Cerebral blood flow alterations in migraine patients with and without aura: An arterial spin labeling study
ConclusionIn this study, CBF abnormalities of MwA were identified in multiple brain regions, which might help better understand migraine-stroke connection mechanisms and may guide patient-specific decision-making.

Infratentorial developmental venous anomaly concurrent with a cavernoma and dural arteriovenous fistula
A 32-year-old woman underwent a head computed tomography scan after a traffic accident. A calcification in the left cerebellar hemisphere was disclosed. She did not complain of any symptoms, but neurological examination revealed cerebellar ataxia. She did not have any preceding episodes since birth, such as acute-onset headache. Magnetic resonance imaging showed past hemorrhage of the calcification lesion suggestive of a cerebellar cavernoma. A dilated vascular structure was also observed (Fig.  1A, B).

Clinical characteristics and perfusion-computed tomography alterations in a series of patients with migraine with aura attended as stroke code
CONCLUSION: This is, to the best of our knowledge, the largest series of patients with MA managed as presumed stroke with clinical characteristics and PCT. In our study, most patients were young and had a prior history of migraine. PCT was normal in 88% of cases, with patients being still symptomatic by the time they were scanned. Further research will clarify the presence and type of PCT alterations in this entity.PMID:34862603 | DOI:10.1111/head.14243

Epidemiology, investigation, management, and outcome  of headache in emergency departments (HEAD study)-A multinational observational study
CONCLUSION: Diagnosis and management of headache in the ED is challenging. A small group of patients have a serious secondary cause for their symptoms. There is wide variation in the use of neuroimaging and treatments. Further work is needed to understand the variation in practice and to better inform international guidelines regarding emergent neuroimaging and treatment.PMID:34726783 | DOI:10.1111/head.14230
