Pseudochylothorax (Cholesterol Effusion)

ICD-10 Code
J94.8

Clinical Criteria for Pseudochylothorax (Cholesterol Effusion).

Clinical Presentation & Protocol

Patient Usually Complains Of

Patient presents with chronic, stable pleural effusion, often associated with long-standing underlying pulmonary pathology (e.g., rheumatoid pleurisy, chronic tuberculous empyema). Reports progressive dyspnea, chest tightness, or asymptomatic incidental finding on imaging. Denies acute infectious symptoms or recent trauma.

Clinical Examination Findings

Physical examination reveals decreased chest wall expansion, dullness to percussion, and diminished breath sounds over the affected hemithorax. Absence of acute distress. Thoracentesis yields characteristic opalescent, gold-colored, or "cholesterol-rich" fluid. Laboratory analysis confirms high cholesterol levels (>200 mg/dL) and low triglyceride levels (<50 mg/dL), with presence of cholesterol crystals on microscopy.

Treatment Protocol

Management focuses on addressing the underlying chronic inflammatory process. Therapeutic thoracentesis is reserved for symptomatic relief of dyspnea. Surgical intervention (pleurectomy or decortication) may be considered in cases of persistent, symptomatic, or trapped lung. Close monitoring for potential complications such as fibrothorax or secondary infection.
