Abstract

Retrosternal goiter is one of the common causes of anterior mediastinal masses. Scintigraphic diagnosis of retrosternal goiter plays an important role in avoiding invasive diagnostic procedures, and SPECT acquisition may enhance the diagnostic sensitivity of this technique as compared with planar scintigraphy. Here, I report a case of retrosternal goiter that was demonstrated on SPECT/CT obtained with Tc pertechnetate, but not on planar scintigraphy with the same tracer.

摘要

胸骨后甲状腺肿是前纵隔肿块的常见原因之一。放射性核素显像诊断胸骨后甲状腺肿对于避免有创性诊断程序具有重要作用，与平面闪烁显像相比，SPECT 采集可能会提高该技术的诊断灵敏度。在此，我报告了一例 Tc 高锝酸盐 SPECT/CT 显示但平面闪烁显像不显示的胸骨后甲状腺肿病例。
