Multimodal imaging follow-up of a left main trunk pseudoaneurysm presenting with cardiopulmonary arrest

This case highlights a rare occurrence of spontaneous LMT PsA in a patient with active MRSA infection. Although surgical resection is generally preferred, conservative management may be appropriate in selected high-risk patients. Multimodal imaging-including initial coronary angiography and intravascular ultrasound, serial CT for size monitoring, and follow-up angiography at recurrence-played a central role in anatomical assessment and therapeutic decision-making. Careful longitudinal evaluation with appropriate imaging tools is essential for safe and individualized management in such complex scenarios.
