This report documents the occurrence, diagnosis and treatment of a 29 year-old male patient who presented with progressive swelling of the left eye with associated progressive loss of vision, three months after sustaining a closed head injury in a road traffic accident. Magnetic resonance imaging (MRI) showed a large, ill-defined lesion in the left supraclinoid and paraclinoid region with variable contrast enhancement. A four vessel Digital Subtraction Angiography (DSA) showed a large, supra-clinoid pseudoaneurysm which had ruptured inferiorly into the roof of cavernous sinus, forming direct carotid cavernous fistula (CCF) which lead to dilatation of the superior ophthalmic vein and subsequent peri-orbital oedema and chemosis of conjunctiva. Complete obliteration of the indirect CCF was achieved by coiling of the aneurysm alone. During follow up, patient reported a significant improvement in vision and follow up DSA after one year shows no recurrence with this technique.

Treatment of Unruptured Large and Giant Carotid Cavernous Aneurysms in Japan at the Time of Flow Diverter Introduction: A Nationwide, Multicenter Survey by the Japanese Society on Surgery for Cerebral Stroke.

Background: Flow diverters (FDs) have been introduced for the management of large or giant cavernous carotid aneurysms (CCAs) in addition to conventional modalities, dramatically changing treatment strategies. The aim of this study was to examine the management of unruptured large/giant CCAs in Japan when FDs were being introduced using a nationwide survey.
Methods: 540 unruptured large/giant CCAs treated at neurosurgical teaching departments in Japan between 2012 and 2016 were retrospectively studied.

Purpose: To describe a case in which a right replaced posterior cerebral artery (PCA) was associated with an ipsilateral superior cerebellar artery (SCA) type persistent trigeminal artery (PTA) variant.
Methods: A 53-year-old man who had been diagnosed with chronic dissection of the left vertebral artery (VA) 4 months previously underwent follow-up magnetic resonance (MR) angiography using a 3-Tesla scanner.
Results: MR angiography showed a slightly dilated left VA at the terminal segment without interval change.

Purpose: We report a case of regression of a 2-year-old girl with bilateral primitive ophthalmic arteries (POAs).
Case Report: The patient presented with a headache and had no visual impairment or visual field abnormalities. Magnetic resonance angiography (MRA) revealed arteries originating bilaterally from the cavernous internal carotid artery segments, diagnosed as persistent POAs.

Petroclival approaches remain challenging given abundant cranial nerves and vessels. Common trajectories include transsphenoidal, transoral, middle fossa-extradural, and posterior through the cerebellar peduncle. We report a unique intra-axial, intradural approach to the petroclival and cavernous sinus.

Objective: Giant aneurysms of the cavernous segment of the internal carotid artery presenting as acute ischemic stroke (AIS) are rare and often misdiagnosed. Limited treatment experience further complicates management.
Case Presentation: A 70-year-old female presented with acute right middle cerebral artery (MCA) occlusion due to a dislodged thrombus from a giant internal carotid aneurysm.
