at autopsy, the thoracic aorta of a 73 - year - old male has a dilated root and arch, giving the intimal surface a \tree bark\ appearance. microscopically, the aorta shows an obliterative endarteritis of the vasa vasorum. which of the following laboratory test findings is most likely to be found recorded in this patients medical record?
high double - stranded dna titer
antibodies against treponema pallidum
4+ ketonuria
sedimentation rate of 105 mm/h

Explanation:

The patient has syphilitic aortitis, which is characterized by "tree - bark" appearance of the aorta and obliterative endarteritis of the vasa vasorum. Syphilis is caused by Treponema pallidum, and antibodies against Treponema pallidum are found in syphilis. High double - stranded DNA titer is associated with systemic lupus erythematosus. 4+ ketonuria is seen in diabetic ketoacidosis. A sedimentation rate of 105 mm/h is a non - specific indicator of inflammation.

Answer:

Antibodies against Treponema pallidum
