Inflammatory Bowel Disease

Epidemiology

  • Pleural effusions occurs in <10% of IBD cases
  • Serositis rarely predates the onset of IBD symptoms
  • Most cases are young males

Etiology

  • Crohn’s Disease (see [[Crohns Disease]])
  • Ulcerative Colitis (see [[Ulcerative Colitis]])

Physiology

  • Serositis -> thickened, inflammed pleura
  • Pericardial involvement has been also reported (occasionally in conjunction with pleural involvement)

Diagnosis

  • Pleural Bx: non-specific inflammation without granulomas
  • CXR/Chest CT patterns:
    • Almost always unilateral
