Introduction

Post-traumatic vascular injuries of the popliteal artery are uncommon and even rarer in its genicular branches.1 We present the state-of-art multi-detector CT angiography (MDCTA) findings of concomitant pseudoaneurysm and arteriovenous fistula (AVF) arising from the lateral superior geniculate artery (LSGA). The complexity of vascular anatomy and the variety of vascular injuries in the knee require detailed evaluation, which can be particularly challenging on non-invasive cross-sectional imaging. MDCTA, along with the multiplanar and colour coded 3D-volume rendered reconstructions, can be invaluable for surgical planning as demonstrated in our case whereby we could provide accurate information about the origin, course and drainage of AVF in addition to the evaluation of the associated pseudoaneurysm. To the best of the authors’ knowledge, there has been no previous literature demonstrating the state-of-art MDCTA imaging for both pseudoaneurysm and AVF in the LSGA.
