Folded lung: a masquerader of malignancy.

S K Ohri1, E R Townsend

Summary

Folded lung, a rare condition, can mimic lung cancer on CT scans. Exploratory thoracotomy is recommended for diagnosis and potential treatment, especially in fit patients, to avoid misdiagnosis from imaging or biopsy.

Area of Science:

  • Pulmonology
  • Thoracic Surgery
  • Diagnostic Imaging

Background:

  • Folded lung (also known as}'}'lingula syndrome') is a rare condition that can present with symptoms that may be mistaken for other pulmonary pathologies.
  • The differential diagnosis of folded lung is crucial, particularly when considering malignancy.
  • Computed tomography (CT) scans may show characteristic features of folded lung, but these can be mimicked by lung carcinoma.

Purpose of the Study:

  • To report on cases of folded lung observed over an 8-year period.
  • To discuss the diagnostic challenges posed by folded lung, especially in differentiating it from malignancy.
  • To evaluate the role of exploratory thoracotomy in the diagnosis and management of folded lung.

Main Methods:

  • Retrospective review of four cases of folded lung diagnosed between 1982 and 1990.
  • Description of clinical presentation, imaging findings (including CT scans), and surgical outcomes.
  • Analysis of diagnostic accuracy and management decisions.

Main Results:

  • Four cases of folded lung were identified over an 8-year period.
  • Three patients underwent exploratory thoracotomy, with no subsequent morbidity or mortality.
  • One patient declined surgery.
  • CT scan findings, while sometimes characteristic, can be confused with those of lung carcinoma.

Conclusions:

  • Folded lung can present diagnostic challenges, with imaging features that may mimic malignancy.
  • Exploratory thoracotomy is a safe and effective procedure for establishing a definitive diagnosis of folded lung.
  • In patients fit for surgery, exploratory thoracotomy is advisable to confirm the diagnosis and allow for resection if necessary, thereby avoiding risks associated with false-negative imaging or biopsy.
