which disease has 'cystic medial necrosis' as its histopathological feature?

Answer 1

Cystic medial necrosis (also referred to as cystic medial degeneration) is a disorder of large arteries.

In the aorta, this condition may lead to weakening of the artery, resulting in the formation of a fusiform aneurysm. There is also increased risk of aortic dissection.

There is an association between cystic medial necrosis and Marfan syndrome.

Answer 2

This article will give you an insight view, and will help you out:
Cystic medial necrosis:
Degenerative disease of the media of the aorta and other arteries with loss of elastic tissue and muscle cells. It is a pathological substrate for aortic dissection. It may also be manifested by proximal aortic ectasia or aneurysm. Cystic medial necrosis may occur as an isolated abnormality or as part of a systemic connective tissue disease such as Marfans syndrome or Ehlers Danlos syndrome. There is an increased risk of cystic medial degeneration and aortic or arterial dissection during pregnancy.
Similarly in Carotid artery is rare.
Hence limiting it to one disease is obscure.

Answer 3

aortic aneurysm
