Pulmonary agenesis is an inborn lung underdevelopment that is rare and potentially lethal. [1] The disorder is caused by a complete developmental arrest of the primitive lung during embryonic life, and it is often associated with other developmental defects. [2]
Incidence of congenital malformations associated with tracheal agenesis. Results were obtained from a total of 32 individual case studies. [11]The classic in-utero symptoms of tracheal agenesis are an absence of the trachea leading to congenital high airway obstruction syndrome, [12] [13] lung distention, polyhydramnios, heart malformations, heart displacement and hydrops fetalis.
Asplenia with cardiovascular anomalies, also known as Ivemark syndrome and right atrial isomerism, [1] is an example of a heterotaxy syndrome.These uncommon congenital disorders are characterized by defects in the heart, spleen and paired organs such as the lungs and kidneys.
Body tissue and special cells from each side of the head grow toward the center of the face. They join to make the face. [14] A cleft means a split or separation; the "roof" of the mouth is called the palate. [15] A congenital malformation is a physical anomaly that is deleterious, i.e. a structural defect
Congenital pulmonary airway malformation in a fetus, ultrasound at 19 weeks - transverse. Stomach on left image; heart on right image: displaced to right by cystic mass. The earliest point at which a CPAM can be detected is by prenatal ultrasound. The classic description is of an echogenic lung mass that gradually disappears over subsequent ...
Medical diagnosis of pulmonary hypoplasia in utero may use imaging, usually ultrasound or MRI. [12] [13] The extent of hypoplasia is a very important prognostic factor. [14]One study of 147 fetuses (49 normal, 98 with abnormalities) found that a simple measurement, the ratio of chest length to trunk length, was a useful predictor of postnatal respiratory distress.

Slavotinek (2004) reviewed the phenotypes of 52 reported cases of Fryns syndrome and reevaluated the diagnostic guidelines. [13] She concluded that congenital diaphragmatic hernia and distal limb hypoplasia are strongly suggestive of Fryns syndrome, with other diagnostically relevant findings including pulmonary hypoplasia, craniofacial ...
