We report a case of idiopathic hypertrophic cranial pachymeningitis in which a high accumulation of thallium-201 was observed on an early single-photon emission CT (SPECT) scan. The patient's symptoms initially improved with steroid therapy but recurred repeatedly. MR images failed to show any change with treatment; however, thallium-201 uptake correlated closely with the fluctuation of symptoms. 201Tl-SPECT was therefore useful in identifying inflammatory activity that was not detected by MR imaging.
我们报告一例特发性肥厚性硬脑膜炎病例,在早期单光子发射计算机断层扫描(SPECT)中观察到铊-201高度积聚。患者症状最初经类固醇治疗有所改善,但反复复发。磁共振成像(MR)图像显示治疗后无任何变化;然而,铊-201摄取与症状波动密切相关。因此,201Tl-SPECT有助于识别磁共振成像未检测到的炎症活动。
