“…This case is of particular interest, because we had the opportunity to perform serial sonograms from an early stage in pregnancy. The lung cyst appeared very large in proportion to the fetal size at the first examination and the ultrasound features were suggestive of type I cystic adenomatoid malformation or bronchopulmonary sequestration 17,18. Both cystic lesions are thought to arise in early development, the former from failure of the pulmonary mesenchyme to induce normal bronchoalveolar differentiation and the latter from an aberrant outpouching of the developing foregut 19 .…”

“…Usually, these congenital lung malformations have a systemic arterial blood supply that can be seen on color flow imaging during the second half of pregnancy 17 . When the lesion regresses, which is not uncommon 17,18 , this anomalous blood supply is likely to disappear prior to or simultaneously with the disappearance of the lesion. This could explain why abnormal blood flow was not detected around the lesion.…”

An unusual case of chest cyst diagnosed at the end of the first trimester in a dizygotic twin pregnancy and managed conservatively is reported. Between 11 and 14 weeks of gestation, ultrasound revealed a relatively large echopoor lung cyst occupying the left side of the chest, displacing the mediastinum and the heart. This was associated with increased nuchal translucency thickness and generalized skin edema. Subsequent sonograms showed complete resolution of the cyst together with the skin edema. The fetuses were delivered at term and had an uncomplicated postnatal outcome. This case emphasizes the role of reduced venous return as a cause of early fetal hydrops. Diagnosis and follow-up of a congenital lung cyst from the end of the first trimester should enable early intervention to be made.

Objective We aimed to evaluate the contribution of prenatal magnetic resonance (MR) imaging to ultrasound (US) in the diagnosis of congenital thoracic abnormalities. Materials and MethodsThirty-three out of 984 pregnant women, with fetal thoracic anomalies detected at US and subsequently underwent fetal MR imaging were analyzed retrospectively. In the present methodological study, prenatal MR imaging and US findings are compared with postnatal imaging, autopsy, surgical pathologic examination, physical examination or clinical follow-up. Diagnostic sensitivities were calculated for US, MR imaging and combinations of both methods by comparing US and MR results with postnatal definite diagnoses. Results The sensitivities of US and MR imaging in detecting thoracic anomalies were 53.3% and 66.7%, respectively. Both US and MRI findings were consistent in prenatal imaging in a total 27 (82%) of cases. Both US and MR imaging made correct diagnosis in 48% of cases. MR imaging confirmed the suspected US diagnosis in 3%. Prenatal MR imaging positively contributed to US with revealing additional findings such as pulmonary hypoplasia and mediastinal shift in 30% cases. Main contribution (90%) of MR imaging to US was in congenital diaphragmatic hernia (CDH) cases. In all cases with CDH, MRI showed reduction in T2 signal consistent with pulmonary hypoplasia. MR imaging completely altered the diagnosis in 9% of cases. Total contribution rate of prenatal MR imaging to US was 42%. Sixty-seven percent of prenatally detected congenital cystic adenomatoid malformation (CCAM) and congenital lobar fluid overload (CLFO) cases exhibited spontaneous resolution before birth. Conclusion MR imaging as a complementary to US can be used successfully in the prenatal diagnosis of congenital thoracic pathologies. It can provide additional findings, confirm the suspected diagnosis or completely alter the prenatal US diagnosis. The most additional contribution of MRI to US was provided in cases of CDH.

Gereç ve Yöntemler Prenatal dönemde ultrason (US) de fetal torasik anomaliler tespit edilen ve ardından fetal MRG yapılan 984 gebenin 33'ü retrospektif olarak analiz edildi. Metadolojik çalışmada, prenatal MR görüntüleme ve US bulguları doğum sonrası görüntüleme, otopsi, cerrahi patolojik inceleme, fizik muayene veya klinik takip ile karşılaştırıldı. US, MRG ve her iki yöntemin kombinasyonları için tanısal duyarlılıklar, US ve MR sonuçları, doğum sonrası kesin tanılarla karşılaştırılarak hesaplandı. Bulgular US ve MRG'nin torasik anomalileri saptamadaki duyarlılıkları sırasıyla % 53.3 ve % 66.7 bulundu. Prenatal görüntülemede olguların %82'sinde hem MR hem de US bulguları birbiriyle uyumluydu.

1. Ultrasound evaluation of chest masses is useful in diagnosing of the type and the extent of the lesion, recognition of secondary alterations and exclusion of additional malformations. 2. Termination of pregnancy should be recommended in cases of hydrops that develops early in gestation, bilateral lesions with expected unfavourable outcome or life-threatening additional malformations. 3. Mediastinal shift does not seem to predict a poor perinatal outcome. 4. Spontaneous decrease of the size of the lesion is associated with a favourable outcome.
