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
