Introduction Acquired haemophilia is an exceptional haematological disease, with a prevalence of about 1 case per million population per year, affecting predominantly the elderly (people between 60 and 80 years old), and due to the development of auto-antibodies against factor VIII:C (FVIII) [1]. Frequent revealing symptoms are muscle or skin haematomas, subglottic haemorrhages, retroperitoneal bleeding or bleedings in the gastro-intestinal and genitourinary tracts. These haemorrhagic complications can lead to death in 15–20% of cases, despite heavy immunomodulating therapy [1, 2]. Neurological complications are exceptional in this disease, especially spontaneous subdural haematomas (SDH) [1, 2].

Intravascular lymphomatosis (IVL) is a rare form of high-grade malignant non-Hodgkin’s lymphoma, characterized by the proliferation of neoplastic lymphoid cells within the lumen of small-caliber blood vessels, producing localized vascular occlusion. CNS involvement is found in 75 to 85% of cases.1,2⇓ The clinical presentation is variable and can mimic other neurologic conditions.3 We report a patient with IVL presenting with an isolated, rapidly progressive spinal cord syndrome. A 71-year-old retired woman was admitted because of rapidly progressive paraparesis, accompanied by dysuria and urinary incontinence. At admission, neurologic examination revealed paraparesis with a pyramidal syndrome, T12 hypoesthesia, and anal hypotonia. The rest of the examination was normal. Laboratory studies showed an elevated erythrocyte sedimentation rate and C-reactive protein. Spinal MRI revealed an increase in the size of the conus medullaris and a high signal in T2-weighted sequences. There was no gadolinium enhancement in T1-weighted sequences. Spinal ischemia was diagnosed. Cardiac and aortic ultrasonography were normal and a spinal arteriography …

Resume Introduction La prise en charge des patients ayant un accident vasculaire cerebral (AVC) dans les unites neuro-vasculaires (UNV) diminue la proportion de deces et de handicap, independamment de l’acces aux traitements d’urgence comme la thrombolyse intraveineuse. Au CHU de Tours, une filiere d’accueil direct des patients atteints d’AVC permettant l’utilisation du traitement par thrombolyse intraveineuse a ete mise en place en juin 2003. Methodes Nous avons conduit une etude prospective pendant 18 mois, pour evaluer le fonctionnement de la filiere neuro-vasculaire, en recueillant les donnees de prise en charge et de devenir de tous les patients qui y etaient admis. Dans un second temps, ces donnees ont ete comparees a celles recueillies pendant 6 mois aux urgences en 2002, pour les patients suspects d’AVC. Nous avons egalement etudie les conditions d’utilisation du traitement par thrombolyse intraveineuse. Resultats Trois cent soixante-quatre patients ont ete inclus dans l’etude. La creation de la filiere s’est accompagnee d’une diminution significative des delais d’admission des patients et des delais d’imagerie, et d’une plus grande implication des services de transport d’urgence (SAMU). La proportion de patients ayant une mauvaise evolution est moindre dans la filiere, cette diminution ne restant significative apres ajustement que pour les patients ayant un AVC hemorragique. Les conditions d’utilisation du traitement thrombolytique dans notre centre sont comparables a celles de la litterature en terme de securite et d’efficacite. Conclusion Cette etude montre que la creation d’une filiere neuro-vasculaire d’accueil direct et de thrombolyse s’est globalement accompagnee d’une amelioration de la qualite des soins, avant meme la creation d’une unite neuro-vasculaire repondant aux recommandations.

The clinical presentation of stroke usually includes sensory–motor impairment, cranial nerve palsies, or cognitive dysfunction. Disorders in behaviour are less frequently seen. The case of a patient with a very disturbing presentation, which included a disturbance in vigilance, bilateral third nerve palsy and masturbating behaviour, is presented. The topography of the lesions and its implications on the deficits observed are discussed.

