The purpose of this study was to describe the pattern of diffuse enhancement seen on contrast-enhanced MR images in patients with subacute infarction. A retrospective study of 104 patients with the diagnosis of stroke who had undergone contrast-enhanced MR scanning within2 weeks of the inciting neurological event revealed 66 patients who demonstrated different patterns of contrast-enhanceme...

OBJECTIVE The pathophysiology of migraine with aura is thought to be related to cortical spreading depression and cortical hypersensitivity, in which inhibitory interneurons may play a role. Persistent migraine aura (PMA) without infarction is defined as auras that last longer than 1 week in the absence of infarction. We describe a case of persistent aura with a small occipital cortical infarct...

OBJECTIVES We hypothesized that occipital lobe infarctions differ from infarctions in other locations as to etiology, risk factors and prognosis among young adults. METHODS Location, etiology, risk factors and long-term outcome were evaluated among all young adults 15-49 years suffering from cerebral infarction in Hordaland County, Norway between 1988 and 1997. RESULTS The following variabl...
