Axillary Anatomy and Pathology: Pearls and "Pitfalls" for Thoracic Imagers

J Thorac Imaging. 2022 May 1;37(3):W28-W40. doi: 10.1097/RTI.0000000000000639. Epub 2022 Feb 10.

Abstract

The axilla contains several important structures which exist in a relatively confined anatomic space between the neck, chest wall, and upper extremity. While neoplastic lymphadenopathy may be among the most common axillary conditions, many other processes may be encountered. For example, expanded use of axillary vessels for access routes for endovascular procedures will increase the need for radiologists to access vessel anatomy, patency, and complications that may arise. Knowledge of axillary anatomy and pathology will allow the imager to systematically evaluate the axillae using various imaging modalities.
