[A case of sarcoidosis with primary acute pulmonary cavitation].
A 23-year-old man was admitted to our hospital on June 24, 1991, because of worsening chest X-ray findings of sarcoidosis. In August 1990, he was referred to our outpatient office, because of BHL and nodular lesions on chest X-ray film performed at his company 4 months earlier. At that time, serum ACE was elevated to 34.0 IU/l, and Ga scintigraphy showed abnormal uptake in bilateral lacrimal and salivary glands, mediastinal and hilar lymph nodes, and in the lung fields. TBLB specimen showed noncaseating epithelioid granuloma with giant cells and negative stains for acid-fast bacilli. Although it was planned to follow this patient without medication, he did not return to our outpatient department. In June 1991, because of worsening of lesions in the lung at annual checkup at his company, he was referred and admitted for steroid therapy. Chest X-ray film on admission showed BHL, multiple nodular lesions in both lung fields, and bullous change in the left upper lobe. Chest CT on admission showed three cavitating lesions within preexisting nodules. PPD skin test was negative, and sputum smears and cultures were repeatedly negative for pyogenic bacteria and acid-fast bacilli. Therapy was initiated with prednisolone 30 mg daily. Four months later, there was marked resolution of BHL and nodular lesions, and the cavitating lesions were no longer visible on chest X-ray film. From the clinical and radiological observations, it is concluded that the cavitating lesions in the present case were primary acute pulmonary cavitation in sarcoidosis, distinct from infection, bullae, or cystic bronchiectasis which are seen in the chronic and fibrotic stages of sarcoidosis.
