  ABSTRACT: We report the case of a 56-year-old man with acute onset of de-novo stabbing, pulsating and diffuse headache with subsequent appearance (within few minutes) of posterior fossa symptoms (vomiting, postural instability, anisocoria, incoordination, dysarthria, retropulsion) lasting 9-12 h. Recurrent hypertensive crises were detected during the acute observation in the Emergency Room, even in the absence of previous history of hypertension. Once subarachnoid hemorrhage and focal lesions (vascular and non-vascular) were excluded, brain computerized tomography-angiography and digital subtraction angiography disclosed the presence of left persistent primitive hypoglossal artery with bilateral vertebral artery hypoplasia and a slight aneurysmal dilation of the anterior communicating artery. Brain magnetic resonance study performed 24 h after onset of symptoms was negative for recent ischemic lesions. The clinical features of this rare vascular condition are discussed as a possible cause of magnetic resonance (diffusion weighted imaging) negative vertebro-basilar transient ischemic attack.

• Article: Persistent trigeminal artery causing "double" neurovascular conflict.

  ABSTRACT: We report the case of a 73-year-old woman who presented with right VI nerve palsy and homolateral atypical trigeminal neuralgia; standard neuroradiological investigation of orbital/retroorbital regions and intracranial arteries excluded the most commonly demonstrable underlying causes while brain magnetic resonance (T1-weighted fat suppression; T2-weighted thin-section) and magnetic resonance angiography disclosed the evidence of "double" neurovascular conflict because of persistent trigeminal artery with aneurysmal dilation. A role of this almost rare vascular condition in causing painful ophthalmoplegia is discussed.

• Article: Complications of migraine: migrainous infarction.

  ABSTRACT: Migraine and cerebrovascular disorders are comorbid diseases and the overlap of their clinical symptoms has relevant diagnostic and therapeutic implications. The prototypic condition of this relationship is reproduced by a clinical event named migrainous infarction (MI), listed by the ICHD-II among the "complication of migraine." We discuss the diagnostic criteria proposed for this rare condition with regard to the epidemiological studies and the clinicopathogenetic implications. In the clinical setting therefore, "possible" cases of migrainous infarction should undergo an extended diagnostic workup to rule out symptomatic migraine due to extra/intra-cranial vascular pathology (artery dissection/malformations, venous thrombosis) and to exclude a causal role for other conditions. These include patent foramen ovale and thrombophylic status that may become critical risk factors for stroke, particularly among migraineurs, in coincidence with precipitating factors that should be more accurately considered in each single case.
