Abstract
OBJECTIVE The objective of this study is to assess the effectiveness and safety of intrafetal vascular laser ablation (VLA) for fetuses with bronchopulmonary sequestration (BPS) with hydrops. METHODS First, we present 3 cases of fetuses with BPS and hydrops treated by VLA. Second, we aimed to conduct a narrative review to identify all reported cases of fetuses with BPS treated by intrafetal VLA. RESULTS The review of the literature identified 41 fetuses treated by VLA for BPS with hydrops. The median gestational age of the VLA was 27+0 weeks' gestation [25+0-31+0] with an associated procedure at the same time in 43% of the cases (pleuroamniotic shunt, thoracentesis, and amniodrainage). A second procedure was required in 25% of cases for residual flow in the feeding vessel. No stillbirth or neonatal death was reported. The complications reported were a fetal thoracic hematoma complicated by fetal anemia and 4 preterm deliveries with a rate of 9%. CONCLUSION VLA of the feeding vessel can be an effective treatment but is not without complications. In cases demonstrating cardiac output failure, intrafetal VLA should be considered as a treatment for BPS.

Abstract
Purpose: Fetal lung masses complicate approximately 1 in 2000 live births. Our aim was to determine whether obstetric and neonatal outcomes differ by final fetal lung mass histology.Materials and methods: A review of all pregnancies complicated by a prenatally diagnosed fetal lung mass between 2009 and 2017 at a single academic center was conducted. All cases included in the final analysis underwent surgical resection and histology diagnosis was determined by a trained pathologist. Clinical data were obtained from review of stored electronic medical records which contained linked maternal and neonatal records. Imaging records included both prenatal ultrasound and magnetic resonance imaging. Fisher's exact test was used for categorical variables and the Kruskal-Wallis test was used for continuous variables. The level of significance was p<.05.Results: Of 61 pregnancies complicated by fetal lung mass during the study period, 45 cases underwent both prenatal care and postnatal resection. Final histology revealed 10 cases of congenital pulmonary airway malformation (CPAM) type 1, nine cases of CPAM type 2, and 16 cases of bronchopulmonary sequestration. There was no difference in initial, maximal, or final CPAM volume ratio between groups, with median final CPAM volume ratio of 0.6 for CPAM type 1, 0.7 for CPAM type 2, and 0.3 for bronchopulmonary sequestration (p = .12). There were no differences in any of the maternal or obstetric outcomes including gestational age at delivery and mode of delivery between the groups. The primary outcome of neonatal respiratory distress was not statistically different between groups (p = .66). Median neonatal length of stay following delivery ranged from 3 to 4 days, and time to postnatal resection was similar as well, with a median of 126 days for CPAM type 1, 122 days for CPAM type 2, and 132 days for bronchopulmonary sequestration (p = .76).Conclusions: In our cohort, there was no significant association between histologic lung mass subtypes and any obstetric or neonatal morbidity including respiratory distress.

Abstract
Neuroblastoma is the most common pediatric extracranial solid tumor derived from primitive neural crest cells of the sympathetic nervous system. Although one-fifths of all neuroblastomas occurs within the thorax, thoracic neuroblastomas detected in fetus have been rarely reported. We report a case of fetal thoracic neuroblastoma with massive pleural effusion detected with prenatal ultrasonography. A 34-year-old Korean second-gravida was referred to our hospital at 30 weeks of gestation for evaluation, after the right lung mass found in the fetus. Approximately 3 cm, well-defined, hyperechoic mass was found in the right thorax with right pleural effusion, with the initial suspicion of teratoma. However, as mass continued to grow with deteriorating pleural effusion and fetal hydrops, the mass was considered malignant after 3 weeks. After a cesarean delivery, an approximately 4 cm mass with peripheral calcification and hemothorax was found on neonatal ultrasonography. Neuroblastoma was diagnosed on excision biopsy.

Abstract
Congenital cystic adenomatoid malformation is a rare pulmonary lesion that can be diagnosed prenatally by ultrasonography. This hamartomatous pulmonary mass is typically unilateral and usually involves one lobe or segment of the lung. Hamartomas are rare tumors of variable physical appearance, whose sonographic appearance is usually that of a predominantly cystic or solid mass. Typically slow growing, it is not uncommon for focal calcifications to develop. On rare occasion, hamartomas may be bilateral or involve the entire lung. Pulmonary sequestrations probably represent bronchopulmonary foregut abnormalities. Extralobar lesions are the least common overall, but are the most common form found in neonates and nearly the only form that has been detected prenatally. Sequestrations occur most commonly on the left (90%) in the posterior and basal segments. Subdiaphragmatic lesions (which account for 2.5% of bronchopulmonary foregut malformations) have been observed prenatally associated with other anomalies, including foregut abnormalities and congenital diaphragmatic hernia in 58% of cases. This form of sequestration has rarely been diagnosed prenatally. The following case report illustrates cystic adenomatoid malformation in extralobar pulmonary sequestration.

