Background: Carotid artery dissections (CADs) are a relatively rare disorder, whereas intracranial aneurysms (IAs) form a common cerebrovascular pathology. Since both vascular entities share similar risk factors and associations with connective tissue and vascular disorders, a common pathogenesis has been suggested. Here, we present a case of the concomitant occurrence of a CAD and a ruptured basilar trunk aneurysm (BTA). In the discussion, we elaborate on both vascular entities and have reviewed the literature on their concomitant incidence and potential shared pathogenesis. Case Description: We present a case of a 40-year-old female patient who was admitted to our hospital because of subarachnoid hemorrhage following a minor head trauma. Imaging revealed a BTA and unilateral extracranial dissection of the internal carotid artery. Despite coiling of the aneurysm, stenting of the dissection, and antithrombotic therapy, the patient died due to extensive cerebral ischemia sequelae. Conclusion: CAD and BTAs have both been associated with a vascular vulnerability but their concomitant occurrence has not been described previously. The previous studies have suggested an increased incidence of IAs in patients with a CAD and vice versa. However, the number of studies and reports on this mutual increased incidence is limited. Therefore, a shared pathogenesis seems rather speculative. In our case, we suggest that a posttraumatic CAD-induced hemodynamic alterations resulting in rupture of the saccular BTA.
