Idiopathic lobar emphysema (ILE) and bronchopulmonary sequestration (BPS) are two of the well-characterized pulmonary malformations. An antenatally detected case of a left bronchopulmonary malformation (BPM) was clinicoradiologically diagnosed to be a left upper lobar emphysema with isolated dextrocardia in the neonatal period. Besides the emphysematous left upper lobe, an accessory lobe akin to an extra lobar BPS was an operative surprise. Histopathological examination of both excised lobes led to a revised diagnosis of a 'hybrid' malformation comprising lobar emphysema and extra lobar BPS. The postoperative recovery was uneventful. The observations suggest that BPS and ILE may be interim entities in a continuum of abnormal embryogenesis. Such a hybrid malformation has not been hitherto reported.

A Series of 40 Congenital Lung Malformation Cases and the Informative Value of CPAM Lesion Ratios.

Introduction: In this single-center retrospective analysis, we present case data and insights gathered over the past eight years. Additionally, we computed postnatal, pre-therapy lesion-to-lung ratios of Congenital Pulmonary Airway Malformations (CPAMs) to retrospectively assess potential outcome prediction using lesion-to-lung ratios.
Methods: Data were collected between 2015 and 2022.

Aim Of The Study: Patients with congenital lung malformation (CLM) may present pulmonary inflammatory changes. However, little is known about the factors influencing local inflammation. The aim of this study was to evaluate the factors that may affect inflammatory changes in CLM.

Emphysema, marked by irreversible lung tissue destruction, poses challenges in progression prediction due to its heterogeneity. Early detection is particularly critical for patients with Alpha-1 Antitrypsin Deficiency (AATD), a genetic disorder reducing ATT protein levels. Heterozygous carriers (PiMS and PiMZ) have variable AAT levels thus complicating their prognosis.

These require initial proof-of-concept demonstration that treatment administration increases alpha-1 antitrypsin (AAT) levels and/or anti-neutrophil elastase inhibitory capacity (ANEC) in the lung. Early-phase studies often encounter high interindividual variability of BAL results, primarily stemming from the inherent dilution characteristics of returned BAL fluid.

Background: Pneumothorax is a major complication after endoscopic lung volume reduction with valves, with a prevalence of up to 34%. Although some patients benefit from valve implantation despite pneumothorax, others are significantly impaired after lung collapse.
Research Question: What are the differences in the severity grades of pneumothorax and how do these affect clinical practice?
Study Design And Methods: This single-center retrospective study analyzed patients undergoing endoscopic valve implantation with and without pneumothorax after intervention.