Abstract
PURPOSE To describe the prenatal findings, treatments and outcomes of fetuses with pulmonary sequestrations (PS), which were retrospectively studied. METHODS From May 2010 to January 2013, 292 women were referred to the Guangdong Women and Children Hospital, Guangzhou because obstetric ultrasound had demonstrated fetal lung lesions. In 68 fetuses, the echogenic lung masses were pulmonary sequestrations deriving arterial blood supply from clearly identifiable systemic arteries rather than the pulmonary artery. We examined records of the 68 fetuses and measured the lesions and congenital cystic adenomatoid malformation volume ratio (CVR), provided prenatal counseling and treatment, documented the CVR, location of lesion, gestational age at diagnosis, need for fetal intervention, perinatal clinical course (including the development of hydrops, effusions, and neonatal respiratory distress), gestational age at delivery, postnatal ultrasound and CT, operation treatment, survival and pathology. RESULTS There were 68 PS in our study. All of 56 cases with CVR ≤ 1.6, survived without prenatal hydrops or postnatal respiratory symptoms. In 12 cases with CVR >1.6, 7 cases (58.3 %, 7/12) had hydrops, 10 cases (83.3 %, 10/12) survived, 2 cases (16.7 %, 2/12) of induced abortion, 8 cases (66 %, 8/12) were postnatal symptomatic. There was statistical significant difference in the incidence rate of hydrops and postnatal respiratory symptoms between the PS with CVR ≤ 1.6 and that with CVR >1.6. 66 cases postnatal survived, two cases of induced abortion. 64 cases had no prenatal treatment, two cases underwent thoracoamniotic shunt. The mean gestational age at birth was 38 weeks (range 34-40 weeks). 21 asymptomatic cases had no surgery. 45 cases (8 symptomatic and 37 asymptomatic) underwent surgical resections, 43 cases without postoperative complications, two cases of postoperative pneumothorax, no wound infection. Postoperative follow-up showed good growth in all surgery cases. CONCLUSION PS specific absence of hydrop was a congenital disorder with an excellent prognosis. CVR >1.6 was associated with fetal hydrops and postnatal symptoms. However, absolute CVR value cannot be used to select fetuses for fetal treatment before the development of hydrops. Surgery of PS in neonates or infants presented a good outcome.

Abstract
Congenital thoracic malformations (CTMs) are a heterogeneous group of rare disorders that may involve the airways or lung parenchyma. The authors have focused on the condition that causes the most controversy, namely, congenital cystic adenomatoid malformation (CCAM). The reported incidence is 3.5 and 0.94 per 10,000 live births for CTMs and CCAMs respectively. Ultrasound is the antenatal imaging modality of choice for screening for CCAMs whilst magnetic resonance imaging is complimentary for morphological and volumetric evaluation of the foetal lung. Most CCAMs are detected antenatally with only a small proportion presenting postnatally. Only a few CCAMs cause foetal problems, with foetal hydrops being the best predictor of death. Although many CCAMs regress during pregnancy, most remain detectable postnatally by CT scans. Surgical excision of symptomatic lesions is relatively straightforward, but management of asymptomatic lesions is controversial. Some surgeons adopt a "wait and see" approach operating only on those patients who develop symptoms, but others operate on asymptomatic patients usually within the first year of life. Due to the potential of malignant transformation, children should have long term follow up. There is an urgent need to delineate the natural history of antenatally detected CCAMs to guide future management.

Abstract
Intralobar pulmonary sequestration is characterized by the presence of nonfunctional parenchymal lung tissue, receiving systemic arterial blood supply. It lacks normal communication with tracheobronchial tree. Failure to diagnose and treat this condition can lead to recurrent pneumonia and fatal hemoptysis. The aim of this case report is to increase awareness about the condition and to review criteria of its definitive diagnosis and subsequent treatment.

Abstract
Hybrid lesions are part of a spectrum of rare pulmonary diseases that are characterized as having elements of both congenital pulmonary airway malformation and bronchopulmonary sequestration. Fetal thoracic masses arise from alterations during lung development that are separated by timing of the inciting event and are often associated with an underlying degree of bronchial atresia. There are a handful of documented reports of sequestrations occurring in siblings, but no known reports of prenatally diagnosed lesions occurring in families. We present a case of 2 siblings diagnosed prenatally with fetal thoracic lesions who underwent postnatal resection revealing hybrid lesions on pathologic examination. Newer radiologic techniques have increased our ability to detect these masses prenatally, as well as follow them throughout pregnancy to determine their natural history. Ongoing laboratory investigation into the etiology of congenital lung lesions has brought forth more questions and suggested a familial component at a cellular level that has not yet been fully discovered. We reviewed the current literature of factors contributing to the development of congenital lung lesions and suggest that there is a familial link in certain patient populations where screening may be indicated.

