Atypical antenatal presentation of an unusual nonmucinous papillary variant of giant congenital pulmonary airway malformation masquerading as congenital diaphragmatic hernia with volvulus

Abstract

We report a case of a huge congenital pulmonary airway malformation (CPAM) that was referred as congenital diaphragmatic hernia (CDH). Initial ultrasound evaluation revealed a huge cystic lesion with septations, in the thorax, causing mediastinal shift and compression effects, suggesting the possibility of a thoracic lymphangioma, or bowel herniation with obstruction. A fetal magnetic resonance imaging reported possible bowel herniation through a posterior defect in the diaphragm, with volvulus, reinforcing the diagnosis of CDH. It was only on autopsy and subsequent histopathology examination that the diagnosis of a rare variant of CPAM–nonmucinous papillary type, could be made. To the best of our knowledge, a CPAM this huge has not been reported prenatally at this gestation. We recommend considering the potential diagnosis of CPAM in any thoracic cystic irrespective of its size or appearance.

“…Por lo general, se diagnostican mediante ecografía prenatal como una masa bien delimitada, que puede presentar un componente quístico e involucrar los tractos de salida y que típicamente se encuentra asociado a derrame pericárdico (3) . El diagnóstico diferencial incluye otros tumores cardíacos como rabdomiomas, linfangiomas, fibromas, mixomas y hemangiomas, como así también tumores pulmonares y mediastínicos (1)(2)(3)(4)(5) .…”
