Aspirin is once again in the headlines, prompted by New England Journal of Medicine reports suggesting that people aged 70 years and older obtain no benefit and perhaps experience harm in the form of increased bleeding and increased death from cancer on low-dose aspirin. This adds to the decades-long debate on whether aspirin is beneficial as a preventive measure against cardiovascular events such as heart attack in which a blood clot forms on top of inflamed atherosclerotic plaque in the coronary arteries. Unlike many other studies that are observational and therefore virtually useless, these studies are prospective and r...
CONCLUSION: Our experience shows that GKS performed in conjunction with our targeting technique safely and effectively treats hemorrhagic MBTs. The success of this technique may reflect the presence of scattered metastatic tumor cells in the hematoma that do not proliferate owing to the inadequate microenvironment of the hematoma. We suggest that GKS can be a useful treatment option for patients with hemorrhagic MBTs that are not amenable to surgery. PMID: 30196656 [PubMed]
We report a case of RCVS with hidden breast cancer in which ischemic stroke and cortical subarachnoid hemorrhage were observed earlier than vasoconstriction, and there were positive autoantibodies.
This article provides insight into current anesthesia procedures. These include clinical cases of elective tumor resection to wake craniotomy. Furthermore this review covers emergencies with acute intracranial pressure increase and intracranial hemorrhage. PMID: 30176689 [PubMed - in process]
Glioblastoma is the most common primary malignant tumor of the brain. Common radiological findings using initial computed tomography (CT) reveal an intra-axial lesion with perifocal edema. Here we present a rare case of diffuse subarachnoid hemorrhage (SAH) detected on an initial CT image in a patient without intracranial aneurysm in whom the final diagnosis was glioblastoma.
Sankarsh N Jetty, Zain Badar, Douglas Drumsla, Rajiv ManglaJournal of Clinical Imaging Science 2018 8(1):36-36 Superficial siderosis is the slow accumulation of hemosiderin on the pial surfaces of the brain and spinal cord. The most common cause of intracranial superficial siderosis is secondary to subarachnoid hemorrhage. Rarely, superficial siderosis can also be caused by tumors. Superficial siderosis presents clinically as hearing loss and gait instability that progressively worsen. The diagnosis is primarily made by magnetic resonance imaging; however, susceptibility-weighted imaging (SWI) and T2* gradient echo (G...

CONCLUSION: Decreased neuroinflammation and reduced BBB leakage may contribute, at least in part, to vasculotide-induced neuroprotective effects after stroke in T1DM rats. PMID: 30124060 [PubMed - as supplied by publisher]
CONCLUSION: in this case report FCH PET/CT represented the final diagnostic technique to confirm the suspicious of a cystic GBM. Our case demonstrated the potential role of 18F-FCH PET/CT for discrimination of higher proliferation area over intraparenchymal hemorrage, supporting the potential use of this imaging biomarker in surgical or radiosurgical approach. Obviously, further prospective studies are needed to confirm this role and to exactly define possible routinely applications. PMID: 30117406 [PubMed - as supplied by publisher]
Conclusion: Although small foci of metastatic disease as a source of bleeding for some patients cannot be excluded, melanoma patients with a suspected hemorrhagic brain metastasis that shows no tumor cells on pathology may benefit from close observation. The local recurrence risk in such cases appears to be low, even without adjuvant radiation. PMID: 30105140 [PubMed]
