A Rare Case of Central Nervous System Tuberculosis Presenting as Transient Splenial Lesion: Case Report and Literature Review (P1.320)
Conclusions:Based on literature review, the transient splenial lesion of corpus callosum has never been reported in patients with CNS tuberculosis. The mechanisms underlying transient splenial lesions may due to intramyelinic edema and inflammatory cell infiltration. This hypothesis supported by the MR spectroscopy findings in our patient. Since early diagnosis and treatment can reduce mortality and morbidity, patients with isolated splenial lesion warrant diagnostic tests for CNS tuberculosis.Study Supported by:The authors report no disclosures relevant to the manuscript.Disclosure: Dr. Wu has nothing to disclose. Dr. Che...

Cardiac imaging in patients with arterial hypertension.
Authors: Antonini-Canterin F, Leiballi E, Martinis F, Pavan D Abstract Hypertension is considered the major modifiable risk factor for premature cardiovascular disease, being more common than other important risk factors as cigarette smoking, dyslipidemia, or diabetes [1]. In older patients, systolic pressure and pulse pressure are more powerful determinants of cardiovascular events than diastolic pressure [2]. Importantly, the cardiovascular risk associated with hypertension is significantly affected by the presence or absence of other major risk factors [3]. Among imaging features, left ventricular hypertrophy (L...

Posterior reversible encephalopathy syndrome in a postpartum hemorrhagic woman without hypertension: A case report
Rationale: Posterior reversible encephalopathy syndrome (PRES), which diagnosis is based on clinical symptoms and radiological features, is a neurotoxic disease characterized by a set of clinical manifestations, such as seizure, headache, visual, and/or consciousness disturbance. It is the first case of PRES followed by postpartum hemorrhage (PPH) without underlying disease. Patient concerns: A 37-year-old healthy woman had PPH after caesarean section. Six days after delivery, headache occurred suddenly, followed by episodes of clonus seizure. Diagnoses: Brain computed tomography showed ischemic stroke. However, magnetic...

Cerebral Developmental Venous Anomaly —Does it Prevent Stroke in Acute Sinus Thrombosis?
This 14-year-old boy developed progressively severe headache for three  weeks followed by acute encephalopathy and signs of increased intracranial pressure with systemic hypertension and bradycardia. Computed tomography head showed a large right transverse/sigmoid sinus thrombus and obstructive hydrocephalus (Figure). He underwent an urgent external ventricular drain placement. Magnetic resonance imaging demonstrated a large right transverse/sigmoid sinus thrombus, large bilateral cerebellar developmental venous anomalies (DVAs), and obstructive hydrocephalus.

Critical Illness-Associated Cerebral Microbleeds Brief Report
Conclusions—We have described a distinct microbleed phenomenon in the cerebral white matter of patients with critical illness. The specific cause of the microbleeds is unclear, but the pathogenesis may involve hypoxemia as the microbleeds are similar to those described with high-altitude exposure.

Diffuse carotid arteriosclerosis and stroke in a Patient with Schimke immune- osseous dysplasia
A 4-year-old girl, with history of Schimke immune-osseous dysplasia (SIOD) due to loss of function mutation of SMARCAL1 gene, was presented with acute onset left arm and leg weakness. Her brain magnetic resonance imaging (MRI) showed acute ischemic infarction of right hemisphere and narrowing of bilateral internal carotid arteries (Figure 1 A-C). Her medical history was significant for many features of SIOD: growth retardation, T-cell immunodeficiency, progressive renal dysfunction, and recurrent nephrotic syndrome in association with hypertension and hyperlipidemia.

Diffuse Carotid Arteriosclerosis and Stroke in a Patient With Schimke Immuno-osseous Dysplasia
This four-year-old girl with Schimke immuno-osseous dysplasia (SIOD), caused by a loss of function mutation of the SMARCAL1 gene, presented with acute left hemiparesis. Her brain magnetic resonance imaging (MRI) revealed an acute ischemic infarction in the right hemisphere and narrowing of both internal carotid arteries (Fig 1A-C). She exhibited many features of SIOD: growth retardation, spondyloepiphyseal dysplasia (Fig 2), T-cell deficiency, progressive renal dysfunction, and recurrent nephrotic syndrome in association with hypertension and hyperlipidemia.

Moyamoya disease associated with kidney angiodysplasia in a child.
CONCLUSION: Moyamoya disease is a rare cause of stroke in children. Its association with renal angiodysplasia is unusual and may be responsible for malignant hypertension. Cognitive impairment and social dependence have recently been recognized as an important unresolved social issue. Affected children require medical-surgical, social, and psychological care.

Acute Cerebral Venous Thrombosis Clinical Sciences
Background and Purpose—Cerebral venous thrombosis (CVT) affects venous hemodynamics and can provoke severe stroke and chronic intracranial hypertension. We sought to comprehensively analyze 3-dimensional blood flow and hemodynamic alterations during acute CVT including collateral recruitment and at follow-up.Methods—Twenty-two consecutive patients with acute CVT were prospectively included and underwent routine brain magnetic resonance imaging (MRI) and 4-dimensional flow MRI at 3 T for the in vivo assessment of cerebral blood flow. Neurological and MRI follow-up at 6 months was performed in 18 patients.Results—Three...

What Causes Hyperammonemia?
Discussion Reye’s syndrome (RS)is named for Dr. Douglas Reye who along with Drs. G. Morgan and J. Baral described encephalopathy and fatty accumulation and degeneration in children in a 1963 Lancet article. RS usually affects children but can occur at all ages. All organs can be affected but the liver and brain are primarily affected causing liver failure and encephalopathy as toxic metabolites (especially ammonia) accumulate, and intracranial hypertension and cerebral edema occurs. As the ammonia levels begin to rise (> 100 mg/dL) patients lose their appetite, have nausea and emesis and mental status changes whic...

MRI-visible perivascular space location is associated with Alzheimer's disease independently of amyloid burden
<span class="paragraphSection"><div class="boxTitle">Abstract</div>Perivascular spaces that are visible on magnetic resonance imaging (MRI) are a neuroimaging marker of cerebral small vessel disease. Their location may relate to the type of underlying small vessel pathology: those in the white matter centrum semi-ovale have been associated with cerebral amyloid angiopathy, while those in the basal ganglia have been associated with deep perforating artery arteriolosclerosis. As cerebral amyloid angiopathy is an almost invariable pathological finding in Alzheimer’s disease, we hypothesized that MRI-visibl...

Beta-Blocker Use Is Associated With Impaired Left Atrial Function in Hypertension Hypertension
BackgroundImpaired left atrial (LA) mechanical function is present in hypertension and likely contributes to various complications, including atrial arrhythmias, stroke, and heart failure. Various antihypertensive drug classes exert differential effects on central hemodynamics and left ventricular function. However, little is known about their effects on LA function.Methods and ResultsWe studied 212 subjects with hypertension and without heart failure or atrial fibrillation. LA strain was measured from cine steady‐state free‐precession cardiac MRI images using feature‐tracking algorithms. In multivariable models adju...
