ELS are often discovered in infants who present with other conditions for example, heart failure, polyhydramnios, or prematurity. 6. Presentation The age of presentation is variable in children with ELS. [ncbi.nlm.nih.gov]

Infants present with cough, wheezing, respiratory distress, and cyanosis. Older children may present with recurrent chest infections. [emedicine.medscape.com]

• Swelling

  Another indicator of serious problems is swelling in the placenta. Placental swelling is associated with hydrops and is a sign of “mirror syndrome,” which means that the mother’s life could be at risk. [cincinnatichildrens.org]

  Because of a hyperdynamic cardiovascular state, the mother develops symptoms that are similar to pre-eclampsia and may include vomiting, hypertension, peripheral edema (swelling of her hands or feet), protein in her urine and pulmonary edema (fluid in [fetus.ucsf.edu]

  This can sometimes lead to the buildup of extra fluid around the baby’s heart, lungs, and belly, as well as swelling of skin, called hydrops. Survival is very poor if the baby develops hydrops that does not respond to medicine. [ohiofetalmedicine.org]

• Respiratory Distress

  Large cyst presents with respiratory distress and cyanosis in newborns. BC may be detected as incidental findings on chest radiographs. Newborns with large cysts can develop respiratory distress, cyanosis, and feeding difficulty. [ncbi.nlm.nih.gov]

  CPAM symptoms: Respiratory distress This is the most common symptom in most newborns with a diagnosis of CPAM. [childrensnational.org]

  Neonates may present with mild-to-moderate respiratory distress. Mediastinal shift may be present, with hyperresonance and decreased breath sounds on the involved side. Infants present with cough, wheezing, respiratory distress, and cyanosis. [emedicine.medscape.com]

  After delivery, the patient had a good Apgar score, a birth weight of 3450g (50th centile), and immediately respiratory distress with increasing oxygen need. [latunisiemedicale.com]

  Severe respiratory distress may warrant an emergent surgical resection. [ispub.com]

• Tachypnea

  Tachypnea is the most common sign encountered in the newborn period, reflecting respiratory distress. [childrensnational.org]

  Typical presenting signs include tachypnea, respiratory distress including grunting, chest retractions, and cyanosis. Childhood presentation Thirty percent of CPAMs are diagnosed after the neonatal period. [clinicaladvisor.com]

  The commonest presentation of CCAM in postnatal life is progressive respiratory distress including tachypnea, grunting, retraction, and cyanosis; and in adults it usually presents as repeated chest infections. [lungindia.com]

  The most common clinical presentation is progressive respiratory distress including tachypnea, grunting, retractions and cyanosis.2 Upon physical examination, there may be prominence of the affected side of the chest, ipsilateral hyperresonance and decreased [ispub.com]

• Sputum

  […] supply, venous drainage • MRI or CT now used to evaluate for systemic artery and should replace arteriography • US prenatal / neonatal --homogeneous echogenicity (ELS) • Probably acquired in most cases – Only 50% discovered before age 20 • Sx: cough, sputum [learningradiology.com]

  Sputum staining for acid-fast organisms was negative, but Haemophilus parainfluenzae was grown on culture media. Left upper lung biopsy revealed CPAM type 1 with aspergilloma ( Figures 2 and 3 ). [dovepress.com]

  Bronchoscopic examination, bronchoalveolar lavage, sputum and bronchial aspirate were negative for malignancies. [diagnosticpathology.biomedcentral.com]

• Respiratory Insufficiency

  Pulmonary lymphangiectasis is congenital, but symptoms of respiratory insufficiency usually do not appear until adulthood. Congenital lobar emphysema Massive overinflation of one or more lung lobes occurs postnatally in congenital lobar emphysema. [emedicine.medscape.com]

  Even after decompression and resolution of hydrops, surviving neonates often have respiratory insufficiency. Figure 7. Right CPAM (19 weeks). [iame.com]

• Stridor

  High tracheal BC may present with stridor. Cysts may communicate with the airway and become infected and rupture. Paraesophageal cyst may give rise to dysphagia. Pericardial BC may present with Superior Vena Cava obstruction. [ncbi.nlm.nih.gov]

