Scintillating scotoma

BACKGROUND: Complex migraine aura in teenagers can be complicated to diagnose. The aim of this study was to present detailed features of migraine aura in teenage migraineurs. METHODS: This cross-sectional study was conducted in the period from 2008 till 2013. A total number of 40 teenage migraineurs (20 females and 20 males) met criteria for this study. The patients were interviewed using a specially designed questionnaire for collecting data about migraine aura features...

BACKGROUND: Cervical carotid dissection is more common in extracranical vessel: internal carotid artery dissection (ICAD) is typical, vertebral artery dissection is uncommon, common carotid artery dissection (CCAD) is rare and even a more rare cause of ischemic stroke. Cervical artery dissections account up to 20-25% of ischemic strokes in young patients. Isolated and spontaneous common carotid artery dissection without aortic damage is unique. Indeed in the Literature 8 cases were identified...

A migraine is a recurring neurological disorder characterized by unilateral, intense, and pulsatile headaches. In one-third of migraine patients, the attacks are preceded by a visual aura, such as a slowly-propagating scintillating scotoma. Migraine aura is thought to be a result of the neurovascular phenomenon of cortical spreading depression (SD), a self-propagating wave of depolarization that spreads across the cerebral cortex. Several animal experiments have demonstrated that cortical SD causes intracranial neurogenic inflammation around the meningeal blood vessels, such as plasma protein extravasation and pro-inflammatory peptide release...

BACKGROUND: Since the mid-19th century, epistaxis and migraine have been occasionally associated with each other. Nevertheless, we found only two cases in the contemporary medical literature. Sporadic hemiplegic migraine is a subtype of migraine with reversible motor deficits, without similar episodes in relatives. CASE: We describe a 47-year-old male with a history of migraine with a scintillating scotoma starting at the age of 20. In some of the episodes, he developed epistaxis in the resolution phase of migraine...

This article reports the case of a 14-year-old boy who was presented in the case conference with symptoms of decreased visual acuity, scintillating scotomas and photophobia. Physical examination revealed right facial paralysis, parotid gland swelling, high fever and poor general condition. Ophthalmoscopy revealed anterior and posterior uveitis including macular edema and chorioretinal infiltrates. Angiography revealed a dense pattern of hyperfluorescent lesions and these observations resulted in the diagnosis of Heerfordt syndrome...

We report a very unusual case of a composite high-grade glioma and rhabdoid tumor in an adult. A 22-year-old woman presented with scintillating scotoma due to a solid tumor with surrounding brain edema in the right occipital lobe. The tumor was grossly resected. Histological examinations showed that the tumor was mainly composed of INI1-positive high-grade glioma tissue containing an INI1-negative rhabdoid component. She received radiation therapy and chemotherapy. Three months after the surgery, she again complained of visual disturbances, and tumor recurrence within the resection cavity was noted...

Until the second half of the eighteenth century, the very definition of migraine as hemicrania (pain felt in one side of the head) eclipsed symptoms that were then considered as "marginal", although tingling sensations, speech impairment and visual impairment had already been described by Piso and Wepfer. The possibility of a migraine without a headache nevertheless started to be envisaged, inviting one to re-evaluate the status of these phenomena. But, as paradoxical as it may seem, it is in the field of astronomy that some of these phenomena such as visual aberrations were analyzed systematically and acknowledged to be migrainous...

We compared the appearance of a line passing through the optic-disc blind spot with that of lines passing just medial or just lateral to the blind spot. Though there is no well-defined gap in the line, we see a consistent difference, which is hard to describe. On the other hand, during a migraine aura experienced by one of us, lines passing through scintillating scotomas showed clear sharply defined gaps.

BACKGROUND: Polyglycolic-polylactic acid (PGLA) coils induce inflammation within a cerebral aneurysm, which in turn is hypothesized to decrease aneurysm recurrence. We present 2 patients, who after aneurysm coiling with PGLA coils, developed mild symptoms and extensive magnetic resonance imaging (MRI) white matter changes. METHODS: The first patient was a 46-year-old woman who underwent coiling of a 6.8 × 6.8 × 7.0-mm incidentally discovered basilar apex aneurysm...

DEFINITION: Sclerotherapy is defined as the targeted elimination of small vessels, varicose veins and vascular anomalies by the injection of a sclerosant. The aim of sclerotherapy is to damage the vessel wall and transform it into a fibrous cord that cannot be recanalized. It is a simple, cost-effective, efficacious and esthetically acceptable modality for both therapeutic and esthetic purposes. INDICATIONS: Therapeutic indications include varicose veins and vascular malformations...

