Background: Aneurysms of the occipital artery (OA) are rare, with few cases published in the literature. The pathophysiology is unknown, and the presentation is variable. We present a case of a ruptured intracranial aneurysm arising from a branch of the OA. Case Description: A 36-year-old male with a history of ankylosing spondylitis presented with altered mental status after an assaulted. On examination, he was intubated, with a Glasgow coma scale of 9, and imaging of the head and neck revealed a subdural hematoma of the posterior fossa and the cervical spine. The patient underwent suboccipital craniectomy and C1-5 laminectomy with the evacuation of the subdural hematoma. Postoperative cerebral angiography showed an intracranial aneurysm arising from the retromastoid branch of the OA on the left side. Furthermore, the parent vessel of the aneurysm supplied the left lower half of the cerebellar hemisphere. The aneurysm and the parent vessel were embolized using platinum coils. The patient tolerated the procedure well, and magnetic resonance imaging of the brain showed a minor left-sided cerebellar infarct, which was asymptomatic. The patient was discharged home with a modified Rankin scale of 2. There were no outpatient follow-up data available because the patient lost to follow-up. Conclusion: Intracranial OA aneurysms are extremely rare with no clear consensus concerning the management of these aneurysms. They can be treated using endovascular and or open surgical techniques depending on the aneurysm characteristics, patient condition, rupture status, and others.

Introduction: Subdural hematoma without subarachnoid hemorrhage secondary to intracranial aneurysm rupture is rare and may complicate patient management due to delay in diagnosis and subsequent treatment. Herein, we describe a case presenting with pure SDH secondary to the rupture of a posterior communicating artery infundibular dilatation (PcoA-ID). To the best of our knowledge, this is the first case of rupture of a PcoA-ID with SDH in the convexity and tentorium, which also tracked into the upper cervical spine along the subdural space. Additionally, we briefly discuss the previously published cases of pure SDH secondary to intracranial aneurysm rupture. Case Report: A 44-year-old female presented with headache, dizziness, nausea and left-sided diplopia to an outside institution. Initial diagnostic work-up showed no intracranial hemorrhage, however, magnetic resonance angiography and subsequent digital subtraction angiography revealed left posterior communicating artery infundibular dilatation. Two days later, the patient presented with a loss of consciousness. Computed tomography was positive for bilateral hemispheric subdural hematoma with no evidence of subarachnoid hemorrhage. Digital subtraction angiography showed left posterior communicating artery infundibular dilatation and pseudoaneurysm originating from the inferior area of the infundibular dilatation, concerning recent rupture. Balloon assisted coil embolization was performed and the patient had a good outcome without any neurological deficit. Conclusion: Subdural hematoma in a young adult without a history of trauma or coagulopathy warrants additional vascular imaging to search for underlying vascular lesions. It should also be kept in mind that infundibular dilatation may rupture and cause a pure subdural hematoma.
