Distal upper extremity arterial aneurysms are rare with only a few case reports and small retrospective studies described. Most aneurysms are secondary to trauma making idiopathic aneurysms an especially rare disease process. An 83-year-old male presented with a painful pulsatile mass that was confirmed with ultrasound and computed tomography angiogram as a 2.0 × 1.5 cm radial artery aneurysm. He had successful aneurysm resection and primary repair. Histopathology confirmed a true aneurysm. This case report demonstrates successful excision and repair of this rare pathology. This case is been reported more for its rarity than complexity of the treatment.
