概括

通过Tc-99m甲基二酸盐成像检测出一种罕见的骨肉瘤转移到膜的病例,尽管最初的远距离传播扫描结果是负面的. 这突出了成像模式.

科学领域:

在瘤学瘤学.
放射学放射学是一门学科.
整形外科手术整形外科手术

背景情况:

一名25岁的女性患有腿部低度骨骨肉瘤,接受了远端股骨置换.
最初的瘤监测,包括CT扫描,在手术后两年没有证据表明有远程转移.

研究的目的:

报告一种罕见的肺部肉瘤转移病例,通过骨透镜检测到患有骨肉瘤病史的患者.
讨论Tc-99m甲基二酸光学扫描在检测骨外骨肉瘤转移中的实用性和局限性.

主要方法:

进行Tc-99m甲二酸盐全身骨扫描和SPECT/CT,以调查假肢松动的症状.
得到了膜转移的组织病理学确认.

主要成果:

骨扫描和SPECT/CT检查显示了多发性肉瘤转移,尽管没有显示假肢松动.
在软组织和肺部吸收TC-99m甲二酸盐,虽然已知在骨髓瘤,很少在临床上观察到.

结论:

Tc-99m甲二酸盐光学扫描可以检测骨外骨质肉瘤转移,即使其他成像方法无法检测.
这一案例强调了考虑罕见病例的重要性,以及骨透镜在骨髓瘤患者综合性瘤监测中的潜在作用.

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
