She noticed hoarseness in March 1989. Laryngeal biopsy failed to clarify the cause of hoarseness. Diagnosis of sarcoidosis was made in September by mediastinal lymph node biopsy. She developed chest pain in August 1990 and cardiovascular examinations were performed. However, there were no abnormalities in electrocardiography and echocardiography. In March 1992, corticosteroid therapy was started because of the enlargement of cardiac silhoutte. She developed frequent premature ventricular contractions and chronic heart failure and was hospitalized in July 1992. Severe left ventricular hypokinesia, marked decrease in LVEF and defect in 201 Thallium myocardial scintigraphy were shown. She was discharged in December after the iniation of digitalis, diuretic drugs, and antiarrhythmic drugs. She was hospitalized in July 1999 for severe heart failure and died in August. The autopsy revealed noncaseating epithelioid cell granulomas in mediastinal lymph nodes. In the heart muscle, fibrosis and granulomatous changes were observed. keywords ; Cardiac sarcoidosis, Heart failure, Hoarseness 1) 横浜船員保険病院内科 2) 横浜市立大学医学部附属病院医療情報部 3) 同中央検査部 4) 同第 1 病理学教室著者連絡先 : 川井孝子横浜船員保険病院 240-8585 横浜市保土ヶ谷区釜台町 43-1 TEL 045-331-1251 FAX 045-331-0864 1) Yokohama Seamen s Insurance Hospital, Department of Internal Medicine 2) Yokohama City University Hospital, Department of Medical Informatics 3) Yokohama City University Hospital, Department of Laboratory Medicine 4) Yokohama City University Hospital, First Department of Pathology 45
