Congenital overinflation of lung is underdiagnosed prenatally as the imaging features of the same are not well described. We describe a very rare case of central variety of congenital overinflation, secondary to right mainstem bronchial stenosis, not previously described in our knowledge, which presented as an enlarged homogenous echogenic/hyperintense lung with cardio-mediastinal shift and was misdiagnosed as congenital pulmonary airway malformation (CPAM). We reviewed imaging features helpful in prenatal diagnosis of this condition on ultrasound and magnetic resonance imaging and discussed an approach for differential diagnosis. The congenital central overinflation may be considered in prenatal detected echogenic lung lesions with the absence of cysts or systemic arterial supply and presence of hypervascularity or dilated bronchi within the lesion.
先天性肺过度充气在产前诊断不足，因为其影像学特征尚未得到充分描述。我们描述了一例非常罕见的中央型先天性肺过度充气病例，继发于右主支气管狭窄，据我们所知此前未见报道，其表现为均匀增大的高回声/高强度肺伴心纵隔移位，被误诊为先天性肺气道畸形（CPAM）。我们回顾了有助于超声和磁共振成像产前诊断该疾病的影像学特征，并讨论了鉴别诊断方法。对于产前检测到的无囊肿或体循环动脉供应、病变内有血管增多或支气管扩张的高回声肺病变，可考虑先天性中央型肺过度充气。
