Pneumatoceles or Not? Case Reports on Pulmonary Cystic Lesions in Infants.

Abstract

Pulmonary cystic lesions in infants are uncommon and can present diagnostic challenges due to overlapping radiologic features with other cystic lung conditions. We present 2 cases of left lung cystic lesions in infants. Initial high-resolution computed tomography (HRCT) suggested differential diagnoses, including pneumatocele, type I congenital pulmonary airway malformation (CPAM), or a solitary cystic lymphangioma. Definitive diagnosis was achieved through histopathological examination after left lower lobectomy and resection of the lesion. These cases highlight the challenges in accurately diagnosing pulmonary cystic lesions, given the limitations of imaging alone.
