Two cases of carotid glomus chemodectomas with production of catecholamines are reported. The place of chemodectomas among the neuroendocrine tumors called paragangliomas is recalled. Chemodectomas only very infrequently produce catecholamines (1 to 10%). Magnetic resonance imaging is superior to computerized tomography and metaiodobeuzylguanidine scintigraphy in the detection and the characterization of adrenal and extra-adrenal functioning paragangliomas of the orthosympathic system. Few data are available for the imaging of functioning parasympathetic paragangliomas (chemodectomas). The two case reports illustrate the contribution of the magnetic resonance imaging in the detection and the characterization of chemodectomas.
报告了两例产生儿茶酚胺的颈动脉体化学感受器瘤。回顾了化学感受器瘤在称为副神经节瘤的神经内分泌肿瘤中的位置。化学感受器瘤极少产生儿茶酚胺（1%至10%）。在检测和表征正交感神经系统的肾上腺和肾上腺外功能性副神经节瘤方面，磁共振成像优于计算机断层扫描和间碘苄胍闪烁显像。关于功能性副交感神经节瘤（化学感受器瘤）成像的资料很少。这两个病例报告说明了磁共振成像在检测和表征化学感受器瘤中的作用。
