A case of nonfunctional struma ovarii preoperatively diagnosed by scintigraphy of the pelvis using I-123 NaI is reported. US, CT, and MRI revealed a multilobulated mass composed of cystic and solid components. CT showed cystic components with slightly high density and MRI showed various signal intensities on T1- and T2-weighted images. I-123-scintigraphy of the pelvis showed uptake in the pelvic mass. Microscopic examination revealed the histologic appearance of thyroid tissue accompanied by follicular adenoma. I-123 scintigraphy of the pelvis was useful for reaching the correct preoperative diagnosis in this patient with nonfunctional struma ovarii.
报道了一例通过使用 I-123 碘化钠进行盆腔闪烁显像术前诊断出的无功能性卵巢甲状腺肿病例。超声、CT 和 MRI 显示一个由囊性和实性成分组成的多叶状肿块。CT 显示囊性成分密度略高，MRI 在 T1 和 T2 加权图像上显示出各种信号强度。盆腔 I-123 闪烁显像显示盆腔肿块有摄取。显微镜检查显示甲状腺组织伴有滤泡性腺瘤的组织学表现。盆腔 I-123 闪烁显像有助于对该例无功能性卵巢甲状腺肿患者做出正确的术前诊断。
