Summary
Syndrome
Cystic adenomatoid malformation of the lung (CAML)
Definition
CCAM is a pulmonary hamartoma of the lung resulting from excessive growth of the terminal bronchioli leading to alveolar growth arrest. The lesion tends to be unilateral. The hamartoma may contain air or liquid and is connected to the bronchial system. Blood supply comes from the pulmonary circulation. In up to 20% CCAM is associated with malformations such as congenital diaphragmatic hernia (CDH), hydrocephalus, malformation of the bones, kidney, and small intestines.
Epidemiology
Incidence approx. 1:30 000 (0.33/1000)
Pathophysiology
Compression of surrounding organs, heart failure, hydrops, and lung hypoplasia are possible
Possible decrease or increase of mass
Poor prognosis in CCAM with fetal hydrops and polyhydramnios
Prenatal diagnosis
Ultrasound: macrocystic (diameter >5 mm) and microcystic (diameter <5 mm) forms
Prenatal DDx
Sequestrated lung, tumour, CDH (see pp. 404–9), lobar pulmonary emphysema, bronchogenic cyst
! A congenital cystic adenomatoid malformation (CCAM) can be diagnosed prenatally. The expectant mother must be transferred to a tertiary perinatal center prior to delivery.
Prenatal therapy
Puncture of a macrocystic malformation may be required
In specific cases thoracoamniotic shunting may be considered
Prenatal surgical treatment is not yet established
Clinical presentation
(Tachy) dyspnea
Pallor/cyanosis
O2 requirement varies
Hydrops fetalis and PPHN are possible
Postnatal DDx
Without a prenatal diagnosis: RDS, pneumothorax, aspiration, CDH, pleural effusion
Diagnosis in the delivery room
Auscultation: faint breathing sounds on the affected side
Blood gas analysis and blood glucose, laboratory work-up, and if necessary blood culture
HIV/hepatitis serology, blood type and screen/cross
