Fetal thoracic masses may cause hydrops and intrauterine death or pulmonary hypoplasia and neonatal ventilatory failure. We present a male fetus with two cystic masses which were detected at the 26º week of gestation. The huge unilocular right thoracic cystic mass measured 6 x 6 cm and caused a severe displacement of both lungs and the mediastinum. The abdominal cystic mass in the right flank was 4 x 4 cm. in size and had no communication with the former. Other associated anomalies were ruled out through a fetal MRI. Weekly sonographic follow-up until term did not show hydrops fetalis. Threfore a multidisciplinary perinatal reception was arranged at term, with a cesarean section, to immediately solve the expected neonatal hypoxia. The thoracic cyst was decompressed under US guidance with a 10 French trocar, and 200cc of fluid were evacuated before both lungs could expand. After 48 hours of ventilatory support, the thoracic intestinal duplication was resected through videothoracoscopy using 3 mm instruments. After an uneventful recovery, the abdominal jejunal cystic duplication, which had then expanded up to 8 x 8 cms., was also resected, through a mini-invasive laparoscopically assisted procedure at 18 days of age. The baby was discharged home with full breast feeding at 24 days of age.