Abstract
PURPOSE The aim of this study was to assess the computed tomography (CT) features of intrapulmonary congenital cystic diseases in adults and to correlate the imaging features with the pathological findings, with emphasis on the oncogenic potential of the lesions. MATERIALS AND METHODS We retrospectively reviewed the CT scans in three institutions from August 1996 to December 2008, of nine patients (six men, three women; mean age 48.6 years; range 26-75 years) who had histological diagnosis of pulmonary cystic disease after surgery. Six patients had a diagnosis of intrapulmonary bronchogenic cyst (IBC), and three had a type-I cystic adenomatoid malformation (CAM). In one case, intralobar sequestration (ILS) was associated with type-I CAM. RESULTS Three patients were symptomatic and six were asymptomatic. On CT scans, IBCs showed homogeneous fluid attenuation (n=2), air-fluid level (n=2), air attenuation (n=1) or soft-tissue attenuation (n=1). The surrounding lung tissue showed areas of band-like linear attenuation in three IBCs, atelectasia in two and mucocele-like areas in one. On CT, type-I CAM appeared as a unilocular cystic lesion with air-fluid level (n=1) or air content (n=1). Both cases had thin walls surrounded by normal lung parenchyma. ILS appeared as a fluid-filled cyst with afferent and efferent vessels. Of the six IBCs, one occurred in the upper right lobe, two in the middle lobe and three in the lower right lobe. Of the three type-I CAMs, one was in the upper left lobe and one in the middle lobe. The type-I CAM associated with ILS was located in the left lower lobe. CONCLUSIONS The similar CT patterns preclude differentiation between IBC and type-I CAM. Surgical resection of all intrapulmonary cystic lesions detected in adults is mandatory because type-I CAM is a precursor of mucinous bronchioloalveolar carcinoma.

Abstract
Cysts within the lung are one of the more common pulmonary pathological findings seen in an active pediatric surgical pathology service. Of both developmental and acquired origin, they may present as respiratory distress in infants or may be asymptomatic lesions incidentally discovered by images studies of the thoracic for "non-pulmonary" reasons. The most frequently seen developmental cysts of the lung are those of Congenital Pulmonary Airway Malformations, types 1, 2 & 4. Other congenital cystic lesions include bronchogenic cysts (usually in older patients) and some of the enteric duplication lesions that contain cysts. Acquired cystic lung lesions include acute and persistent pulmonary interstitial emphysema, postinfarction peripheral cysts, postinfectious pulmonary cysts, and the cystic form of pleuropulmonary blastoma.

Abstract
OBJECTIVE To describe the antenatal findings and outcome of fetuses with echogenic lung lesions. METHODS This was a retrospective study of the prenatal sonographic features, antenatal management and outcome of 193 fetuses with an echogenic lung lesion diagnosed at 18-35 weeks of gestation. There were nine cases of congenital high airway obstruction syndrome (CHAOS), 170 cases of cystic adenomatoid malformation (CAM) and 14 cases of pulmonary sequestration (PS). A literature search was also carried out to compare our data with those of previous series. RESULTS The prognosis in our series of fetuses with CHAOS was invariably poor, but the literature describes a handful of survivors after delivery by Cesarean section and ex-utero intrapartum therapy (EXIT). Of the cases in our series with PS and no pleural effusions, more than 95% survived; in half of these cases the lesion resolved antenatally and in the other half sequestrectomy was carried out postnatally. In cases with PS and pleural effusions, successful treatment was provided by the placement of thoracoamniotic shunts or occlusion of the feeding blood vessel by ultrasound-guided laser coagulation or injection of sclerosants. In cases with CAM and no hydrops, there was more than 95% survival and in up to half of the cases there was sonographic evidence of spontaneous antenatal resolution of the hyperechogenic lesion, which was confirmed by postnatal imaging in about 60% of the cases. Of the cases with CAM with hydrops managed expectantly, more than 95% died before or after birth. Of the cases with macrocystic CAM with hydrops, two-thirds survived after placement of a thoracoamniotic shunt. In cases with microcystic CAM with hydrops, there is some evidence that open fetal surgery with lobectomy could improve survival but such treatment is highly invasive for the mother. CONCLUSIONS CHAOS is a severe abnormality, whereas CAM and PS are associated with a good prognosis. In a high proportion of fetuses with hyperechogenic lung lesion, there is spontaneous antenatal resolution and the underlying pathology may be transient bronchial obstruction.

Abstract
Pulmonary sequestration (PS) is a rare congenital malformation of the lower respiratory tract. The exact natural course of PS is not well understood and there are no well-established treatment guidelines for antenatally diagnosed PS. The aim of this study was to describe clinical outcomes in neonates with PS and to evaluate the efficacy of transumbilical arterial embolization (TUE). From 1998 to 2006, total 30 neonatal cases were included. Serial antenatal ultrasound in 26 cases found 6 (23%) regressed lesions, all of which were demonstrated on postnatal chest CT. Six (20%) cases were classified as mixed-type (combined cystic) lesions. Surgery was performed early (during initial hospitalization) in two cases and lately (after the neonatal period) in four cases. TUE was performed for 17 (57%) cases of intrapulmonary PS. Follow-up images obtained a median of 19 months (range, 4-51) after TUE demonstrated complete (9, 53%), partial (5, 29%), and no (3, 18%) regression. The regression rate was significantly higher in solid-type lesions (13/13, 100%) than in mixed-type (1/4, 25%) (P = 0.006). Complications included transient hypertension (two cases, 12%), post-embolization fever (two cases, 12%) and migration of a microcoil (one case, 6%), without long-term morbidities. Natural courses could be observed in 10 cases of extralobar PS and regression was observed in 2 cases (20%) during a median follow-up of 12 months (range, 6-45). A well-designed comparative study is warranted to evaluate the long-term efficacy and safety of TUE.