Visual aura is a common presenting symptom of migraine to both neurologists and ophthalmologists. Features such as photopsia, fortification spectra, and the slow propagation of a scintillating scotoma across the visual field are usually considered diagnostic features of the visual aura of migraine. In the vast majority of cases, the diagnosis can be made without the need for further investigations. We present 9 patients and a further 31 cases from the literature who experienced visual aura fulfilling the diagnostic criteria for migraines but caused by focal occipital pathology...

The intracarotid sodium amobarbital (Amytal) test, the Wada test, remains an efficient test for evaluation of language and memory function. However, due to a world shortage of amobarbital, it has become necessary to investigate the use of alternatives. We report the efficacy of the Wada test using secobarbital sodium (Ional) in determining language dominance. An accurate determination of language dominance was required in 43 patients preoperatively at our institution. Patients underwent the Wada test using secobarbital sodium, effectiveness and safety were assessed...

OBJECTIVE: To identify susceptibility loci for visual migraine aura in migraine families primarily affected with scintillating scotoma type of aura. METHODS: We included Finnish migraine families with at least 2 affected family members with scintillating scotoma as defined by the International Criteria for Headache Disorders-II. A total of 36 multigenerational families containing 351 individuals were included, 185 of whom have visual aura and 159 have scintillating scotoma...

INTRODUCTION: Migraine with aura is characterized by reversible focal neurological symptoms preceding or accompanying headache. Visual aura is the most common type of aura and its patognomic symptoms are scintillating fortification migrating across the visual field or scintillating scotoma. However, the symptoms are not always so typical and clinical doubts are greater when negative symptoms (loss of vision, numbness or paresis) are present. Differential diagnosis of migraine with aura includes in the first place transient ischemic attack (TIA) as well as epilepsy...

BACKGROUND: Transseptal catheterization (TSC) is performed during catheter ablation involving the lefthand side of the heart. TSC causes a transient iatrogenic atrial septal defect that can predispose patients to migraine episodes. However, isolated migraine aura episodes in patients undergoing TSC have not been described. METHODS: Five hundred seventy-one procedures involving TSC were performed over a 3-year duration. Of these, 3 patients presented with visual symptoms in the first month after the procedure...

Occasionally patients in the stroke age-bracket over 40 years have unexplained transient cerebral ischemic attacks in association with normal cerebral angiograms. From this group, 120 have been collected in whom the transient episodes resembled the neurological accompaniments of migraine. According to symptoms, the patients were categorized as follows: visual accompaniments (patients with only ordinary scintillating scotoma were excluded), 25; visual and paresthesias, 18; visual and speech disturbance, 7; visual, and brain stem symptoms, 14; visual, paresthesias, and speech disturbance, 7; visual, paresthesias, speech disturbance, and paresis, 25; recurrence of old stroke deficit, 9; miscellaneous, 8...

OBJECTIVES: To determine the pathogenesis and course of transient focal neurologic symptoms in pregnant women and to identify prognostic variables that will enable targeted workup. DESIGN: Case-control series. SETTING: Tertiary care university hospital. PATIENTS: Pregnant patients with acute transient focal neurologic symptoms. Women with histories of migraine, recurrent thromboembolism, or cerebrovascular disease were excluded...

A variety of etiologies underlie the neurophysiological imbalance resulting in chorea. We report a 57-year-old woman with a long-history of migraine who suddenly experienced concurrent scintillating scotoma and rapid involuntary movement of her neck and right extremities. Diffusion-weighted magnetic resonance imaging (MRI) failed to detect any fresh ischemic and/or hemorrhagic lesions. Xenon-computed tomography (CT) disclosed gross reduction in the cerebral blood flow (CBF) of the left occipital area. With precise mapping to the brain atlas, extreme hyperperfusion in the motor thalamus was found on the left side...

Migraine affects the cortical physiology and may induce dysfunction both ictally and interictally. Although visual symptoms predominate during aura, other contiguous cortical areas related to less impressive symptoms are also impaired in migraine. Answers from 72.2% migraine with aura and 48.6% of migraine without aura patients on human faces and objects recognition, colour perception, proper names recalling and memory in general showed dysfunctions suggestive of prosopagnosia, dyschromatopsia, ideational apraxia, alien hand syndrome, proper name anomia or aphasia, varying in duration and severity...

The most frequent type of migraine aura is the typical one in which the most frequently occurring aura type are visual phenomena. Types of visual aura may be different. Scintillating scotoma, fortification zigzags (teichopsiae), fragmentation of the visual image are typical illusions in visual aura. The visual illusion of a typical corona phenomenon was represented as a visual migraine aura symptom. The extra edges of the corona phenomenon are commonly seen around the perceptual images of objects. The corona phenomenon is strongly associated with visual loss and the presence of elementary geometric illusions...
