Ga-67 scintigraphy is helpful in the assessment of active extrapulmonary sarcoidosis. Muscular involvement of sarcoidosis is often asymptomatic or nonspecific, and laboratory examinations do not provide convincing evidence of muscular involvement. The authors report a case of muscular sarcoidosis detected by Ga-67 scintigraphy. In a patient who had fever and arthralgia of both knee joints, Ga-67 scintigraphy showed mediastinal and hilar involvement of sarcoidosis with unexpected extensive muscular uptake. Magnetic resonance imaging revealed in detail intramuscular infiltration of sarcoid granuloma. Ga-67 scintigraphy is useful in detecting inflammatory muscular involvement of sarcoidosis and other multiorgan involvement.
镓-67闪烁扫描术有助于评估肺外结节病的活动情况。结节病的肌肉受累通常无症状或不具特异性,实验室检查也无法提供肌肉受累的确切证据。作者报告了一例通过镓-67闪烁扫描术检测出的肌肉结节病病例。在一名出现发热及双膝关节疼痛的患者中,镓-67闪烁扫描术显示结节病累及纵隔和肺门,同时意外出现广泛的肌肉摄取。磁共振成像详细显示了结节性肉芽肿的肌内浸润。镓-67闪烁扫描术对于检测结节病的炎症性肌肉受累及其他多器官受累很有用。
