CTICasesCongenital Hyaline Membrane Deficiency / Large Bullous Emphysema

Imaging findings
The images showed large bullous formations with an almost 'vanishing lung' appearance due to significant mass effect on the adjacent lung parenchyma. The entire lungs were abnormal, characterized by panlobular emphysema and numerous bullae. Following surgical bullectomy of a dominant bulla on the right, the mass effect was resolved, but significant residual bullous formations remained.
Key takeaways
Congenital hyaline membrane deficiency, as listed by the clinicians, can manifest as severe panlobular emphysema with large bulla formations, often leading to recurrent pneumothoraces. The imaging appearance can resemble severe alpha-1 antitrypsin deficiency, particularly if the patient is a smoker. Management may involve bullectomy to address dominant bullae, but lung transplant candidacy can be complex.
