Abstract
BACKGROUND: Pseudoaneurysms are less common than true aneurysms. Herein, we present a rare case of a mass of the right posterior ascending artery. CASE DESCRIPTION: This was identified during routine dissection of an adult female cadaver. Histology demonstrated that the mass was a pseudoaneurysm. The mass was located posterior to the right alar ligament superior to the right portion of the transverse ligament and measured 7.37 mm and 2.97 mm. CONCLUSIONS: To our knowledge, such a case has not previously been reported. Epidural masses anterior to the cervical dura mater at the craniocervical junction should consider such a pathology in the differential diagnosis.
