Recurrent Fetal Hydrops due to Mucopolysaccharidoses Type VII

Hydrops fetalis is associated with a wide range of abnormalities. In about 20% of cases of non-immune fetal hydrops, no cause is found despite investigations including routine post-mortem examination and enzyme studies may be indicated to detect an underlying metabolic storage disease. Fetal hydrops due to mucopolysaccharidosis type VII is very rare and a prenatal diagnosis is not usually made. We report a case of mucopolysaccharidosis type VII presenting as recurrent fetal hydrops and review the clinico-pathological features of this disorder.
