OBJECTIVE
The imaging features of intrapericardial paragangliomas (pheochromocytomas) are described.
MATERIALS AND METHODS
We conducted a retrospective study of the imaging features of all intrapericardial paragangliomas seen at our institution over the last 13 years.
RESULTS
In this study, intrapericardial paragangliomas were typically located adjacent to or involved the left atrium. The diameter of the tumors ranged from 3 to 8 cm. Metaiodobenzylguanidine (MIBG) scintigraphy revealed 11 of 12 tumors (sensitivity = 92%). After MIBG scintigraphic location, dynamic contrast-enhanced CT revealed all 12 tumors.
CONCLUSION
Intrapericardial paragangliomas are rare tumors, typically located adjacent to or involving the left atrium. For initial detection, regional location of these extraadrenal tumors, and detection of distant metastases, MIBG scintigraphy is recommended. Dynamic contrast-enhanced CT or MR imaging can then provide detailed anatomic delineation before surgical resection.
目的
描述心包内副神经节瘤（嗜铬细胞瘤）的影像学特征。
材料与方法
我们对本机构过去13年中所见的所有心包内副神经节瘤的影像学特征进行了回顾性研究。
结果
在本研究中，心包内副神经节瘤通常位于左心房附近或累及左心房。肿瘤直径为3至8厘米。间碘苄胍（MIBG）闪烁扫描显示12个肿瘤中的11个（敏感性=92%）。在MIBG闪烁扫描定位后，动态对比增强CT显示了所有12个肿瘤。
结论
心包内副神经节瘤是罕见肿瘤，通常位于左心房附近或累及左心房。对于这些肾上腺外肿瘤的初步检测、区域定位以及远处转移的检测，建议采用MIBG闪烁扫描。然后，动态对比增强CT或磁共振成像可以在手术切除前提供详细的解剖学描绘。
