Pseudoaneurysms rarely occur in peripheral arteries beyond the lower leg. Herein, we report a case of tibial nerve palsy due to the compression of a pseudoaneurysm of the posterior tibial artery caused by trauma. The patient was a 34-year-old man who suffered a puncture wound from glass in the right Achilles tendon area. There was no pulsatile bleeding, and the glass fragment was removed without any problems; however, the patient experienced pain and difficulty walking on day 12 of the injury. It took time to determine the cause, but a pseudoaneurysm was identified on contrast-enhanced computed tomography. We resected the pseudoaneurysm, thereby resulting in symptomatic improvement. In cases presenting with delayed onset of neurological symptoms following an injury, an aneurysm in the accompanying artery should be considered as a possible cause.
