Pseudotumoral presentation of cerebral amyloid angiopathy-related inflammation
Conclusion: The identification of one or several nonenhancing space-occupying lesions, especially in elderly patients presenting with cognitive impairment, should raise suspicion for the pseudotumoral presentation of CAA-I and lead to T2*-GRE sequences. Perfusion MRI and MRS appear to be useful techniques for the differential diagnosis of this entity.

Pearls & Oy-sters: Spontaneous intracranial hypotension and posterior reversible encephalopathy syndrome
A 65-year-old woman with no significant medical history was brought to the emergency room after experiencing 2 weeks of band-like occipital headaches and 2 days of progressive mental status changes. Her neurologic examination was significant for decreased alertness, disorientation to time, confabulation, loss of recent and remote memory, diffuse hyperreflexia, and a left Hoffmann sign. MRI of the brain with contrast showed bilateral subdural hygromas, diffuse enhancement of the dura mater, with mild sagging of the brainstem suggestive of intracranial hypotension (figure 1, A and B). MRI of the spine showed a large collecti...

Bilateral occipital strokes from an atherosclerotic trigeminal artery
A 58-year-old man with coronary disease presented with headache, confusion, and vision loss. On examination, he had retrograde and anterograde amnesia, superior homonymous quadrantanopias, and could not identify colors. MRI showed bilateral occipital infarcts involving the parahippocampal and lingual gyri (figure 1). CT angiography revealed a hypoplastic vertebrobasilar circulation, with a persistent right trigeminal artery supplying the rostral basilar artery (figure 2). Persistent fetal arteries may increase risk of atherogenesis due to increased turbulence.1 A rare cortical syndrome, new-onset achromatopsia with amnesia...

Long-term use of daily sumatriptan injections in severe drug-resistant chronic cluster headache
Chronic cluster headache (CCH) is a rare but severely debilitating condition.1 Some patients have drug-resistant CCH and continue to have daily attacks using abortive agents for long periods many times per day, mainly subcutaneous sumatriptan (SS).2 According to pharmaceutical company indications, the maximum SS dosage is 2 injections (12 mg) per day but these patients often use more. This limitation appears reasonable because of single case reports of cardiac arrest attributable to SS vasoconstrictive properties.3,4 Usually these events occur at the initial administration, and an underlying occult coronary artery disease ...

Cerebral hyperperfusion on arterial spin labeling MRI during CADASIL migrainous encephalopathy
Migrainous encephalopathy is a rare and poorly understood manifestation of the inherited vasculopathy cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). Patients may present with migraine with aura, complicated by confusion, fever, and decreased conscious level.1 In this case, a patient with migrainous encephalopathy underwent cerebral perfusion imaging with arterial spin labeling (ASL) MRI before, during, and following admission.

Migraine makes the stroke grow faster?
Long associated with increased incidence of stroke,1,2 migraine has been linked with mechanisms involving the vasculature (vasospasm, arterial dissection, endothelial dysfunction, venous thrombosis), heart (patent foramen ovale), and blood (hypercoagulability).3 Since cerebral ischemia can induce cortical spreading depression, the physiologic process underlying aura, migraine with aura may theoretically represent a TIA equivalent in a subset of people. In addition to the heightened occurrence of stroke in migraineurs, a growing body of evidence suggests more dire consequences when stroke occurs, with experiments in mice wi...

Sensitivity to acute cerebral ischemic injury in migraineurs: A retrospective case-control study
Conclusions: This case-control study supports the hypothesis that a history of migraine, particularly with aura, is associated with a no-mismatch pattern during acute ischemic stroke, consistent with data obtained in migraine mutant mice.

Clinical Reasoning: A 50-year-old man with "elephantiasis" and headache
A 50-year-old man with a medical history of "elephantiasis" of the legs, status post left above the knee amputation with prosthetic limb, and hypothyroidism presented with 1 week of headache and nausea. The headache was continuous, with gradual worsening over the 7 days prior to admission, and he had minimal relief with ibuprofen. On the second day, he developed nausea. He denied any history of headaches, blurred or double vision, numbness, weakness, tingling, loss of balance, vertigo, chest pain, palpitations, or shortness of breath. In the emergency room, he was afebrile with a heart rate of 78 beats per minute and regul...

Shortage of neurologists in the Brazilian Amazon
Neurologic disorders, including headache, epilepsy, and cerebrovascular disease, are common sources of medical consults and hospital admissions.1 Conditions such as stroke, the world's second leading cause of death, are medical emergencies that demand fast and efficient actions to reduce mortality and disability rates. These 2 points highlight the growing importance of neurology health care in developing countries.

Migraine and cryptogenic stroke: The clot thickens
The connection of migraine and stroke was first recognized 40 years ago in a study of stroke in young women.1 The study centered on the relationship of stroke and oral contraceptives, but uncovered an association of migraine with both ischemic and hemorrhagic stroke even in those not using the pill. Over the ensuing years, a growing number of epidemiologic,2 imaging,3 and genetic investigations4 have supported this early observation of an independent migraine/stroke link. Overall, the epidemiologic data have been strongest for ischemic stroke in young women with migraine with aura, but the relationship is also evident for ...

Age-specific association of migraine with cryptogenic TIA and stroke: Population-based study
Conclusions: In this population-based study of stroke etiology stratified by age, migraine was most strongly associated with cryptogenic TIA and ischemic stroke, particularly at older ages, suggesting a causal role or a shared etiology.

Pediatric cavernous sinus thrombosis: A case series and review of the literature
Conclusion: Our case series demonstrates low morbidity and mortality with early, aggressive surgical, antimicrobial, and anticoagulation therapies. Although anticoagulation and surgery were not associated with significantly different outcomes, more study is needed.

Mystery Case: A case of oil in ventricles: Deception for intraventricular hemorrhage
A 73-year-old woman with history of diabetic retinal detachment surgery 25 years ago in China presented with dizziness, headaches, and syncope. Noncontrast CT head (NCCT) showed hyperdensity within the left lateral temporal horn and fourth ventricle. Next day NCCT and MRI showed a shift of hyperdensity to the right frontal horn (figures 1 and 2).