Abstract
Pulmonary vascular malformations have historically been diagnosed in a wide range of age groups, but the extensive use of prenatal imaging studies has resulted in the majority of lesions being diagnosed in utero. Among this group of lesions, bronchopulmonary sequestrations (BPS), hybrid lesions with both congenital cystic adenomatoid malformation (CCAM) and BPS, aberrant systemic vascular anastomoses, and pulmonary arteriovenous malformations (PAVM), are the most common. The biologic behavior of these lesions and the subsequent therapy is, in large part, determined by the age of the patient at diagnosis. In the fetus, large BPS or hybrid lesions can result in fetal hydrops and in utero fetal demise. In the perinatal period, pulmonary hypoplasia from the mass effect or air trapping within the cystic component of hybrid lesions can result in life-threatening respiratory distress. In the postnatal period, communication of the lesion with the aero-digestive system can result in recurrent pneumonia. Alternatively, increased pulmonary blood flow from the systemic arterial supply can result in hemorrhage, hemoptysis, or high output cardiac failure. In addition, there have been several reports of malignant degeneration. Finally, the broad spectrum encompassed by these lesions makes classification and subsequent communication of the lesions confusing and difficult. This paper will review the components of these lesions, their associated anomalies, the diagnosis and natural history, and finally, current concepts in the management of pulmonary vascular malformations.

Abstract
We report on the prenatal diagnosis of partial trisomy 1q and monosomy X in a fetus with a congenital lung lesion and hydrops. The finding of hydrops in a fetus with a small lung lesion, congenital cystic adenomatoid malformation (CCAM) volume to head circumference ratio (CVR) 0.78, prompted cytogenetic analysis of amniotic fluid, revealing an unbalanced translocation between chromosomes X and 1 [46,X,der(X)t(X;1)(p11.2;q25 or q31)]. The incidence of chromosomal abnormalities with CCAM lesions is estimated at 1.6%. This is the first reported case of prenatally diagnosed partial trisomy 1q and monosomy X presenting as a fetal lung lesion and hydrops.

Abstract
OBJECTIVE Evaluate the advantages of color Doppler and pulsed Doppler in the diagnosis and prognosis of fetal pulmonary malformations. MATERIALS AND METHOD This retrospective study of 24 fetuses explored pulmonary malformations using sonography. A classification into four groups was made based on the presence of cysts and the echogenicity of the lesion, then analysis of video recordings including Doppler with an interpretation chart: afferent vessel, color chart, spectrum shape (afferent vessel and within the malformation) to determine the contribution of Doppler within each group. RESULTS Four lesions were avascular: bronchogenic cysts (three cases), subphrenic sequestration (one case). The other lesions were vascularized and color Doppler determined the source of vascularization feeding the malformation: branches of the pulmonary artery in 13 cases (eight cases of cystic adenomatoid disease, two cases of atresia, and three airway obstacles) or the aorta in seven cases (pulmonary sequestrations) with pulmonary venous return, six cases (intralobular sequestrations), or systemic venous return, one case (extralobular sequestration). The pulsed Doppler recording in the malformation (six cases) completed the color Doppler examination by showing the different spectrum shapes according to the aortic or pulmonary source of flow. The color chart matched in three cases (normal pulmonary segmentation) and was heterogeneous in eight cases (parenchymatous dysplasia). Furthermore, perfusion intensity was correlated with lesion progression. CONCLUSION Color Doppler and pulsed Doppler provided a more precise diagnosis of these malformations and seems to contribute prognostic information.

Abstract
PURPOSE We describe our experience with fetuses diagnosed with life-threatening chest masses who were delivered by ex utero intrapartum treatment with placement on extracorporeal membrane oxygenation (EXIT-to-ECMO). METHODS The first fetus presented with a cystic mediastinal mass and enlarging echogenic lungs. Bronchoscopic evaluation during ex utero intrapartum treatment (EXIT) revealed complete airway obstruction secondary to a carinal bronchogenic cyst. The second fetus presented with a massive left congenital cystic adenomatoid malformation. The EXIT procedure was performed because of significant mediastinal shift, severe compression of the normal lung parenchyma, and signs of fetal distress. RESULTS In both cases, extracorporeal membrane oxygenation (ECMO) was initiated while on placental support. The fetuses were then delivered, and a definitive resection of their thoracic lesions was successfully performed. There were no major perioperative complications. Both children made expedient recoveries without significant cardiopulmonary sequelae. CONCLUSION To our knowledge, this is the first report describing the successful use of EXIT-to-ECMO as a bridge to definitive resection of large chest masses diagnosed in utero. EXIT-to-ECMO is a novel and effective management strategy for stabilizing patients with profound respiratory compromise secondary to congenital thoracic lesions.

