Hypoplasia of the left lung presenting as hemoptysis: A case report
Insights
Congenital pulmonary dysplasia (CPD), a rare lung anomaly, can present with hemoptysis, a previously unreported symptom. Surgical intervention for left pulmonary hypoplasia successfully resolved hemoptysis in an 11-year-old patient.
Area of Science:
- Pediatric Pulmonology
- Thoracic Surgery
Background:
- Congenital pulmonary dysplasia (CPD) encompasses a spectrum of lung developmental disorders, often presenting with recurrent respiratory infections and dyspnea.
- While various manifestations exist, hemoptysis is an exceptionally rare clinical presentation for CPD.
Observation:
- This case report details an 11-year-old girl with a history of left pulmonary hypoplasia, a form of CPD, who presented with mild to moderate hemoptysis.
- The patient had no other significant complications related to her congenital lung anomaly prior to the hemoptysis.
Findings:
- Left pulmonary hypoplasia was diagnosed, and the patient underwent a left lower pulmonary lobe resection.
- Post-operatively, the patient experienced a favorable recovery, with complete resolution of hemoptysis and cough.
Implications:
- This case highlights that hemoptysis, though rare, can be a presenting symptom of congenital pulmonary dysplasia.
- Accurate diagnosis via contrast-enhanced CT and bronchoscopy, followed by appropriate surgical management, is crucial for managing CPD and its complications.
Rationale:
Congenital pulmonary dysplasia (CPD), a congenital lung anomaly, is a heterogeneous group of developmental disorders with diverse clinical and imaging manifestations, including pulmonary agenesis, pulmonary aplasia, and pulmonary hypoplasia. Patients with CPD always have recurrent respiratory tract infections, dyspnea, and/or wheezing. To the best of the author's knowledge, no case of CPD with mild to moderate hemoptysis has been reported so far. Considering the rarity of this presentation, we herein report a case of hemoptysis caused by CPD.
Patient Concerns:
We report on an 11-year-old girl who survived for 11 years with hypoplasia of the left lung without any associated complications except hemoptysis.
Diagnosis:
Left pulmonary hypoplasia.
Interventions:
The patient underwent left lower pulmonary lobe resection.
Outcomes:
The patient recovered favorably after the operation, and no complications were observed. The hemoptysis was controlled and the cough disappeared after the surgery.
Lessons:
CPD is a life-threatening disorder rarely encountered in the clinic, which plays an important role in various pediatric respiratory diseases. Misdiagnosis or delayed diagnosis of pulmonary malformations results in unnecessary treatments and hospitalization. The patients should undergo pulmonary contrast-enhanced CT and bronchoscopy for accurate and timely diagnosis, followed by surgical treatment.
