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.
婴儿肺部囊性病变并不常见，由于其放射学特征与其他肺部囊性疾病重叠，可能带来诊断挑战。我们报告2例婴儿左肺囊性病变。最初的高分辨率计算机断层扫描（HRCT）提示了鉴别诊断，包括肺气囊、I型先天性肺气道畸形（CPAM）或孤立性囊性淋巴管瘤。通过左下肺叶切除及病变切除后的组织病理学检查得以明确诊断。鉴于仅靠影像学存在局限性，这些病例凸显了准确诊断肺部囊性病变的挑战。
