Density heterogeneity and fluid-blood levels in patients aged over 55 with lobar hematoma.
CONCLUSION: Density heterogeneity and, to a lesser degree, FBLs are frequently seen in patients aged>55 with LH. FBLs may also be associated with CAA-related hemorrhage. PMID: 27338204 [PubMed - as supplied by publisher]

Reversible cerebral vasoconstriction syndrome: A rare pediatric cause of thunderclap headaches.
We report on a case of a 13-year-old boy presenting with acute severe headaches, triggered by physical exertion. His past medical history was uneventful. Moderate headache persisted between exacerbations for 4 weeks. He secondarily presented with signs of intracranial hypertension. Brain magnetic resonance angiography (MRA) revealed multifocal narrowing of the cerebral arteries. A glucocorticoid treatment was started based on the hypothesis of primary angiitis of the CNS. The symptoms rapidly improved, and repeat angiography at 3 months showed no vasoconstriction. Although pediatric cases are rare, RCVS should be considere...

Aldosterone producing adenoma with a somatic KCNJ5 mutation revealing APC dependent Familial Adenomatous Polyposis.
CONCLUSIONS: This case report underlines the need of establishing the frequency of germline APC variants in patients with primary aldosteronism and bilateral macronodular adrenal hyperplasia, as their presence may predispose to APA development and severe hypertension well before the first FAP symptoms appear. From a mechanistic point of view, it supports a two-hit model for APA development, whereby the first hit drives increased cell proliferation while the second hit specifies the pattern of hormonal secretion.

Clinical Outcome Predicted by Collaterals Depends on Technical Success of Mechanical Thrombectomy in Middle Cerebral Artery Occlusion
This study aimed to analyze the effects of technical outcome of mechanical thrombectomy (MTE) on the associations between collateral status, assessed with pretreatment computed tomography angiography (CTA), and neurological and functional outcome, as well as associations between collaterals and metabolic risk factors (arterial hypertension, diabetes, hyperlipidemia, overweight).

Association of Subjective and Objective Sleep Duration as well as Sleep Quality with Non-Invasive Markers of Sub-Clinical Cardiovascular Disease (CVD): A Systematic Review.
CONCLUSIONS: Overall, our review provided mixed results, which is generally in line with published literature, with most of the studies showing a significant relationship with subclinical CVD, but only some studies failed to demonstrate such an association. Although such mechanistic relationship needs further evaluation in order to determine appropriate screening strategies in vulnerable populations, this review strongly suggested the existence of a relationship between abnormal sleep duration and quality with increased subclinical CVD burden.

Contrast ‐induced encephalopathy following cardiac catheterization
ConclusionsCIE is an important clinical entity to consider in the differential diagnosis of stroke following cardiac catheterization. Given that prognosis is excellent with supportive management only, physicians should be aware of it, and consider it prior to initiating thrombolysis. © 2016 Wiley Periodicals, Inc.

Case Studies Demonstrating Stroke Telemedicine in the Rural Emergency Department
A 65-year-old man was transported to a critical access hospital emergency department for treatment of sudden onset dysphasia, a “funny feeling” on the right side of his face, dysphagia, and difficulty holding water in his mouth. He was alert and oriented and had unremarkable vital signs except for hypertension (188/65 mm Hg). A computed tomography scan of the head identified no abnormalities.

To study the impact of chronic vasodilator therapy on perihematomal edema in primary intracerebral hemorrhage(ICH) (P2.259)
Conclusions:Though limited by small sample size, this retro spective study suggests that chronic vasodilator therapy may serve to prevent worsening cerebral edema. This is a tantalizing finding that, if confirmed, could lead to potential pharmacological interventions for patients with ICH. Further prospective studies evaluating the effect of vasodilators in this patient population will be required.Disclosure: Dr. Singh has nothing to disclose. Dr. Albright has nothing to disclose.

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.

CT perfusion in predicting the morbidity and prognosis of hypoxic-ischemic encephalopathy after off-pump coronary artery bypass grafting.
CONCLUSION: The difference in occipital lobe rTTP on CTA perfusion may be a potential predictor of HIE. Furthermore, abnormal CT and rTTP may be used for predicting the prognosis in HIE patients. Three principal components (F1 as a reflection of CBF, F2 as reflection of TTP, F3 as a reflection of MTT) can be used to generally describe perfusion parameters.

Pericardial, But Not Hepatic, Fat by CT Is Associated With CV Outcomes and Structure: The Multi-Ethnic Study of Atherosclerosis

Hypertension, acute stent thrombosis and paraplegia 6 months after TEVAR for blunt thoracic aortic injury in a 22 year old patient
TEVAR is a less invasive option for managing traumatic injuries of the descending aorta in polytraumatized patients. Concerns arise when treating young patients with TEVAR.A 22-year old male was admitted to the Emergency Department following a high-impact road traffic collision. Whole body CT scan documented multiple injuries, including rupture of descending thoracic aorta just below the isthmus. There was no evidence of paraplegia or stroke. We decided to treat him in an endovascular fashion with a Zenith Cook (Cook Incorporated, Bloomington, IN) endograft.

Symptomatic and silent cerebral infarction following surgical clipping of unruptured intracranial aneurysms: incidence, risk factors, and clinical outcome
In conclusion, the incidence of CI following clipping of UIAs was not low. Larger aneurysm size and history of hypertension were independent risk factors. Postoperative symptomatic str oke correlated with an extremely high risk of disability. Silent CI was seemingly nondisabling, but the possible cognitive consequence is pending.

What is the role of screening for pulmonary hypertension in adults and children with sickle cell disease?
Authors: Willen SM, Gladwin MT Abstract Patient case: An 18-year-old male patient with homozygous hemoglobin SS disease was evaluated for progressive dyspnea and elevated tricuspid regurgitant jet velocity (TRV) on echocardiography. The patient's case is described in detail in Lancet1 He had been treated with regular transfusions since childhood for stroke, had rare episodes of vaso-occlusive pain episodes, and did not take narcotic pain medications. He presented with progressive severe dyspnea on exertion and lower extremity edema. His laboratory tests were notable for a total hemoglobin level of 11.8 g/dL and hem...
