Formation of a large fusiform aneurysm next to a medullary infarction due to posterior inferior cerebellar artery dissection
We report a 48-year-old male with Wallenberg syndrome due to PICA dissection, which was difficult to diagnose on first admission. He reported sudden-onset sensory disturbance on the right side of his face, ataxic gait, and headache. Brain magnetic resonance imaging (MRI) revealed a fresh cerebral infarct in the right lateral medulla oblongata. Serial MRI and magnetic resonance angiography (MRA) performed at the time of his admission failed to demonstrate cerebral vessel abnormalities. MRI study performed 18 months after the attack revealed a fusiform aneurysm on the lateral medullary segment of the PICA; its site was extre...

Elderly onset of MELAS in a male: A case report
ConclusionElderly onset of MELAS is rare and easily misdiagnosed as an ischemic stroke. MELAS with the onset of stroke-like episodes should be considered in adult or elderly patients with imaging findings that are atypical for cerebral infarction. The use of multimodal MRI in the clinical diagnosis of MELAS could be extremely beneficial.

Pharyngo-tympano-stapedial middle meningeal artery variant supply to a falcotentorial dural arteriovenous fistula
We report the case of a middle-aged patient with severe, daily headache who presented to our institution for angiography and treatment. CT angiography and MRI demonstrated an enlarged left middle meningeal artery coursing to a large venous varix in the falcotentorial region. Dural arteriovenous fistula was confirmed by subsequent cerebral angiography. Endovascular treatment was performed but without complete obliteration of the fistula. Follow-up angiography demonstrated parasitized arterial supply from a right middle meningeal artery arising from the proximal cervical internal carotid artery coursing through the middle ea...

Case report: Acute ischemic stroke caused by intracranial artery dissection in a patient with skull fractures
We report a 53-year-old man fell to develop blunt cerebrovascular injuries (BCVIs) more than 2 months ago. During his rehabilitation, he often had a transient left headache and underwent short-term right limb weakness twice, but he did not care. He was hospitalized again because of suffering right limb weakness for more than 4 h. The brain computed tomography angiography (CTA) showed subtotal occlusion of the left middle cerebral artery M1 segment, and the vascular morphology displayed the IAD. The patient was then treated with balloon dilation and a self-expanding stent. This case highlights that IAD may show delayed onse...

Neurosarcoidosis Presenting with Prominent Periventricular White-Matter Lesions during Steroid Treatment for Autoimmune Hepatitis
A 63-year-old woman under treatment of autoimmune hepatitis presented with headache, memory loss, and somnolence. Three months before admission, the patient experienced liver inflammation relapse after prednisolone (PSL) cessation. Consequently, PSL was resumed and then tapered. Cerebrospinal fluid (CSF) examination showed lymphocytic pleocytosis with remarkably reduced glucose and elevated angiotensin-converting enzyme and soluble interleukin-2 receptor levels. Magnetic resonance imaging (MRI) revealed prominent bilateral periventricular white-matter lesions, hydrocephalus, ischemic stroke with gadolinium enhancement of f...

A Case of Giant Cell Arteritis Presenting As Catastrophic Posterior Circulation Stroke: A Diagnostic Dilemma
We describe a case of a 75-year-old woman who presented with jaw claudication and temporal headache. A colour duplex ultrasonography and later biopsy of the temporal arteries confirmed GCA and she was commenced on oral steroids. She was subsequently readmitted with a new worsening vision of both eyes and confusion. Her brain images revealed acute bilateral vertebral artery thrombus with haemorrhagic transformation. She was loaded on intravenous steroids. The next day she developed vomiting, bilateral visual loss and a cardiac arrest from ventricular fibrillation. Following the return of spontaneous circulation, she was tak...

E-074 Case report: reconstructive endovascular treatment of symptomatic long segment dissection with pseudo-aneurysm of dominant left vertebral artery
We report a case of 27 year old Caucasian female with no known medical history who presented to our hospital with several days’ history of posterior headache and neck pain. CT head was unremarkable. CTA head and neck showed short segment of severe stenosis secondary to dissection at the V2-V3 junction of dominant left vertebral artery with associated 6 mm pseudo aneurysm. Right vertebral artery was hypoplastic and it ended in PICA. The dissection was presumed to be spontaneous as patient denied any trauma or strenuous neck manipulation or family history of connective tissue disorders. She was started on antiplatelet ...
