ABSTRACT
Scalp pseudoaneurysms occur most commonly because of trauma and are often in the superficial temporal artery due to the lack of soft tissue coverage between skin and bone, making it more vulnerable anatomically.1,2 Pseudoaneurysms of the occipital artery (OA) also occur but are extremely rare.2-4 An 80-year-old man presented with scalp bleeding and a small left-sided posterior scalp laceration after a fall and head strike 10 days prior. He was admitted and during his 2-week hospital stay, the occipital laceration continued to rebleed (Video 1). He developed a 2-cm pulsatile ulcerative mass with central necrosis on the left nuchal ridge. Computed tomography angiography revealed an ovoid left occipital lesion measuring 1.3 × 2.5 × 2.3 cm with delayed contrast filling and partial thrombosis. The base of the lesion had dense contrast filling continuous with the OA, diagnostic of OA pseudoaneurysm. OA pseudoaneurysm may be treated endovascularly or surgically. While surgical resection is the most common treatment, minimally invasive techniques have been successfully done through direct injection of N-butyl cyanoacrylate or endovascular embolization. The clinical presentation of this case was unique because this patient had an ulcerated lesion with central necrosis overlying the pseudoaneurysm. Endovascular management alone would not address the open lesion, which is at high risk for infection. The risk of infection would increase after embolization of the occipital artery, causing further necrosis of the tissue.