  Respiratory distress may result in a stridor or wheeze. Airtrapping may lead to emphysema, atelectasis, or both. Dysphagia, chest pain, and epigastric discomfort can occur. See the images below. Bronchogenic cyst. [emedicine.medscape.com]

Early diagnosis and prompt treatment offer the possibility of absolutely normal lung development. The treatment of asymptomatic patients with lung malformations is controversial, because the prognosis of these diseases is unpredictable. [ncbi.nlm.nih.gov]

Prenatal Steroid Treatment A new treatment for fetuses with microcystic CPAMs that have hydrops has emerged here at UCSF. [fetus.ucsf.edu]

Treatment People with congenital lobar emphysema or pulmonary cysts may not need any treatment, while others may need surgery to remove the affected lobe (lobectomy). [rbhh-specialistcare.co.uk]

These limitations strongly impact the treatment of these pulmonary pathologies diagnosed during the antenatal period. The advancement of prenatal imaging has modified the treatment of congenital pulmonary malformations. [journals.lww.com]

Treatment consists of surgical excision, sometimes as early as three months. [drranjansuri.com]

Treatment and prognosis There can be a wide spectrum in prognosis. [radiopaedia.org]

Type IV : 15%, large cysts up to 10 cm lined by flattened epithelium; good prognosis; similar to grade 1 pleuropulmonary blastoma although less cellular; sample generously to rule out blastoma Clinical features Associated with stillbirth, neonatal distress [pathologyoutlines.com]

Postnatal and in adult patients, lobectomy is the treatment of choice for symptomatic cases. [5], [8] Prognosis also depends on Stocker type, type I lesions carry overall good prognosis. [jacpjournal.org]

In type II lesion, it is the associated anomalies that determine the prognosis. Type III lesions carry bad prognosis as they are usually large and presents with cardiovascular compromise. [lungindia.com]

The treatment of asymptomatic patients with lung malformations is controversial, because the prognosis of these diseases is unpredictable. The management of these lesions depends on the type of malformation and symptoms. [ncbi.nlm.nih.gov]

Conflict of Interest: None DOI: 10.4103/2320-8775.158854 Congenital cystic adenomatoid malformations (CCAMs), also known as congenital pulmonary airway malformation is a developmental, non-hereditary, hamartomatous abnormality of lung with unknown etiology [jacpjournal.org]

The etiology remains unknown. Hamartomatous change in the terminal bronchioles or aberrant embryogenesis at or before the seventh gestational week producing cystic distortion of the lung architecture is suspected [1]. [ctsnet.org]

Huge fetal lung lesions have reproducible pathophysiologic effects on the developing fetus. Esophageal compression by the thoracic mass causes interference with fetal swallowing of amniotic fluid and results in polyhydramnios. [chop.edu]

When hydrops is present, risk of fetal demise is much greater without in utero surgery to correct the pathophysiology. The greatest period of growth is during the end of the second trimester, between 20–26 weeks. [en.wikipedia.org]

Pathophysiology Congenital cystic adenomatoid malformation is an uncommon developmental lung anomaly that is thought to occur early in fetal lung development, around the fifth to the eighth weeks of gestation. [ispub.com]

Wheezing is frequently associated with CPMs, potentially induced by the pathophysiological mechanisms underlying the CPM. Surgical removal of the CPM had no significant impact on these symptoms. [pediatrics.aappublications.org]

The goals of the operation are to; 1- prevent of infection in the abnormal area of lung within the CPAM, 2- expand of the CPAM, which will compress normal lung tissue, and 3- prevent the CPAM from possibly becoming concerns in the future. [childrensnational.org]

The mass can also push on the heart and the esophagus of the fetus, putting an extra workload on the heart and preventing the fetus from swallowing amniotic fluid. [fetus.ucsf.edu]

Surgeons remove the affected lobe to prevent further damage to the lung. Most doctors recommend waiting until your child is between 6 months and 1 year old before surgery. [childrens.com]

To prevent this from happening, either fetal surgery or early delivery is necessary. In the vast majority of cases however, babies do well and have normal development and lung function. [cardinalglennon.com]
