pulsatile mass
Palpable swelling that expands and contracts with each heartbeat, suggesting arterial aneurysm or pseudoaneurysm.
Full Definition
A pulsatile mass is a physical finding characterized by a palpable enlargement that demonstrates rhythmic expansion and contraction synchronized with the cardiac cycle. This finding strongly suggests an arterial aneurysm, pseudoaneurysm, or arteriovenous communication. In vascular medicine, pulsatile masses require urgent evaluation to differentiate between true aneurysms and other vascular pathologies. The pulsatility distinguishes these lesions from venous masses or lymphadenopathy, and the finding should prompt immediate imaging to assess rupture risk and plan intervention.
Usage
Usage note: Always describe size, location, and quality of pulsation when documenting.
