Imaging characteristics and the accuracy of computered tomography in predictability of congenital pulmonary airway malformation

SUMMARY

Perpose: To describe imaging characteristics and to analyse the value of CT-scanner in treatment of congenital pulmonary airway malformation (CPAM).

Material and Methods: Retrospective imaging description of chest CT-scanner was done on 61 children patients suspected of CPAM on clinical examination in national chidren Hospital from January 2011 to June 2014. in which 33 cases were diagnosed of CPAM on histopathology. The value of CT-scanner were analysed in diagnosed of CPAM.

Results: CPAM is common in right lower lobe. It contains one or multicytic mas (≥ 5 cysts) with cystic wall ≤ 2.5 mm, no private feeding artery. There are statitistically significant different between diameter of largest cysts in each other típ. CPAM is an air cytic (45.6%), air-fluid level cystic (9.1%), fluid cystic mass (27.2%) or complex mass (18.1%). The sensitivity of CT in diagnosis CPAM is 100%, specificity is 75%, and accuracy is 88.5%.

Conclusions: CPAM demonstrates a variety of CT appearances based on the type of CPAM. CT has high accuracy in diagnosis CPAM.

Keywords: Congenital pulmonary airway malformation (CPAM), computered tomography (CT).
