zylindrische Bronchiektasen

Cylindrical bronchiectasis, also known as tubular bronchiectasis, is the most commonly identified morphologic type of bronchiectasis where there is smooth uniform enlargement of bronchi with loss of the normal distal tapering of the airways but without focal outpouchings or tortuosity.

For a general discussion, please refer to the article on bronchiectasis.
