Summary
Churg-Strauss Syndrome (CSS) was diagnosed in a Japanese man via pleural biopsy, a novel diagnostic method. Treatment with oral prednisolone effectively improved his symptoms of fever and joint pain.
Area of Science:
- Pulmonology
- Rheumatology
- Pathology
Background:
- Churg-Strauss Syndrome (CSS), also known as eosinophilic granulomatosis with polyangiitis, is a rare systemic vasculitis characterized by asthma, eosinophilia, and granulomatous inflammation.
- Diagnosis typically involves a combination of clinical presentation, laboratory findings (e.g., eosinophilia, elevated inflammatory markers), and imaging studies.
- While various biopsy sites have been used, diagnosis via pleural biopsy is less commonly reported.
Observation:
- A 51-year-old Japanese male presented with high fever and migratory polyarthralgia affecting knees, elbows, and shoulders.
- Imaging revealed massive bilateral pleural effusions on chest roentgenogram and computed tomography (CT).
Findings:
- Pleural biopsy demonstrated characteristic findings of eosinophilic infiltration and necrotizing granulomas, leading to the diagnosis of CSS.
- The patient showed significant clinical improvement following treatment with oral prednisolone.
Implications:
- This case highlights the diagnostic utility of pleural biopsy in identifying Churg-Strauss Syndrome, particularly when other sites are inconclusive or inaccessible.
- Establishing CSS diagnosis through pleural biopsy can facilitate timely and appropriate treatment, potentially improving patient outcomes.
- This report contributes to the literature by presenting the first documented instance of CSS diagnosed via pleural biopsy.
