Paragangliomas or chemodectomas are neoplasms that arise from neural crest cells and histologically resemble their adrenal counterpart, the pheochromocytoma. Seventy-one percent of the extra-adrenal paragangliomas are located in the superior or inferior para-aortic area. This tumor usually presents as an abdominal mass producing back pain. Tumor localization has improved remarkably through the use of computed tomography and I131MIBG (metaiodobenzylguanidine) scintigraphy, particularly when tumors are hormonally active. Surgical excision remains the mainstay of treatment, although vascularity can at times make excision difficult.
副神经节瘤或化学感受器瘤是起源于神经嵴细胞的肿瘤，组织学上类似于其肾上腺对应物嗜铬细胞瘤。71%的肾上腺外副神经节瘤位于主动脉旁上区或下区。该肿瘤通常表现为引起背痛的腹部肿块。通过使用计算机断层扫描和I131MIBG（间碘苄胍）闪烁显像，肿瘤定位有了显著改善，尤其是当肿瘤具有激素活性时。手术切除仍然是主要的治疗方法，尽管血管丰富有时会使切除变得困难。
