Echogenic lung mass, in-utero fetal demise
Laura Hurtado, MD,
Buenos Aires, Argentina
This 23-year-old patient, G2P1, had a routine examination at 16 weeks and 5 days of pregnancy (according to LMP), with the following findings:
-
Intrathoracic mass of increased echogenicity containing small cysts,
-
Displacement of the heart (to the right thoracic wall), and
-
Diaphragmatic inversion towards the abdomen
-
Biometry consistent with LMP.

A reexamination at 22 w and 6 days demonstrated a biparietal diameter of 62 mm (24 w) femoral length 35 mm (20 w). There was hydrops and edema and short limbs. The mass was still present and displaced the heart.


A further examination at 25 w demonstrated a biparietal diameter of 66 mm (26 w) and femoral length of 39 mm (21 w and two days). The hydrops, edema and polyhydramnios increased.

Intrauterine fetal demise occurred at 28 w and 6 days....

Parents didn"t authorized an autopsy, so the nature of the lung mass is unknown but consistent with a Congenital lobar adenomatosis, type III
