydrops did not yield any obvious cause.

Outcome: Her most recent pregnancy was unaffected. We discuss the possible differential diagnoses and the likelihood of autosomal recessive metabolic diseases being the aetiological factor.

Conclusion: Rare causes of fetal hydrops need to be excluded in cases of recurrent non-immune hydrops with no obvious aetiology following routine investigations.


The incidence of non-immune hydrops (NIH) has been reported to be 1/10001 and is associated with high perinatal morbidity and mortality at all gestational ages with an overall perinatal mortality rate (PNMR) of 86.6%. If the diagnosis is made before 24 weeks’ gestation, the PNMR is 95%, with 30% having an abnormal karyotype.
