Pseudoaneurysms arise from a disruption of arterial wall continuity resulting from inflammation, trauma, or various iatrogenic causes. Pseudoaneurysms may progress with complications such us infection, local compression on neurovascular structures or rupture. In drug users, pseudoaneurysm is often due to traumatic effects of needles on vascular wall. Conventional angiography remains the standard of reference for an invasive diagnosis of arterial integrity in patients with extremity trauma, but noninvasive diagnostic modalities should be included in the initial work-up, such as Doppler ultrasound and computed tomography. We report a case of bilateral metachronous humeral artery pseudoaneurysm with severe acute infectious of the right one, correctly diagnosed by computed tomography angiography (CTA) imaging and conventional angiography in a 37-year-old intravenous-drug-abusing female. She presented to the emergency room with a two-day history of an enlarging painful right forearm and ulcerated mass on the volar-side of her elbow. On the controlateral elbow a smaller pulsating but not ulcerated mass was found. In our case, the patient came to the emergency department with metachronous bilateral humeral artery pseudoaneurysm with one-side acute infectious complication because of a misdiagnosis performed two days before, when, in the same department, a clinician tried to aspirate it, wrongly supposing an abscess. A review of pseudoaneurysm imaging features and optional treatments is discussed.
