Landmine detected in leg! Post-traumatic pseudoaneurysm of posterior tibial artery eroding bone.

Vascular injuries can initially present with hemorrhage or limb-threatening conditions, and may later lead to complications such as pseudoaneurysms or arteriovenous fistulas. Pseudoaneurysms are a known complication of arterial injuries resulting from trauma. Proper management following trauma is crucial in preventing pseudoaneurysm development. Here we report a case of pseudoaneurysm arising from an unnamed branch of posterior tibial artery eroding bone in a 4-year old boy who presented with a non-pulsatile, non-tender swelling on the medial aspect of left leg. Early identification of these complications is crucial for preserving the limb, as demonstrated by the patient's uneventful postoperative recovery.
