Paragangliomas are uncommon and those arising from the vagal trunk are rarer. Pigmented extra-adrenal paragangliomas are still rarer and reported sites of occurrence are the uterus, spine, retroperitoneum, bladder, mediastinum and orbit. The presence of abundant pigment in a cervical paraganglion has not been reported previously. We report one such unusual case of pigmented vagal paraganglioma that arose from the vagal trunk below the nodose ganglion, had massive central necrosis and showed hypovascularity on angiography. The unusual features and difficulties in the diagnosis of such cases are discussed.
副神经节瘤并不常见，起源于迷走神经干的则更为罕见。色素沉着型肾上腺外副神经节瘤更为罕见，报道的发生部位有子宫、脊柱、腹膜后、膀胱、纵隔和眼眶。此前尚未有关于颈副神经节中存在大量色素的报道。我们报告了一例如此罕见的色素沉着型迷走神经副神经节瘤病例，该肿瘤起源于结状神经节下方的迷走神经干，有大片中央坏死，血管造影显示血管减少。本文讨论了此类病例的异常特征及诊断难点。