We report on a man with type I hereditary angioedema (HAE) who presented with repeated transient neurologic deficits, totally regressive after a specific C1-inhibitor (C1 INH) injection. Hereditary angioedema, first described in 1888,1 is an autosomal dominant disease, affecting up to 1/50,000 persons, defined in type I as a C1 INH deficiency.2 It is clinically characterized by recurrent edematous crisis at various body sites: mainly relapsing skin swellings, abdominal pain attacks, and life-threatening upper airway obstructions. Neurologic manifestations are exceptionally reported in this affection.3 ### Case report. A 61-year-old man was admitted for the sudden onset of a right sensory-motor deficit. Since childhood, he had had serpiginous erythema and recurrent abdominal pain attacks. The diagnosis of HAE type I was established when he was 14 years old. The disease was still active in 2008 (2 abdominal or respiratory attacks during 3 or 4 days/month), despite a high dose of prophylactic treatment with danazol (600 mg/day). He was an active smoker (40 packs/year) and had a dyslipidemia probably due to danazol. He had no arterial hypertension. At admission, the deficit was …

Glasgow Coma Scale score was E3 V1 M6, the blood pressure 130/70 mm Hg, the pulse 80/min, and she was apyretic. The NIH Stroke Scale score was 25. Throat examination revealed a mild inflammation with swelling of the peritonsillar area. Blood examinations were normal. Brain MRI with diffusion-weighted images demonstrated a large cerebral infarction in the left middle cerebral artery territory, MR angiography showed an irregular stenosis of the left ICA extending from the bulb to the base of the skull. The MR axial scans looking for mural hematoma were noninterpretable due to the clouding of consciousness and agitation, but CT angiography showed widening of the external diameter of the ICA with a crescentic hypodensity around the enhanced narrowed artery ( fig. 1 ) consistent with a mural hematoma. Ultrastructural examination of the skin did not show abnormalities of the elastic tissue, and Ehlers-Danlos syndrome, Marfan syndrome, polycystic renal syndrome, 1-antitrypsin deficiency and fibromuscular dysplasia were excluded. The MR angiography performed 3 months after the onset of symptoms showed recanalization of the left ICA with a slight persistent narrowing of the artery ( fig. 2).

Decompressive hemicraniectomy (DC) is the only treatment which has proved to be effective in malignant middle cerebral artery infarction (MMI), showing its efficiency in reducing mortality and handicap in patients of less than 60 years old operated in the first 48 h (1). Recently, new data concerning the evolution and the patients’ quality of life have demonstrated that the reduction in mortality is not associated with a very severe handicap and that the neurological sequelae are compatible with a good quality of life, contrary to what has been put forward by certain physicians who are reluctant in performing DC (2,3). However, it seems that DC still remains underemployed in certain centers and countries in Europe (4). A French multicentric prospective study performed recently acknowledged a large heterogeneity in the resort to DC according to the surgical teams (2). The authors evaluated prospectively the outcome and the quality of life of 63 patients operated on, in five university hospital centers between 2004 and 2011. The mortality rate was 27%. Among the survivors, at two-years, 68% of the patients had a Rankin scale of ≤3, 28% a Rankin scale of 2, and 32% had a Rankin scale of 4. None of the patients were bedridden. After two-years, 64% of the patients were satisfied with their quality of life and 86% gave their consent retrospectively to the surgical procedure. Moreover, 93% of the patients were able to return home and 76% of the caregivers considered that their workload was from light to moderate, no matter what was the patient’s disability. The underuse of decompressive craniectomy in MMI does not seem to have scientific rationale, and is more based on subjective value judgment. The physicians should be reassured by the available information about DC in MMI, especially on the quality of life and the patient’s satisfaction and that of the families. It would not appear at present to justify on ethical grounds denying some patients the opportunity of this life-saving procedure.

