Brachial artery pseudoaneurysms (PSA) are considered uncommon, but they can be limb and life threatening. Most etiologies are related to iatrogenic injury or following a fracture. Here we present a 37-year-old male complaining of a large swelling in his right upper arm that was gradually increasing in size for the last 7 months. It started with a sudden onset of pain while lifting heavy boxes at his daily job. Ultrasound and MRA showed a pseudoaneurysm of the right brachial artery. Resection of the PSA was performed with a vein interposition graft. This case illustrates the significance of considering PSA as a differential diagnosis in patients presenting with upper arm swelling without history of obvious trauma. •Brachial artery pseudoaneurysms are rare.•There are various possible underlying etiologies.•We report a pseudoaneurysm with gradual onset and course over seven months.•We illustrate the need to consider pseudoaneurysms in the differential diagnosis in in patients without history of trauma.•Patient was released after surgery without complications.
