Congenital pulmonary airway malformation and duplication cyst
3 month old female who presents for follow up of a finding on antenatal imaging.
Loading Stack -
0 images remaining
- Cluster of thin walled cystic spaces in the superior segment left lower lobe
- A low attenuation region of lung extends inferiorly to the level of the diaphragm,
- Atelectasis adjacent the cystic lesion and within the dependent portions of the right lung
- Aorta has a normal appearance with no visible aberrant vessel supplying this region
- NG with tip in the stomach, with contrast within the stomach lumen
- Homogeneous hypodense round filling defect posterolateral to the gastro-esophageal junction
- Normal appearance of the upper abdominal viscera and skeletal structures
The cystic lesion is consistent with a congenital pulmonary airway malformation. The hypodense lesion within the stomach is consistent with a duplication cyst.
The histological diagnosis of congenital airway pulmonary malformation (CPAM) was confirmed following left lower lobectomy. The duplication cyst has not been resected.