Abstract
PURPOSE The prognosis for fetuses with large congenital cystic adenomatoid malformations (CCAMs) remains uncertain. This study examined the natural history of large fetal CCAMs managed expectantly at a major referral center. METHODS A 5-year retrospective review was conducted on fetuses diagnosed with a thoracic lesion (n = 59). Large CCAMs were identified on prenatal imaging and followed longitudinally. Perinatal outcomes were assessed. RESULTS Twelve (20.3%) fetuses had large CCAMs in the absence of other congenital anomalies. Peak CCAM size occurred at 25.3 +/- 3.6 weeks' gestation. Serial magnetic resonance volumetry demonstrated a trend toward decreasing CCAM mass volume relative to thoracic cavity volume over time. Overall, 6 patients, including 3 with signs of early hydrops, showed a marked regression of their lesions relative to estimated fetal weight. Five fetuses required an emergent intervention postnatally, including extracorporeal membrane oxygenation support (n = 1), cyst aspiration (n = 1), and lung resection (n = 5). Overall survival was 75%, with severe hydrops before 30 weeks seen in all 3 deaths. CONCLUSION Large fetal CCAMs tend to peak in size at 25 weeks' gestation and are characterized by in utero diminution relative to overall fetal growth. The prognosis for most fetuses with large CCAMs remains quite favorable under careful perinatal management.

Abstract
OBJECTIVES Despite the feasibility of detecting lung lesions by antenatal ultrasound, there are problems in correlating the prenatal diagnosis with the final histology and in predicting the outcome. In order to better describe these factors, we reviewed the outcome of fetuses that had been diagnosed with echogenic lung in a referral fetal medicine unit. METHODS We searched the database of a tertiary fetal medicine unit for all cases of fetal echogenic lung seen since 1994 and studied the maternal and neonatal records found. RESULTS There were 48 cases of echogenic lung diagnosed at a median gestational age of 21 (range, 19-29) weeks, including 43 (90%) cases of congenital cystic adenomatoid malformation (CCAM) and 5 (10%) of pulmonary sequestration (PS). The evolution of the fetal abnormality after diagnosis was: in 22 (45.8%) cases the lesion disappeared; in 17 (35.5%) cases the lesion remained stable and six (12.5%) cases became severe. Three (6%) women underwent termination of pregnancy. The lesions were equally distributed between the two sides of the thorax. Mediastinal shift was associated with a threefold increase in the possibility of clinical deterioration (17% vs. 5%), and the disappearance of the lesion was twice as likely to occur when the lesion was classified as microcystic as when it was macrocystic (67% vs. 36%). Features of hydrops were found in 9 (21%) fetuses and in six (13%) cases progressed and resulted in intrauterine or neonatal death. Sixty-four percent of cases with lesions that disappeared during the pregnancy had an abnormal computed tomography (CT) scan, and the prenatal diagnosis correlated with histology in 36% of these cases. Of the cases in which the lesions remained stable, 70.5% had an abnormal CT scan and the prenatal diagnosis correlated with the histology in 67% of the cases. CONCLUSIONS Prenatally diagnosed echogenic lung has a good prognosis in the absence of hydrops. The ability to correctly assess echogenic lung lesions and the need for surgery by prenatal ultrasound is limited.

Abstract
Congenital lung malformations are often discovered incidentally on routine prenatal sonography or postnatal imaging. Lesions such as congenital cystic adenomatoid malformations (CCAM), sequestrations, bronchogenic cysts and congenital lobar emphysema may be asymptomatic at birth or at the time of discovery later in life. Some authors advocate simple observation because of the lack of data on the incidence of long-term complications. However, there are very few described cases where CCAM and intralobar sequestration have remained asymptomatic throughout life; complications eventually develop in virtually all patients. The most common complication is pneumonia, which may respond poorly to medical treatment. Other complications include the development of malignancies (carcinomas and pleuropulmonary blastomas), pneumothorax and hemoptysis or hemothorax. Since lung resection will be required sooner or later for CCAM, intralobar sequestration and intrapulmonary bronchogenic cysts it is best not to wait for complications to occur. For patients diagnosed prenatally, we recommend surgery at 3 to 6 months of life at the latest, so that compensatory lung growth can occur. At this age the postoperative course is usually smooth and long-term follow-up has shown normal respiratory function. Mediastinal bronchogenic cysts also tend to become symptomatic and elective resection is recommended. On the other hand, asymptomatic congenital lobar emphysema may regress spontaneously and observation is warranted. The management of small noncommunicating extralobar sequestrations is more controversial; it is known that these lesions can remain asymptomatic throughout life but complications may develop and they are sometimes difficult to differentiate from neuroblastoma.

Abstract
BACKGROUND The majority of congenital cystic adenomatoid malformation (CCAM) lesions are diagnosed antenatally. A few cases however may not be recognised antenatally and present in infancy or later childhood with chest symptoms, including chest infection. OBJECTIVE To review the clinical and radiological spectrum of CCAM, comparing the antenatally with the postnatally diagnosed cases. MATERIALS AND METHODS Fifteen cases of antenatally and/or postnatally diagnosed and histopathologically proven CCAM were retrospectively identified over a period of 4 years. Clinical notes, chest radiograph and chest CT were reviewed in all cases. RESULTS Nine patients were diagnosed antenatally and six postnatally. All antenatally diagnosed patients were asymptomatic at birth, six remained asymptomatic until they had elective surgery and the remaining three developed symptoms before the age of 2 years. In the postnatally diagnosed group, one patient was symptomatic at birth and one patient presented at 16 years; the remaining four presented before the age of 2 years. Depending on the type of lesion, we recognised five radiographic patterns of CCAM. CCAM lesions were classified as CT Stocker type I in seven cases, type II in seven cases and type III in one case. CONCLUSIONS No significant difference was found between the two groups. Recognition of these lesions antenatally would benefit patients by avoiding delay in making the diagnosis, which can lead to serious complications. CT was successful in accurately diagnosing and grading CCAM lesions.

