Abstract
We have encountered 2 cases of parathyroid adenomas that are atypical because of their large size, cystic character, and faint enhancement compared with the typical solid parathyroid adenomas. Specifically, the enhancement pattern of a typical parathyroid adenoma in a multiphasic scan demonstrates rapid arterial enhancement and rapid washout on delayed imaging, whereas, comparatively, the 2 cystic parathyroid adenomas we encountered demonstrated less arterial phase enhancement and little washout on venous and delayed-phase imaging.
摘要
我们遇到了 2 例甲状旁腺腺瘤，由于其体积较大、囊性特征以及与典型实性甲状旁腺腺瘤相比增强程度较弱，这些腺瘤不太典型。具体来说，多期扫描中典型甲状旁腺腺瘤的增强模式表现为动脉期快速增强，延迟期迅速廓清，而我们遇到的 2 例囊性甲状旁腺腺瘤则表现为动脉期增强程度较低，静脉期和延迟期廓清也较少。
