A 40-year-old man is noted to have miosis of the right eye and ipsilateral
ptosis. He reports that he has noted that this side of his face is not
sweating when he is working recently. The most cause of this clinical picture
may be
a. Pancoast tumor
b. Brainstem CVA
c. Dissection of the carotid artery
d. Idiopathic

d is the right ans....this was tricky guys...

Although all of these processes may cause Horner™s syndrome, the most
common cause remains idiopathic. The Pancoast tumor and dissection of
the carotid impinge on the sympathetic nerves, thus exerting their effect.
Brainstem strokes would work at the central level to interrupt the sympathetic
nerves.