Abstract
Congenital pulmonary airway malformation, or congenital cystic adenomatoid malformation, is postulated to be a disorder of pulmonary airway morphogenesis and encompasses 5 different types with distinct levels or stages of tracheobronchial development. We present a unique case of type 2 congenital pulmonary airway malformation with a previously undocumented combination of multiple extrapulmonary anomalies, featuring ipsilateral multicystic renal dysgenesis, contralateral renal agenesis, and ovarian germ cell hypoplasia, diagnosed in a 19-week gestational age fetus by autopsy. Epithelial cells comprising the pulmonary lesions were positive for thyroid transcription factor-1, surfactant protein-B, and cytokeratin-7 but negative for cytokeratin-20 immunostainings, with the pattern seen in normal terminal bronchioles. Chromosomal analysis showed a normal female karyotype, despite a high estimated risk for Down syndrome suggested by the low maternal serum alpha-fetoprotein level.

Abstract
Congenital Pulmonary Airway Malformation (CPAM) and lung sequestration are often discovered on routine prenatal sonography. While some lesions may be large and cause serious complications in the fetus or newborn, many will be asymptomatic at birth. Some authors advocate simple observation because of the lack of data on the incidence of long-term complications. However, there are very few described cases where CPAM and intralobar sequestration (ILS) have remained asymptomatic throughout life; complications eventually develop in virtually all patients. The most common complication is pneumonia, which may respond poorly to medical treatment. Other complications include the development of malignancies (carcinomas and pleuropulmonary blastomas), pneumothorax and hemoptysis or hemothorax. Since lung resection will be required sooner or later for CPAM and ILS, it is best not to wait for complications to occur. We recommend surgery at 3 to 6 months of life at the latest, to allow compensatory lung growth to occur. At this age the postoperative course is usually smooth and long-term follow- up has shown normal respiratory function. The management of small non- communicating extralobar sequestrations is more controversial; it is known that these can remain asymptomatic throughout life but complications may develop and they are sometimes difficult to differentiate from neuroblastoma.

Abstract
The ability to identify and confidently diagnose a wide range of congenital fetal thoracic lesions has increased tremendously in the past 2 decades with the emergence of high-resolution sonography and ultrafast MRI sequences. Imaging studies constitute a vital component in the diagnosis of these lesions, whether in the fetal, neonatal or childhood periods. In addition to providing a road map for potential intervention, imaging techniques have provided important information about normal development, natural history, and prognosis. In the prenatal stage, these features aid in family counseling, pregnancy management, and the identification of a subgroup of patients who may benefit from fetal intervention. In the neonatal and childhood periods, imaging studies facilitate timely diagnosis and institution of appropriate therapeutic strategies.

Abstract
Pulmonary sequestration refers to the situation whereby a portion of lung tissue receives its blood supply from an anomalous systemic artery. Three main variants exist: intralobar, extralobar and communicating bronchopulmonary foregut malformations. Venous drainage is typically via a systemic vein, although drainage into the pulmonary veins is well documented. Pulmonary sequestrations are the second commonest congenital lung anomaly. Affected individuals often have other anomalies which are responsible for most of the mortality associated with sequestrations. Diagnosis requires a high index of suspicion particularly in any child with a chest x-ray suggesting the presence of a mass, those with recurrent chest infections and those with other anomalies seen with the pulmonary sequestration spectrum. Surgical excision is usually advised, although embolisation of the feeding vessel has a role in selected cases.

Abstract
PURPOSE The aim of this retrospective study was to compare changes in size and appearance of fetal lung masses detected on prenatal sonography with those on postnatal CT. PATIENTS AND METHODS Sixteen fetuses with echogenic lung masses had undergone serial sonography in utero as well as postnatal CT scanning. Changes in size of the masses were determined by comparing initial and follow-up sonograms. The appearance of the lesions on postnatal CT scans was classified as consolidation, cavity, ground-glass opacity, or atelectasis. All sonographic and CT findings were analyzed by 2 experienced radiologists who were unaware of previous imaging results. RESULTS The initial mean size of the fetal lung masses on prenatal sonography was 31 (anteroposterior dimension)x25(width)x36(craniocaudal length) mm. Follow-up serial sonography revealed complete regression of 10 masses, no change in 4, partial regression of 1, and increased size in 1. On postnatal chest CT, the mean mass size was 32x22x28 mm; 6 lesions showed no size change from that on the initial sonograms, 6 showed partial regression, and 4 showed an increase in size. Of the 10 cases with apparently complete regression on prenatal sonography, all showed positive findings on postnatal CT. CONCLUSIONS The discrepancy between prenatal sonographic and postnatal CT findings supports the assumption that regression of lung masses during serial prenatal sonographic follow-up does not always indicate their complete regression.

