A rare case of symptomatic congenital lobar emphysema in an adolescent female who underwent expectant management of a congenital pulmonary malformation: a case report
Bibliographic record
Abstract
Background: Asymptomatic congenital pulmonary airway malformations (CPAMs) and congenital lobar emphysema (CLE) may safely be observed, though little is known about how many patients later require surgery. The management of these lesions remains controversial, as limited research exists on which patients later require surgery. Notably, there are few reported cases where patients become symptomatic and require definitive treatment beyond childhood. Case Description: We present the rare case of a 17-year-old female who developed dyspnea on exertion associated with pre-syncope, following diagnosis of a CPAM at birth. She had undergone surveillance until 2 years of age. The decision to proceed with a left upper lobectomy via thoracotomy was made, for treatment of her symptoms. During the surgery, one lung ventilation suggested that oxygenation had likely limited to the patient's healthy lung, prior to intervention. The surgery was uncomplicated, and her recovery was uneventful. Pathology revealed CLE. Conclusions: This case highlights that congenital lung malformations should remain in the differential diagnosis of patients presenting in adolescence or adulthood with new onset respiratory symptoms. For patients with a history of untreated congenital lung pathology, it is important to consider the presence of adhesions and loss of domain in perioperative planning. This case also highlights the ongoing need for research on the prognostication of these lesions to better inform surveillance.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
