Rapid development of 9 cerebral aneurysms in varicella-zoster virus vasculopathy
A patient with zoster in multiple dermatomes, severe headache, and normal magnetic resonance angiography (MRA) and 4-vessel digital subtraction angiogram (DSA) developed 9 anterior circulation aneurysms 2 months later. Antiviral treatment resulted in clinical improvement, size reduction of most aneurysms, and complete resolution of the 2 largest aneurysms.

Reversible cerebral vasoconstriction syndrome following carotid stenting
A 60-year-old woman on venlafaxine presented with headache and left-sided weakness 1 month after undergoing right common carotid artery stenting. Catheter-based angiogram identified new irregularities of the right anterior cerebral and right middle cerebral artery (figure, A–C). Investigations for vasculitis, including CSF studies, were unremarkable. The vessel irregularities and symptoms improved after administration of intra-arterial verapamil (figure, D–F). Unilateral reversible cerebral vasoconstriction syndrome has previously been described after carotid endarterectomy. The mechanism is unclear; however, i...

Neurology in Africa
"Ex Africa semper aliquid novi [Out of Africa always something new]," wrote the Roman historian Pliny the elder. Neurology in Africa is no different, with the recent emergence of new diseases ranging from HIV to konzo. Historically, neurology in Africa has been included under the heading tropical neurology or neurology in the tropics and is well-reviewed by Poser and Poser.1 Some of the earliest descriptions of the more common neurologic disorders (ND), including stroke, migraine, paralysis, and seizures, come from ancient Egypt and Greece. These accounts include diseases like lathyrism, which occurs in temperate as well a...

Clinical Reasoning: A 42-year-old man who developed blurred vision and dropped his iPod while jogging
A 42-year-old man noted sudden onset of blurriness in his left eye and dropped his iPod from his right hand while jogging. In the emergency room, it was noted that visual blurring resolved with right eye closure, but his ophthalmologic examination was otherwise normal. He had subtle right nasolabial fold flattening and right arm pronator drift. His examination was otherwise normal. He reported no headache, neck pain, prior trauma, prior transient neurologic deficit, or palpitations. He took no medications and did not smoke, drink alcohol, or use illicit drugs.

Heterogeneity in neurologic education and care in Asian and Oceanian region
The Asian subcontinent and Oceania (comprising islands in the Pacific Ocean) are home to more than 60% of the world's population. The burden of neurologic disease and sickness is thereby high and medical care is in high demand. There are many developing countries with diverse cultural, economical, political, religious, and historical backgrounds within the Asian and Oceanian region.1,2 Recently, enhanced medical care in these developing countries has resulted in greater longevity, which has increased the burden on those providing health care. The prevalence of neurologic illness has also increased and has emerged as a prio...

Cerebrovascular regulation, exercise, and mild traumatic brain injury
A substantial number of people who sustain a mild traumatic brain injury report persistent symptoms. Most common among these symptoms are headache, dizziness, and cognitive difficulties. One possible contributor to sustained symptoms may be compromised cerebrovascular regulation. In addition to injury-related cerebrovascular dysfunction, it is possible that prolonged rest after mild traumatic brain injury leads to deconditioning that may induce physiologic changes in cerebral blood flow control that contributes to persistent symptoms in some people. There is some evidence that exercise training may reduce symptoms perhaps ...

Mystery Case: Cerebral amyloid angiopathy-related inflammation
A 59-year-old man was arrested for unruly public behavior. He was subsequently found unresponsive with bilateral upper extremity extensor posturing and lower extremity triple flexion when stimulated. Over the next 48 hours, he awoke and became belligerent. MRI revealed innumerable cortical microhemorrhages on susceptibility-weighted imaging (figure, A) and asymmetric subcortical T2 hyperintensities (figure, B) consistent with cerebral amyloid angiopathy–related inflammation (CAA-ri).1 With corticosteroid treatment, he rapidly became calm and conversant, returning to near his premorbid baseline with only mild residual...

Reduced trigeminovascular cyclicity in patients with menstrually related migraine
Conclusions: Our study provides evidence for a reduced menstrual cyclicity of both estradiol levels and the trigeminovascular vasodilator system in patients with MRM.

Clinical Reasoning: An unusual case of subacute encephalopathy
A 52-year-old previously healthy man presented with 8 months of progressive cognitive decline. He complained of months of confusion, fatigue, depression, hypersomnolence, headaches, and, subsequently, urinary incontinence and unsteady gait. His family reported that he spoke of his deceased mother as if she were alive. His executive deficits progressed, leading to termination of his employment and a motor vehicle accident. He was evaluated and treated in Morocco before presenting to our institution for further care.

Teaching NeuroImages: Cortical blindness following acute obstructive hydrocephalus by a colloid cyst
A 46-year-old woman was admitted for acute headache, postseizure confusion, and visual loss. Urgent head CT scan showed obstructive hydrocephalus due to a colloid cyst (figure 1). External ventricular drains inserted emergently demonstrated CSF under pressure, above 40 mm H2O. MRI confirmed the suspected diagnosis of a colloid cyst and highlighted bilateral occipital lobe infarcts (figure 2). CT angiography showed no thrombosis of the posterior cerebral arteries (PCAs). After neurosurgical excision of the colloid cyst, the patient remained blind. The presumed mechanism of infarction was acute compression of the PCAs agains...

Alexia with agraphia as a rare presentation of migraine (P1.309)
CONCLUSIONS:This represents the first-ever case report of alexia with agraphia presenting as migraine aura. The pathophysiology of cortical spreading depression within migraine auras easily supports cortical dysfunction of the angular gyrus preceding or during a migraine attack.Disclosure: Dr. Suhaib has nothing to disclose. Dr. Vaughn has received personal compensation for activities with various multiple sclerosis surveys.

Neuro-Behcet's Syndrome:Case Reports Emphasizing Challenges of Early Diagnosis (P2.075)
CONCLUSIONS: In both cases, NBS was ultimately diagnosed based on characteristic MRI findings, particularly fluctuating brain stem-diencephalic involvement, superimposed on supportive clinical and CSF profiles. Challenges to early diagnosis are highlighted by our cases and by the literature. The differential diagnosis is often broad at onset. Mucocutaenous symptoms can be a clue but may not be present. Awareness of NBS and its neuroimaging correlates is critical to enable timely diagnosis, particularly given that this condition can favorably respond to steroids and steroid-sparing agents.Disclosure: Dr. Feldman has nothing to disclose.
