A 71-year-old male with sarcoidosis was followed for 6 years without steroid therapy. He was admitted because of complete atrioventricular block. Chest X-ray showed hilar lymphadenopathy. Echocardiogram showed mild left ventricular hypertrophy without local wall thinning. Cardiac sarcoidosis was diagnosed by a defect of Thallium-201 (Tl-201) imaging and abnormal uptake of Gallium-67 (Ga-67). After the start of corticosteroid therapy, complete atrioventricular block was recovered. Abnormal uptake of Ga-67 was improved. Tl-201 and Ga-67 are useful to diagnose cardiac sarcoidosis, to evaluate the lesion of cardiac involvement and to estimate the efficacy of corticosteroid therapy.
一名71岁的结节病男性患者在未接受类固醇治疗的情况下随访了6年。他因完全性房室传导阻滞入院。胸部X线显示肺门淋巴结肿大。超声心动图显示左心室轻度肥厚，无局部室壁变薄。通过铊-201（Tl-201）显像缺损和镓-67（Ga-67）摄取异常诊断为心脏结节病。开始使用皮质类固醇治疗后，完全性房室传导阻滞恢复。Ga-67摄取异常得到改善。Tl-201和Ga-67有助于诊断心脏结节病、评估心脏受累病变以及评估皮质类固醇治疗的疗效。
