Summary
Extralobar pulmonary sequestration, a rare lung malformation, was found incidentally in a 65-year-old man. This posterior mediastinal mass was supplied by an artery from the descending aorta.
Area of Science:
- Thoracic Surgery
- Diagnostic Imaging
- Congenital Malformations
Background:
- Pulmonary sequestration is a rare congenital lung malformation.
- Extralobar pulmonary sequestration (EPS) involves lung tissue separate from normal lung parenchyma.
- Posterior mediastinal masses can represent various pathologies, requiring accurate diagnosis.
Observation:
- A 65-year-old male patient presented with an incidentally detected posterior mediastinal mass.
- Preoperative imaging suggested a mediastinal lesion.
- Surgical exploration revealed the mass attached to the paravertebral region at T7.
Findings:
- The mass was identified as an extralobar pulmonary sequestration.
- A feeding artery originating from the descending aorta supplied the sequestration.
- This presentation is unusual, with only two prior reports of EPS in the posterior mediastinum.
Implications:
- Highlights the importance of considering rare diagnoses for posterior mediastinal masses.
- Underscores the variability in presentation and location of extralobar pulmonary sequestration.
- Contributes to the limited literature on posterior mediastinal extralobar pulmonary sequestration, aiding future case identification and management.
