Vascular injury resulting in pseudoaneurysm formation in the plantar aspect of the foot is an uncommon injury after trauma. Such injuries are more often reported in the lateral plantar artery rather than the medial plantar artery, most likely because of its more superficial location. Traditional modalities in diagnosis have included ultrasound and digital subtraction angiography. We present a case of traumatic pseudoaneurysm of the lateral plantar artery following a foot laceration. Diagnosis was made by the use of high-resolution, time-resolved contrast-enhanced 3D magnetic resonance angiography, also referred to as "TRICKS" (time-resolved imaging of contrast kinetics). This technique provided high spatial resolution for the arterial anatomy as well as temporal resolution which allowed better delineation of the hemodynamic characteristics of the pseudoaneurysm.

足部足底出现假性动脉瘤是创伤后一种罕见的血管损伤。这种损伤在外侧足底动脉中比在内侧足底动脉中更为常见，很可能是因为它的位置更浅。传统的诊断方法包括超声和数字减影血管造影。我们报告了一例足部裂伤后外侧足底动脉外伤性假性动脉瘤。通过使用高分辨率、时间分辨对比增强 3D 磁共振血管造影术（也称为“TRICKS”）来诊断。该技术为动脉解剖结构提供了高空间分辨率和时间分辨率，从而更好地描绘了假性动脉瘤的血液动力学特征。
