Rounded atelectasis, a condition involving pleural fibrosis and lung collapse, can mimic tumors. This case highlights its distinct features, differentiating it from malignancy in a patient with asbestos exposure and smoking history.

Area of Science:

  • Pulmonology
  • Thoracic Surgery
  • Radiology

Background:

  • Rounded atelectasis, also known as Blesovsky's syndrome, is characterized by pleural fibrosis, visceral pleural folding, and adjacent lung atelectasis.
  • It can be mistaken for peripheral lung tumors or mesothelioma on imaging.
  • Potential causes include pleural effusions or contraction of pleural fibrosis, often associated with asbestos exposure.

Observation:

  • A 44-year-old male smoker with occupational asbestos exposure presented with chest pain and dyspnea.
  • Chest X-ray and CT scan revealed a round peripheral mass in the left lower lobe, suggestive of a tumor.
  • Fine needle aspiration biopsy showed atypical cells, leading to a thoracotomy.

Findings:

  • Surgical resection revealed a pleural plaque with underlying folded visceral pleura and fibrotic, atelectatic lung parenchyma.

  • Histopathological examination confirmed rounded atelectasis, with no evidence of malignancy.
  • The characteristic 'comet-tail' sign was observed on imaging, aiding in diagnosis.

    • Implications:

    • This case underscores the importance of recognizing rounded atelectasis as a differential diagnosis for peripheral lung masses, especially in patients with relevant exposure history.
    • Accurate radiological interpretation and consideration of benign conditions can prevent unnecessary aggressive interventions.
    • Understanding the pathogenesis of rounded atelectasis is crucial for appropriate patient management and diagnosis.
