A 41-year-old aerospace engineer presents with several months of progressive dyspnea, fatigue, and nonproductive cough. Vital signs show BP 128/82 mmHg, HR 92/min, RR 18/min, temperature 37.2°C, and SpO2 92% on room air. Chest CT reveals diffuse interstitial infiltrates and hilar lymphadenopathy. Serum calcium is elevated at 11.2 mg/dL. Lung biopsy demonstrates noncaseating granulomas. He denies fever or night sweats. Which of the following is the most likely diagnosis?
- A)Idiopathic pulmonary fibrosis
- B)Sarcoidosis
- C)BerylliosisGABARITO
- D)Hypersensitivity pneumonitis
- E)Tuberculosis
Explicação
Berylliosis is correct. Exposure in aerospace or electronics work with noncaseating granulomas and restrictive lung disease strongly suggests chronic beryllium disease. It can mimic sarcoidosis, but the occupational exposure is the key discriminator in this vi... Ver explicação completa e trilha adaptativa →
