Thoracic CT demonstrated hilar and mediastinal lymphadenopathy. She underwent mediastinoscopic lymph node biopsy; biopsy result was consistent with noncaseating granuloma. Serum angiotensin converting enzyme level and muscle enzymes have been elevated. Muscular MRI and EMG findings were consistent with myositis. Muscle biopsy was done, and myopathy was found. The patient was diagnosed with sarcoidosis, L\u00f6fgren's syndrome, and sarcoid myopathy. The patient displayed remarkable clinical and radiological regression after 6-month corticosteroid and MTX therapy.<\/jats:p>","DOI":"10.1155\/2013\/125251","type":"journal-article","created":{"date-parts":[[2013,4,4]],"date-time":"2013-04-04T03:24:38Z","timestamp":1365045878000},"page":"1-3","source":"Crossref","is-referenced-by-count":1,"title":["Sarcoidosis
