Cryptogenic bilateral fibrosing pleuritis is a rare condition, and its pathogenesis and clinical course are poorly understood, with no established therapy available. A 61-year-old man presented with bilateral pleural thickening and lymphocytic exudative effusions. The patient was diagnosed with fibrosing pleuritis with no evidence of a known etiology on a surgical pleural biopsy. Within 16 months from the onset of respiratory symptoms, restrictive ventilatory impairment progressed rapidly, resulting in hypercapnic respiratory failure requiring home oxygen and non-invasive positive pressure ventilation therapies.
