Pancoast sydrome 肺尖腫瘤症候群
1.also called a pulmonary sulcus tumor or superior sulcus tumor, is a tumor of the pulmonary apex.
2.Most Pancoast tumors are non-small cell cancers.
3.The growing tumor can cause compression of a brachiocephalic vein, subclavian artery, phrenic nerve, recurrent laryngeal nerve, vagus nerve, or, characteristically, compression of a sympathetic ganglion resulting in a range of symptoms known as Horner's syndrome.
4.when the brachial plexus roots are involved it will produce Pancoast syndrome;
involvement of sympathetic fibres as they exit the cord at T1 and ascend to the superior cervical ganglion will produce Horner's syndrome. (M.A.P)