Introduction L’hemosiderose superficielle (HS) est due a un saignement sous arachnoidien repete dont la cause reste inconnue dans la moitie des cas. Classiquement, elle se presente par une ataxie, une hypoacousie et des signes pyramidaux. Observation Un patient, âge de 84 ans, droitier, ancien medecin, fut hospitalise pour une deterioration cognitive evoluant depuis plusieurs semaines, associee a des troubles de la marche, un syndrome dysexecutif essentiellement visuo-constructif, et des hallucinations visuelles elaborees. Les explorations biologiques, et le scanner cerebral, etaient normaux. Il existait une augmentation isolee des hematies (250/mm 3 ) dans le LCR. L’EEG montrait une souffrance hemispherique droite. L’IRM retrouva une hemorragie sous arachnoidienne subaigue hemispherique droite, et des depots spontanement hyperintenses en T1 caracteristiques d’une hemosiderose superficielle droite diffuse. Aucune lesion sous jacente ne fut detectee et le deces survint quelques semaines plus tard. Discussion Les symptomes de l’HS resultent de depots d’hemosiderine dans la region cerebelleuse et medullaire haute. Le scanner cerebral, et le LCR peuvent etre normaux. L’aspect typique de l’IRM en T1 et echo de gradient pose le diagnostic. On peut proposer un traitement par chelateur en fer mais seule l’ablation de la cause est efficace. Les explorations etiologiques doivent etre completes chez le sujet jeune. Conclusion L’HS peut etre hemispherique, unilaterale, et entrainer une encephalopathie severe avec troubles psychiatriques. En l’absence d’etiologie retrouvee, la lesion hemorragique peut rester evolutive et l’issue fatale.

BACKGROUND Echocardiography is routinely used to identify potential cardiac sources of embolism (CSE) in the acute phase of ischemic stroke (IS). We know that transoesophageal echography (TEE) is superior to detect CSE than transthoracic echography (TTE). However, the indications of each technique remain controversial. We aimed to evaluate the diagnostic yield (DY) and the therapeutic impact (TI) of echocardiography (both techniques combined) in IS and to analyze impact of clinical factors on these values. METHODS We included consecutive IS patients over a period of 22 months. All patients underwent TTE, and selected patients (young or with a high suspicion of cardioembolic origin) then underwent TEE. DY (detection of CSE) and TI (introduction of oral anticoagulant, closure of patent foramen ovale and targeted cardiologic consultation) were systematically evaluated. RESULTS We analyzed 300 patients (mean age 61 years). All patients underwent TTE and 127 patients underwent TTE and TEE. Echocardiography overall detected CSE in 22% of patients with a TI in 11% of all cases. The TI was higher in patients less than or equal to 55 years of age. In contrast to other studies, the DY and TI of echocardiography were not associated with vascular risk factors. CONCLUSIONS Echocardiography, as currently practiced in our stroke unit, allows detection of CSE in one patient in five, and leads to change in therapy in half of these cases. Our results suggest that TTE should be used for all patients admitted for IS, and to limit the use of TEE to younger patients.

Introduction Ischemic stroke (IS) is a frequent pathology, burdened by high rate of recurrence and significant morbidity and mortality. There are several causes of IS, affecting prognosis, outcomes and management, but in many cases the etiology remains undetermined despite comprehensive research. We hypothezised that atrial fibrillation (AF) was largely involved in this pathology but was underdiagnosed by standard methods. The aim of this study was to determine the incidence of AF in cryptogenic IS, by using continuous monitoring of the heart rate over several months. The secondary objective was to test the predictive value of atrial vulnerability study towards spontaneous AF. Methods and results We prospectively enrolled 24 patients under 75 years: 15 men and 9 women of mean age 48.8± 13.6 years who experienced cryptogenic IS presumed of cardioembolic mechanism within the last 4 months. Any cause of IS was excluded by normal 12-lead ECG, 24-hour Holter monitoring, echocardiography, cervical Doppler, haematological and inflammatory tests. All patients underwent electrophysiological study. 7 patients (29.2%) had inducible arrhythmia during programmed atrial stimulation and 9 (37.5%) had a latent vulnerability index (LVI) Conclusion This study shows that contrary to what was expected, AF does not appear to be a common pathology in patients under 75 years with unexplained IS. The use of ILR should not be generalized in the systematic assessment of these patients because of its unprofitability. Finally this study attests the poor value of atrial vulnerability study for predicting spontaneous AF in such patients.
