Mystery Case: A case of oil in ventricles Deception for intraventricular hemorrhage

A 73-year-old woman with history of diabetic retinal detachment surgery 25 years ago in China presented with dizziness, headaches, and syncope. Noncontrast CT head (NCCT) showed hyperdensity within the left lateral temporal horn and fourth ventricle. Next day NCCT and MRI showed a shift of hyperdensity to the right frontal horn (figures 1 and 2).

Impact of the number of metastatic brain lesions on survival after Gamma Knife radiosurgery

Effectiveness of Gamma Knife radiosurgery (GKRS: Elekta AB, Stockholm, Sweden) for patients with metastatic brain disease and the prognostic factors influencing their survival were analyzed in a 5 year retrospective data analysis (July 2001 to June 2006). Kaplan-Meier survival curves were constructed using univariate and multivariate analyses with the respective salient prognostic factors. This study analyzed data on 330 patients with brain metastases who underwent GKRS. Lung carcinoma (55%) was the most common primary cancer followed by breast (17.8%), melanoma (9.4%), colorectal (4.8%) and renal (3.9%). The median survival for all patients was 8 months. Survival ranged from 13 months for breast metastases, 10 months for renal, and 8 months for lung to 5 months for colorectal and melanoma. Mean age of patients was 58.5 years (range 18-81). Melanoma patients were younger with a mean age of 49 and also had the highest number of lesions (3.8) when compared to patients with renal (2.5), lung (2.8), colorectal (3) and breast (3.6). When stratified according to the number of lesions patient survival was 8 months (one to three lesions), 7.5 months (four or five lesions) and 7 months (six lesions or more). Mean Karnofsky Performance Status score (KPS) was 77 and survival dropped significantly from 8 months to 4.5 months if KPS was less than 70. Survival improved with a KPS of 70 or more, regardless of the number of lesions treated. Selection of patients based on the number of lesions may not be justified. A prospective trial is required to further define the prognostic factors affecting survival.

Spanning from the West to East: An Updated Review on Endovascular Treatment of Intracranial Atherosclerotic Disease

Ischemic stroke is a major cause of morbidity and mortality, incurring significant cost. Intracranial atherosclerotic disease (ICAD) accounts for 10-15% of ischemic stroke in Western societies, but is an underlying pathology in up to 54% of ischemic strokes in Asian populations. ICAD has largely been treated with medical management, although a few studies have examined outcomes following endovascular treatment. Our objective was to summarize the major trials that have been performed thus far in regard to the endovascular treatment of ICAD and to provide direction for future management of this disease process. Systematic review of the literature from 1966 to 2015, was conducted in regard to intracranial angioplasty and stenting. Studies were analyzed from PubMed, American Heart Association and Society of Neurointerventional Surgery databases. SAMMPRIS and VISSIT are the only randomized controlled trials from which Western guidelines of intracranial stenting have been derived, which have displayed the superiority of medical management. However, pooled reviews of smaller studies and other nonrandomized trials have shown better outcomes with endovascular therapy in select patient subsets, such as intracranial vertebrobasilar stenosis or in the presence of robust collaterals. Suboptimal cases, including longer lesions, bifurcations and significant tortuosity tend to fair better with medical management. Medical management has been shown to be more efficacious with less adverse outcomes than endovascular therapy. However, the majority of studies on endovascular management included a diverse patient population without ideal selection criteria, resulting in higher adverse outcomes. Population analyses and selective utilization of endovascular therapy have shown that the treatment may be superior to other management in select patients.

Cervical spine epidural abscess: a single center analytical comparison to the literature.

Study Design:Retrospective review of patient charts.Objectives:Cervical spine epidural abscess (CSEA) is uncommon. In this study, characteristics of CSEA patients are described through an institutional analysis and literature review.Setting:University-affiliated city hospital.Methods:The electronic medical record was searched from 01/2001 to 01/2012. Data on presentation, comorbidities, diagnostic modalities, pathogens, treatments, and neurological recovery were collected.Results:Sixteen patients were identified with a mean age of 57.9 years (33-83). Nine were females. Common symptoms were neck/back pain (62.5%), neurological deficits (62.5%), and fever (31.3%). Comorbidities included cardiovascular disease (56.3%), renal disease (37.5%), and diabetes mellitus (37.5%). Lower levels were more likely afflicted (C5-C7). Microorganisms were commonly Staphylococcus and Streptococcus (68.8%). Eight (50.0%) received surgery (anterior [87.5%] and posterior [12.5%] cervical fusion and corpectomy [37.5%]) plus antibiotics and 8 (50.0%) were treated with antibiotics only. Patients with less comorbidities were more likely to receive surgery; more comorbidities were was associated with a poor prognosis. Eight patients (50%) made had full neurological recovery, 2 (12.5%) with had minimal recovery, 2 deaths died, and the remaining (25%) 1 was were sent to a skilled facility and 1or lost to follow-up.Conclusions:Cervical SEA can be problematic. The vast majority do not present classically and treatment does vary. It occurs more frequently in the lower cervical levels. Though antibiotics alone may suffice, surgery is frequently employed and a multitude of techniques are at the utility of the spine surgeon. Cardiovascular comorbidities are associated with a poorer outcome. In order to improve prognosis, management considerations should include both patient factors and multidisciplinary efforts.
