Prenatal pleural effusion associated with congenital pulmonary lymphangiectasia

A pleural effusion associated with congenital pulmonary lymphangiectasia was detected in a fetus in utero but was absent at the time of delivery. The pleural effusion was unilateral although the disease involved both lungs. In this case there was an association between polyhydramnios and congenital pulmonary lymphangiectasia.     

Rapid fetal karyotype from cystic hygroma and pleural effusions

Fluid from pleural effusion (n=2) and cystic hygroma (n=7) was obtained from eight fetuses, between 13 and 32 weeks of pregnancy at the time when a conventional prenatal diagnosis procedure was carried out. As these fluids contain lymphocytes, they were processed like peripheral blood. A karyotype was obtained in 4 days in both cases of pleural effusion and in four out of seven samples of cystic hygroma. An abnormal karyotype was detected in three of the four samples of cystic hygroma: two trisomies 21 and a monosomy X. Different parameters were evaluated in order to predict the feasibility of obtaining a cytogenetic diagnosis. Our data showed that if the amount of fluid obtained was ⩾4 ml and the initial lymphocyte count (ILC) was >0.2 × 10⁶ cells/ml, a cytogenetic diagnosis was possible from an initial concentration of cultured lymphocytes )ICCL) of >0.06 × 10⁶ cells/ml.     

Fetal pleural effusion

Fetal pleural effusion, a nonspecific accumulation of fluid in the pleural space, is an uncommon anomaly which can be associated with aneuploidy and a range of other structural malformations or genetic syndromes. Spontaneous resolution is not rare and confers a good prognosis. Perinatal outcome is better for those fetuses without hydrops than those presenting with hydrops. A detailed review of the literature indicates that, for fetuses with persistent effusions, in utero intervention (repeated thoracocentesis, intrauterine shunting and pleurodesis) may improve the chances of survival.

Congenital chylothorax-prenatal ultrasonic diagnosis and successful post partum management

The prenatal diagnosis by ultrasound of congenital chylothorax is described allowing early intervention immediately after delivery. Unilateral fluid collection in the right lung with marked displacement of the heart to the left were the most prominent sonographic signs. Post partum thoracocentesis and chylus fluid drainage served as a life saving procedure.     

Duchenne muscular dystrophy associated with fetal pleural effusion and polyhydramnios

A case of fetal pleural effusion in a fetus affected with Duchenne muscular dystrophy (DMD) is reported. This case is discussed in the context of the previous observation of frequent stillbirths among male fetuses in DMD families.
