syphilitic aneurysm
manifestation of 3o syphilis
thoracic aorta, arch
caused by obliterative endarteritis in vasa vasorum
Grossly
dilation of the aortic root
ding-dong: looks like tree bark from continual scarring and healing
Histology
wall is invaded by inflammatory cells
micrograph of spirochetes
Pathology
gross: massive dilatation of aorta and tree-barking
micro: vasa vasorum are surrounded by inflammatory cells
Clinical features
pretty rare in the US today because syphilis doesn’t often get to the tertiary stage
involvement of the aortic root causes aortic insufficiency
large size leads to respiratory and swallowing difficulties, cough, and pain
