Pulmonary Sarcoidosis BAL Findings

A 34-year-old African-American woman presents with a 6-week history of dry cough, progressive dyspnea on exertion, low-grade fever, weight loss, erythema nodosum, and anterior uveitis. Chest imaging shows bilateral hilar lymphadenopathy with reticulonodular opacities. Serum ACE is elevated, and hypercalcemia is present. Fiberoptic bronchoscopy with bronchoalveolar lavage (BAL) is performed. The BAL findings marked **B** in the diagram—showing lymphocytic alveolitis with an elevated CD4:CD8 ratio of 5.8 (>3.5:1) and transbronchial biopsy demonstrating non-caseating epithelioid granulomas—are most consistent with which diagnosis?