Abstract
Congenital cystic adenomatoid malformation of the lung can be detected with antenatal ultrasound as hyperechogenic areas in the fetal chest. Associated extrapulmonary malformations as well as chromosomal aberrations are described as very rare. We present a case report of a fetus in the 23rd week of gestation who showed in the course of a routine ultrasound screening a large number of malformations: holoprosencephaly, arrhinencephaly, cleft palate, CCAM type III of the right inferior pulmonary lobe, ventricular septal defect and bilateral clubfeet. Chromosome analysis confirmed the suspicion of trisomy 13. The present case shows how important it is-even with malformations that are rarely accompanied by associated anomalies and which have a very good prognosis-to carry out a directed diagnosis including a fetal karyotyping.

Abstract
Sessions papers from early modern Portsmouth survive from 1653 on and are nearly continuous for eighty-five years, that is, from 1696 to 1781. They include 356 cases of wife beating in addition to 7,658 other assaults; as such, the town's records allow for a comparison of the violent behavior of individual wife beaters both inside and outside of their marriages. These comparisons suggest that assaults on wives were more severe than assaults on strangers and acquaintances: not only were many wives assaulted on several occasions before lodging a complaint, the attacks themselves often resulted in greater injury, reflecting (1) a greater tendency to use potentially lethal weapons and (2) a differential in strength between most husbands and wives. The motives of individual wife beaters are less clear; what can be said with certainty is that wife beatings, like assaults in general, tended to rise whenever soldiers were demobilized and men were either unemployed or underemployed.

Abstract
The purposes of this study are to describe experience with the safety and long-term efficacy of transcatheter arterial embolization (TAE) of pulmonary sequestration in neonates and to introduce a new technique of embolization by an umbilical-artery route. TAE was performed in five neonates, via the femoral artery in one and the umbilical artery in four. Complete regression was achieved in four cases and partial regression (>90%) was obtained in one. TAE is a safe and effective alternative therapeutic modality for the treatment of pulmonary sequestration. The umbilical artery represents a preferable route for performing embolization in neonates.

Abstract
Congenital cystic adenomatoid malformation is a pulmonary developmental anomaly arising from an overgrowth of the terminal respiratory bronchioles. In the vast majority of cases, this mass is almost always unilateral and involves a single lobe of the lung. This anomaly has a slightly higher incidence in male than in female fetuses. Accurate prenatal sonographic diagnosis of a fetal lung mass is paramount to establishing an appropriate surgical and obstetrical management plan as well as ensuring the patient’s choice of therapeutic options.

Abstract
OBJECTIVE To review our experience with the use of sonography in evaluating potential candidates for in utero fetal therapy performed at The Center for Fetal Diagnosis and Treatment at The Children's Hospital of Philadelphia. METHODS This review article was designed to discuss open hysterotomy for the 4 fetal surgical procedures that have been performed at our institution. The procedures included surgical repair of myelomeningocele, resection of sacrococcygeal teratoma in fetuses with nonimmune hydrops, resection of an enlarging congenital cystic adenomatoid malformation that is not amenable to thoracoamniotic shunting, and tracheal clip occlusion for severe left congenital diaphragmatic hernia. RESULTS For each surgical procedure, the use of sonography in the prenatal diagnosis of the congenital anomaly was detailed, as were indications for surgery and surgical procedures, postoperative monitoring and finally delivery, postnatal treatment, and long-term follow-up. Three of the procedures have been reasonably successful with rather dramatic results in some cases such that these techniques are still being performed. The 1 exception was open hysterotomy for the tracheal clip procedure for congenital diaphragmatic hernia, which has been abandoned. CONCLUSIONS Fetal therapy is a rapidly evolving specialty, which is being practiced at several centers in this country. Sonography is an integral part of this specialty practice and has been used extensively in the diagnosis of some congenital anomalies that have debilitating or lethal consequences for the fetus. Technologic improvements in both sonography and magnetic resonance imaging have assisted tremendously in the many advances herein reported in the diagnosis and treatment of the above-described 4 congenital anomalies.

Abstract
Congenital masses of the lung are a spectrum of interrelated abnormalities that includes congenital lobar overinflation, bronchogenic cyst, congenital cystic adenomatoid malformation (CCAM) and sequestration. The prenatal and postnatal imaging features of these lesions are reviewed, emphasizing the importance of serial prenatal sonograms and postnatal imaging studies, including radiography and computed tomography. Masses that become inconspicuous, or disappear on serial prenatal sonograms are discussed, as well as the importance of postnatal imaging studies in the evaluation of these lesions. Finally, the management of congenital masses of the lung is reviewed, emphasizing the importance of imaging studies in the preoperative evaluation.

Abstract
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.

