Traumatic pseudoaneurysm of the superficial left palmar arch: A case report

Abstract

Pseudoaneurysms in the hands are rare entities, with only a few reported cases in English literature. The majority of these lesions arise from penetrating trauma, previous surgery, or artery puncture. Pseudoaneurysms are frequently missed, hence a strong clinical suspicion is required to make the correct diagnosis in a timely manner. We present a case of traumatic pseudoaneurysm of the superficial palmar arch in a 17-year-old CP child following a fall. The patient had a delayed presentation and was initially misdiagnosed as having a palmar abscess. We performed an ultrasound and CT angiogram to confirm the diagnosis of a superficial palmar arch pseudoaneurysm. We treated the patient surgically, and the wound healed uneventfully. Pseudoaneurysms should be included in the differential diagnosis of palmar masses.
