Background: Aneurysms infra-patellar region are uncommon. Of them, true aneurysms are very rare and that of posterior tibial artery are extremely rare. The more common, pseudoaneurysms are commonly associated with trauma whereas the true ones are linked with either inflammatory or mycotic origins. Case Presentation: We reported another case of true aneurysm of posterior tibial artery without any evident aetiology. This was repaired with resection of aneurysm followed by interposition vein graft. Conclusion: Through this report, we discussed the rarity, review of literature and management of this unusual condition.
