Breast Pseudoaneurysm Following a Motor Vehicle Collision

Area of Science:

• Vascular Surgery
• Trauma Surgery
• Radiology

Background:

• Breast pseudoaneurysms (PSAs) are uncommon, typically arising after surgical or interventional procedures.
• PSAs following blunt breast trauma are exceptionally rare in medical literature.
• Prompt diagnosis and management are crucial for preventing complications.

Observation:

• A 67-year-old female presented with a right breast PSA after a motor vehicle collision.
• The patient had no history of recent breast procedures, with blunt trauma being the sole preceding event.
• Clinical presentation included a pulsatile mass in the affected breast.

Findings:

• The breast pseudoaneurysm was successfully managed non-operatively with a simple external pressure dressing.
• Follow-up imaging revealed spontaneous thrombosis of the pseudoaneurysm, indicating complete resolution.
• This case underscores the potential for non-traumatic PSAs to resolve without intervention.

Implications:

• Breast pseudoaneurysms should be considered in the differential diagnosis for patients with pulsatile breast masses or injuries, particularly after trauma.
• The possibility of spontaneous resolution suggests that conservative management may be appropriate in select cases.
• Increased awareness can improve the diagnosis and management of this rare but significant complication.
