Question 8 in “Clinical Quiz” (November 1, 2000, page 1958), pertaining to the article “Acute Brachial Plexus Neuritis: An Uncommon Cause of Shoulder Pain,” was unclear. The best answer for Question 8 is A; osteophytes are present on radiographic studies. Because it is possible to have a radiculopathy involving multiple root levels, B is a possible correct answer, but it would not be the best response because the situation is extremely unusual. The question is printed below; the correct answer is A.
