Case Session 05: Systemic and Inflammatory Disease (2018)-Serial CMR Follow Up of Left Ventricular Pseudoaneurysm and Aneurysm In a Child With May-Thurner Syndrome.

Serial CMR Follow Up of Left Ventricular Pseudoaneurysm and Aneurysm In a Child With May-Thurner Syndrome.

Video Transcription

Video Summary

A 4-year-old boy developed MSSA sepsis with DVT due to May-Thurner syndrome, causing septic emboli, multi-organ infarcts, shock, pericardial effusion, and brain hemorrhagic lesions. Imaging later showed a small LV pseudoaneurysm and a separate aneurysm, both stable on follow-up CMR. CMR was key for distinguishing pseudoaneurysm from aneurysm using wall motion and delayed enhancement patterns. He improved with six weeks of antibiotics, anticoagulation, and supportive care, and was discharged ambulatory without neurologic or cardiac sequelae. The case highlights an unusual complication of May-Thurner syndrome and the diagnostic value of cardiac MRI in pediatric post-infectious ventricular outpouchings.
