Diagnosis With Brief Discussion

Diagnosis
CPAM type I with combined pneumonia
Radiologic Findings
Chest CT and radiograph show essentially unchanged ill-defined low attenuating lesion with variable sized cysts in LLL. Newly appeared air-fluid level within cysts and consolidation in LLL.

The patient underwent left lower lobectomy and was pathologically diagnosed as CPAM(type 1) combined with pneumonia.

Brief Review
Congenital pulmonary airway malformations (CPAM) are multicystic masses of segmental lung tissue with abnormal bronchial proliferation. CPAMs are considered part of the spectrum of bronchopulmonary foregut malformations. The term congenital pulmonary airway malformation has been recommended as preferable to congenital cystic adenomatoid malformation.
Only three types of CPAM are distinguished on imaging: large cyst CPAM (type I) and small cyst CPAM (type II), which constitute macrocystic CPAM; and microcystic or solid type lesions (type III), which have cysts less than 5 mm in diameter with no discernible cystic spaces.
