Background: Pseudoaneurysm patients usually present months later following arterial injury with progressive swelling and pain at the initial site of injury. Quick intervention is needed to prevent complications such as thromboembolism, infection, rupture, neuropraxia and compartment syndrome. Case Report: A rare pseudoaneurysm of radial artery is being reported which was initially missed. A duplex scan confirmed the diagnosis with the patient undergoing a surgical repair of the vessel. Conclusion: Pseudoaneurysm of the forearm arteries is uncommon and ultrasound plays an important role in distinguishing vascular pathologies from other masses.
