Abstract
A 56-year-old right-handed man was referred to our hospital for evaluation of sudden-onset transient quadrantanopia, which was followed by throbbing headache consistent with migraine with aura (MA). Magnetic resonance imaging (MRI) of the right parieto-occipital cortex on admission showed a hyperintense region on diffusion-weighted imaging, which disappeared 7 days later. A small cortical infarct in the parieto-occipital cortex can cause MA-like headache, and the present infarct lesion was only detectable on MRI during the acute phase. Performing MRI for patients with suspected acute MA might help identify the cause of MA-like headache and ensure appropriate management of patients.
期刊介绍：
The international effort to understand, treat and control disease involve clinicians and researchers from many medical and biological science disciplines. The Journal of Nippon Medical School (JNMS) is the official journal of the Medical Association of Nippon Medical School and is dedicated to furthering international exchange of medical science experience and opinion. It provides an international forum for researchers in the fields of bascic and clinical medicine to introduce, discuss and exchange thier novel achievements in biomedical science and a platform for the worldwide dissemination and steering of biomedical knowledge for the benefit of human health and welfare. Properly reasoned discussions disciplined by appropriate references to existing bodies of knowledge or aimed at motivating the creation of such knowledge is the aim of the journal.