Abstract
BACKGROUND Sequestration with associated cystic adenomatoid malformation is rare. A study was undertaken to determine whether pulmonary sequestration associated with congenital cystic adenomatoid malformation has a more favourable natural history than that of sequestration without associated cystic adenomatoid malformation. METHODS An outline of the postnatal work up leading to the management of extralobar or intralobar pulmonary sequestration with congenital cystic adenomatoid malformation diagnosed antenatally as pulmonary malformation is presented and the indications for surgical intervention are discussed. RESULTS In five infants in whom an antenatal ultrasound scan had detected a congenital lung malformation at 18-19 weeks gestation a final diagnosis of extralobar or intralobar pulmonary sequestration with congenital cystic adenomatoid malformation was made postnatally. Postnatal ultrasound and computerised axial tomographic scans confirmed the diagnosis of sequestration by delineating anomalous vascular supply. Cystic changes were also observed in the basal area of the sequestration in all patients. Four children remained asymptomatic and one infant presented at 10 months of age with pneumonia. The mean age at surgical resection was 6.8 months (range 2-10). Histopathological examination confirmed intralobar pulmonary sequestration with associated Stocker type 2 congenital cystic adenomatoid malformation in two patients and extralobar pulmonary sequestration with associated Stocker type 2 congenital cystic adenomatoid malformation in three patients. The mean period of follow up was four years (range 1-8). The children remain well and are developing normally. CONCLUSIONS The importance of seeking an anomalous blood supply in children with congenital lung lesions is emphasised. Pulmonary sequestration and congenital cystic adenomatoid malformation probably share a common embryogenesis despite diverse morphology. The natural history of antenatally diagnosed lung masses is variable. Early postnatal surgical resection of pulmonary sequestration with cystic adenomatoid malformation is recommended. Surgical excision should be conservative, sparing the normal lung parenchyma.

Abstract
Antenatal diagnosis of lung abnormalities by ultrasound has been a much more frequent occurrence in recent years. There is a range of appearances from uniform increased echogenicity through to lesions containing large echo-free areas. Bilateral uniformly increased echogenicity has a poor outlook but in all other situations outcome cannot be accurately predicted from an early second trimester scan. Follow-up through pregnancy often allows a fairly accurate prognosis to be made but the appearance of the lesion does not accurately predict histology. A conservative approach to the antenatal management of unilateral lesions is recommended with long-term postnatal follow-up for all lesions because of the unknown long-term outcome for the lesions, many of which are symptomatic postnatally.

Abstract
Although significant anomalies of the fetal thorax are uncommon, with improvement in high-resolution ultrasonography, more of these lesions are being diagnosed prenatally. Accurate and specific prenatal diagnosis is important because different lesions have different natural histories and prognosis. Prenatal MRI is an increasingly important adjunct for identification and differentiation of these lesions and may help determine in selected cases when and if in utero fetal intervention is indicated.

Abstract
Congenital cystic adenomatoid malformation and bronchopulmonary sequestration are congenital lung tumors that are classically described as having distinct embryology, pathology, and natural history. The authors treated six patients who had prenatally diagnosed lung masses that displayed clinicopathologic features of both lesion types. At prenatal diagnosis (19 to 30 weeks' gestation), all six lesions were classified sonographically as congenital cystic adenomatoid malformation, and none of the masses appeared to have a systemic arterial blood supply as seen by color flow Doppler study. Two of the six masses showed size regression antenatally. At the time of surgery, all six lesions had a systemic vessel directly from the aorta--five cases were consistent grossly with an intralobular bronchopulmonary sequestration, and one case was consistent with an extralobular bronchopulmonary sequestration. However, all six lesions displayed congenital cystic adenomatoid malformation histology. Hydrops developed in one fetus with a huge mass, and that fetus underwent successful fetal surgical resection (left lower lobectomy) at 22 weeks' gestation with delivery at 35 weeks' gestation. One neonate with a large extralobular bronchopulmonary sequestration was treated with resection and extracorporeal membrane oxygenation (ECMO) but died of pulmonary hypoplasia. Four other patients who had much smaller masses underwent elective lower lobectomy after birth. These findings emphasize the importance of seeking an anomalous blood supply in patients who have congenital lung lesions. These "hybrid" cases suggest a similar embryological origin for congenital cystic adenomatoid malformation and bronchopulmonary sequestration.

Abstract
The bronchopulmonary-foregut malformations (BPFM) are usually sporadic, solitary cystic hamartomas involving conducting airways, arteries, venous drainage, and lung parenchyma. Transitional, compound hamartomas exist, and only their morphology is well-known. Between 1984-1994 we encountered and studied 10 unrelated patients and a stillborn infant with BPFM (out of 24,000 families). Ten were diagnosed in utero and one at birth as having congenital cystic adenomatoid malformation of the lung (CCAML). Postnatally, two diagnoses (20%) were corrected to bronchogenic cyst (BC) and diaphragmatic hernia, respectively. Bilateral lung involvement was present in 1 patient, and in 2 there was a considerable macroscopic regression of the hamartoma. Histologic studies of the six resected CCAML confirmed the diagnosis and implied dysregulated paracrine growth with its cellular and extracellular growth factors, protooncogenes, oncogenes, cytokines, cell-adhesive molecules, and receptors of these regulatory peptides, and their complex interactions as developmental morphogens in time and space.
