“…22,32,36,49 ICVT has been described as having a good prognosis if diagnosed early and anticoagulant therapy is initi-ated. 3,5,29,39 Our experience supports this, with 5 patients in this case series experiencing resolution of symptoms after receiving anticoagulant therapy. In 2 patients, anticoagulation therapy was not administered due to concern over the potential exacerbation of severe SDHs.…”

The majority of these patients were adult females, consistent with published data. Seizures and headaches were the most common presenting symptoms. Hypercoagulable state and intracranial hypotension, both known risk factors for thrombosis, were the most commonly noted ICVT risk factors. Intraparenchymal involvement was prevalent in nearly all ICVT cases and presented as vasogenic edema, early intraparenchymal hemorrhage, or hemorrhagic venous infarction. Susceptibility-weighted imaging was the most sensitive imaging technique in diagnosing ICVT.

Isolated cortical vein thrombosis (ICVT) is extremely rare. Only single case or small series of ICVT have been reported; clinical details are still uncertain. We report a case of isolated superficial sylvian vein thrombosis with exceedingly long cord sign. A 14-year-old female with severe sudden onset headache visited our hospital. Fluid attenuated inversion recovery and echo-planar T 2 * susceptibility-weighted imaging (T 2 *SW) showed a long cord sign on the surface of the sylvian fissure. The patency of dural sinuses and deep cerebral veins were confirmed by magnetic resonance venography (MRV), and diagnosis of ICVT was made. She recovered completely without anticoagulant agents. To clarify the clinical characteristics of ICVT, we reviewed 51 ICVT cases in the literature. In many cases, T 2 *SW was the most useful examination to diagnose ICVT. In contrast with general cerebral venous thrombosis, MRV and conventional angiography were either supporting or useless. Anastomotic cortical veins were involved frequently; symptoms of gyri around the veins were common. It also suggested that ICVTs of the silent area might have been overlooked because of nonspecific symptoms, and more patients with ICVT may exist. In cases involving patients with nonspecific symptoms, the possibility of ICVT should be considered.

“…In our population, CVT was as frequent as RCVS and CAA. Cerebral vein thrombosis is an increasingly recognized cause of cSAH and some authors suggest that this might be related to technological advances made in noninvasive diagnostic radiology during the last decades 8,9 . Another possible explanation may be that our cohort was younger than other series and had a female predominance; CVT is more frequent in such populations 10 .…”

Nontraumatic convexity subarachnoid hemorrhage is an increasingly recognized subtype of subarachnoid bleeding. Objective: Our aim was to describe the etiology and clinical features of a cohort of patients with convexity subarachnoid hemorrhage. Methods: We retrospectively analyzed all cases of convexity subarachnoid hemorrhage admitted to our hospital between January 2012 and April 2017. Demographic features, clinical characteristics, complementary investigations, etiology and mortality were assessed. Twenty patients (65% females) were identified. Mean age: 53 years (range, 15-86 years). Results: Symptoms on admission: headache (65%), sensory and/or motor symptoms (50%) and seizures (35%). Commonest causes: cerebral vein thrombosis (20%), reversible cerebral vasoconstriction syndrome (20%) and cerebral amyloid angiopathy (20%). Two patients died. Conclusion: Convexity subarachnoid hemorrhage may be related to a wide spectrum of etiologies. In our patients, an increased prevalence of cerebral vein thrombosis was observed. Mortality was low and not related to the bleeding itself.Keywords: cerebral amyloid angiopathy, etiology; sinus thrombosis, intracranial; subarachnoid hemorrhage. RESUMOA hemorragia subaracnóidea não traumática da convexidade é um subtipo cada vez mais reconhecido de sangramento subaracnóideo. Objetivo: Nosso objetivo foi descrever a etiologia e as características clínicas de uma coorte de pacientes com hemorragia subaracnóidea da convexidade. Métodos: Foram analisados retrospectivamente todos os casos de hemorragia subaracnóidea da convexidade admitidos em nosso hospital entre janeiro de 2012 e abril de 2017. Foram avaliados os aspectos demográficos, características clínicas, investigações complementares, etiologia e mortalidade. Vinte pacientes (65% mulheres) foram identificados. Média de idade: 53 anos (intervalo, 15-86). Resultados: Sintomas na admissão: dor de cabeça (65%), sintomas sensitivos e/ou motores (50%) e convulsões (35%). Causas mais comuns: trombose venosa cerebral (20%), síndrome de vasoconstrição cerebral reversível (20%) e angiopatia amilóide cerebral (20%). Dois pacientes morreram. Conclusão: A hemorragia subaracnóidea da convexidade pode estar relacionada a um amplo espectro de etiologias. Em nossos pacientes, observou-se uma maior prevalência de trombose venosa cerebral. A mortalidade foi baixa e não relacionada à própria hemorragia.Palavras-chave: angiopatia amiloide cerebral, etiologia; trombose dos seios intracranianos; hemorragia subaracnóidea.Nontraumatic nonaneurysmal convexity subarachnoid hemorrhage (cSAH) is an increasingly recognized subtype of subarachnoid bleeding localized in one or more cortical sulci of the brain without involvement of the neighboring parenchyma or extension to the interhemispheric fissure, basal cisterns or ventricles 1 . These features help to distinguish cSAH from aneurysmal bleeding and nontraumatic perimesencephalic subarachnoid hemorrhage. Recently, many case series have described the clinical features, etiology and outcome of t...
