The (131)I-iodide ((131)I) whole-body scan, for thyroid carcinoma is at times difficult to interpret. In a diagnostic whole body (131)I scan of a patient with follicular carcinoma, a posterior skull lesion was partially hidden by overlapping facial structures. On lateral head view, the abnormality was clearly evident. SPECT/CT and MRI showed the lesion originated in the occipital bone and had enlarged into the posterior fossa. The mass was surgically removed and the patient received (131)I therapy for residual tissue. The study demonstrates a pitfall in the reading of two dimensional radioiodine images which can be overcome by SPECT or lateral imaging.
用于甲状腺癌的碘-131（¹³¹I）全身扫描有时难以解读。在一名滤泡状癌患者的诊断性¹³¹I全身扫描中，后颅骨病变部分被重叠的面部结构遮挡。在头部侧位视图中，异常清晰可见。单光子发射计算机断层扫描/计算机断层扫描（SPECT/CT）和磁共振成像（MRI）显示病变起源于枕骨并已扩展至后颅窝。该肿块被手术切除，患者接受了¹³¹I治疗以处理残留组织。这项研究表明在二维放射性碘图像解读中存在一个陷阱，而通过SPECT或侧位成像可以克服这一陷阱。
