Simultaneous Onset of Anterior and Middle Cerebral Artery Dissections with an Old Vertebral Artery Dissection
We report a patient with infarctions caused by simultaneous arterial dissections in the right anterior cerebral artery and the left middle cerebral artery and discuss the characteristic feature of this vascular disorder. A 53-year-old woman presented with a severe headache and a mild aphasia. Magnetic resonance imaging revealed multiple acute cerebral infarctions in the left temporal and right frontal lobes. The initial angiographic findings revealed arterial dissections of the anterior cerebral, left middle cerebral, and right vertebral arteries. The follow-up angiographic examination found improvement of the stenosis in ...

Clinical and Radiological Management and Outcome of Pregnancies Complicated by Cerebral Venous Thrombosis: A Review of 19 Cases
Conclusions: If magnetic resonance imaging is available, it should be used for the detection of CVT in all pregnant patients instead of computed tomography. Patients with parenchymal lesions, thrombophilia, and antiphospholipid syndrome had a greater risk of being left with neurologic sequelae. For pregnant patients with CVT, low molecular weight heparin in full anticoagulant doses should be continued throughout the pregnancy. Anticoagulant therapy did not appear to predispose patients to further intracranial hemorrhage.

123I-IMP-SPECT in a Patient with Cerebral Proliferative Angiopathy: A Case Report
We describe cerebral perfusion abnormalities in a patient with CPA by using N-isopropyl-p-[123I] iodoamphetamine single-photon emission computed tomography (123I-IMP-SPECT) and perfusion-weighted magnetic resonance imaging. The patient, a 13-year-old boy, had reversible focal neurological deficits unrelated to cerebral hemorrhage. 123I-IMP-SPECT at resting state showed preserved uptake within the vascular lesion, yet lower uptake in the area adjacent to the lesion. In addition, acetazolamide-stressed 123I-IMP-SPECT exhibited severely impaired cerebrovascular reactivity over the affected hemisphere, suggesting that his foca...

Eight and a Half Syndrome with Hemiparesis and Hemihypesthesia: The Nine Syndrome?
We report a 71-year-old man who presented with eight and a half syndrome associated with contralateral hemiparesis and hemihypesthesia, in which brain magnetic resonance imaging scans revealed a lacunar pontine infarction also involving the corticospinal tract and medial lemniscus. These features could widen the spectrum of pontine infarctions, configuring a possible “nine” syndrome.

A Case of Nonconvulsive Status Epilepticus with a Reversible Contralateral Cerebellar Lesion: Temporal Changes in Magnetic Resonance Imaging and Single-Photon Emission Computed Tomography Finding
A 67-year-old woman was brought to our institution because of unconsciousness. Clinical and electrophysiological findings lead us to diagnose her with nonconvulsive status epilepticus. Initial magnetic resonance imaging revealed hyperintensity in the left cerebral cortex and the right cerebellum on diffusion-weighted image and fluid-attenuated inversion recovery (FLAIR). Single-photon emission computed tomography showed increased blood flow in the left frontal cerebrum but not in the right cerebellum. The hyperintensity in the left cerebrum on the follow-up FLAIR was still present. The contralateral cerebellum remained und...

Cerebral Infarction in an HIV-Infected Patient with Combined Protein S and C Deficiency and a Patent Foramen Ovale
A 41-year-old male with a history of human immunodeficiency virus (HIV) infection developed motor aphasia, dysarthria, and right hemiparesis. A magnetic resonance imaging scan of the brain revealed a cerebral infarction in the territory of the left middle cerebral artery. The laboratory data showed decreased levels of protein S and protein C. Transesophageal contrast-enhanced echocardiography revealed a patent foramen ovale (PFO). Prothrombotic states, such as protein S and C deficiency, have been reported in HIV-infected patients. In addition, previous studies have reported prothrombotic states to be risk factors for PFO-...

Isolated Shoulder Palsy due to Cortical Infarction: A Case Report and Literature Review of Clinicoradiological Correlations
We report an 80-year-old woman with isolated shoulder palsy because of cortical ischemic infarction in the base of the left precentral gyrus as confirmed by brain magnetic resonance imaging. In our patient, cardiogenic embolism or Trousseau syndrome associated with lung cancer was considered the cause of ischemic infarction. Physicians should consider small cortical infarction, when a patient complains of sudden onset of shoulder weakness without pain. In line with the previous reports, a responsible cortical lesion in our patient corresponded to motor shoulder area in the motor homunculus reported to be located more media...

Cerebral Infarction in Both Carotid and Vertebrobasilar Territories Associated with a Persistent Primitive Hypoglossal Artery with Severe Dilated Cardiomyopathy
A persistent primitive hypoglossal artery (PPHA) is a relatively rare vascular anomaly of a persistent carotid–basilar anastomosis. A 76-year-old man with severe dilated cardiomyopathy suddenly lost consciousness. A magnetic resonance imaging scan of his brain revealed extensive infarction in the carotid and vertebrobasilar territories. Magnetic resonance angiography revealed a PPHA and occlusion of the left internal carotid artery and vertebrobasilar artery. Cardioembolic infarction associated with a PPHA should be recognized as a possible cause of multiple infarctions in both the carotid and vertebrobasilar distributio...

A Case of Superficial Hemisensory Dysfunction due to Operculo-insular Infarction: Radiological Depiction of Thalamocortical Projections to the Secondary Somatosensory Cortex
A 64-year-old obese man developed hypesthesia in the left arm and leg. Neurological examination revealed decreased senses of pain, touch, and temperature in the left face, arm, trunk, and leg. Remaining functions were normal. Electrocardiogram showed atrial fibrillation. Somatosensory-evoked potentials using the stimulation in the median nerve were normal on both sides. Brain magnetic resonance imaging revealed acute infarction in the right parietal operculum and insula. There were no pathognomonic lesions in the postcentral gyrus, the thalamus, or the brain stem. Cardioembolic operculo-insular infarction was diagnosed. Di...

Ipsilateral Sensorimotor Deficits in Lateral Medullary Infarction: A Case Report
The patient, a 32-year-old man, presented with sudden onset of occipital headache, vertigo, dysarthria, gait ataxia, right Horner syndrome, numbness of the right hand, and mild right hemiparesis. On magnetic resonance imaging, an acute small infarction was located on the right side of the caudal medulla extending dorsomedially. Magnetic resonance angiography showed severe right vertebral artery stenosis. Lateral medullary infarction associated with ipsilateral sensorimotor deficits in the limb is very rare, and the lesion probably involved the ipsilateral dorsal column or decussating lemniscal fibers and corticospinal fibe...

Associations of Durations of Antiplatelet Use and Vascular Risk Factors with the Presence of Cerebral Microbleeds
In conclusion, we found a significant association between aspirin use and deep or infratentorial microbleeds, but this association may reflect the presence of hypertension as a confounding factor.

Retrosplenial Amnesia without Topographic Disorientation Caused by a Lesion in the Nondominant Hemisphere
We report the case of a 68-year-old right-handed man who was admitted to our hospital because of sudden onset of headache. On admission, he presented with left homonymous hemianopsia, disorientation, and recent memory disturbance; however, he had normal remote memory and digit span. He was able to recall the room layout of his house and describe the route from the nearest station to his home on a map. However, at the hospital, he sometimes lost his way because of amnesia. Computed tomography (CT) and magnetic resonance imaging revealed a subcortical hematoma in the right occipital forceps and the parietal lobe, involving t...
