Area of Science:

  • Thoracic Surgery
  • Pulmonary Medicine
  • Surgical Pathology

Background:

  • A 65-year-old female non-smoker presented with a 6-month history of chest tightness.
  • Chest computed tomography (CT) revealed four distinct lesions: two nodules in the left upper lobe (S3 and S4 segments), one nodule in the left lower lobe, and a ground-glass opacity (GGO) in the right upper lobe.

Observation:

  • Synchronous bilateral thoracoscopic wedge resections were performed for nodule investigation.
  • Intraoperative frozen section pathology indicated malignancy in the left upper lobe nodules, a benign lesion in the left lower lobe, and atypical adenomatous hyperplasia in the right upper lobe GGO.

Findings:

  • Final pathology confirmed well-differentiated adenocarcinoma (pT1bN0M0, IA) in the left S3 segment and moderately to poorly differentiated adenocarcinoma (pT1aN0M0, IA) in the left S4 segment.

  • The left lower lobe nodule was diagnosed as cryptococcal granuloma, and the right upper lobe GGO as adenocarcinoma in situ.
  • A left upper lobectomy with lymph node dissection was performed based on intraoperative findings.
  • Implications:

    • This case highlights a successful surgical approach for managing heterogeneous bilateral quadruple pulmonary nodules.
    • The presented surgical algorithm offers a potential strategy for similar complex thoracic cases.
    • Early and accurate diagnosis through intraoperative pathology is crucial for guiding surgical management.
