Non-indollar paraganglioma occurred in the head and neck, more common in the common carotid artery, jugular bulb and vagus nerve nodular ganglion site. About 0.012% of human tumors. There have been reports in the literature of individual cases of nasal cavity, larynx, trachea, lungs, mediastinum, eyelids, pineal gland and small intestine.
