Report of intradural aneurysm in the cavernous segment of the internal carotid artery presented with subarachnoid hemorrhage and oculomotor palsy.

Conclusion: Intradural rupture of proximal cavernous segment carotid aneurysms is rare. We review the literate for such cases and discuss the possible causes. PMID: 32637202 [PubMed]

CONCLUSIONS: Our two cases demonstrate that the listeriosis outbreak should change the way we view bacterial meningitis in SA: according to the National Institute for Communicable Diseases, empirical treatment for meningitis should include ampicillin and gentamicin in all adult patients with features of meningitis. There may be a need for an updated meningitis treatment guideline in SA. PMID: 31131793 [PubMed - in process]

Authors: Yang CW, Fuh JL Abstract INTRODUCTION: Thunderclap headache (TCH) is an excruciating headache that reaches maximal intensity within a minute. It has numerous potential etiologies, the most concerning of which is subarachnoid hemorrhage (SAH) due to high morbidity and mortality. Thus, patients with TCH must be evaluated urgently to identify the underlying cause and initiate prompt therapy. Areas covered: This paper reviews PubMed-listed research articles and presents an update of the clinical features, diagnostic evaluation, and possible causes of TCH. Expert commentary: In addition to SAH, TCH has been associ...

Publication date: Available online 23 August 2018Source: Annals of Emergency MedicineAuthor(s): Mario A. Camacho, Jeff Druck, Martin MusiA 22-year-old man with a history of intravenous methamphetamine use presented with severe headache for 5 days, was afebrile, and had nuchal rigidity. Computed tomography and magnetic resonance imaging results were interpreted as revealing acute subarachnoid hemorrhage. Twenty-four hours later, he developed acute neurologic deterioration. A lumbar puncture was performed, revealing the presence of Staphylococcus aureus. The false-positive image mimicking blood was potentially a result of an...

The purpose of the Research to Practice column is to review current primary journal articles that directly affect the practice of the advanced practice nurse (APN) in the emergency department. This review examines the findings of Carpenter et al. (2016) from their article, “Spontaneous Subarachnoid Hemorrhage: A Systematic Review and Meta-Analysis Describing the Diagnostic Accuracy of History, Physical Exam, Imaging, and Lumbar Puncture With an Exploration of Test Thresholds.” The authors concluded that although no history or physical examination finding can be used to rule in or rule out spontaneous subarachno...

Conclusions: LP in our cohort of neurologically intact CT-negative ED headache patients did not identify any cases of aneurysmal SAH but was associated with serious complications, a significant false positive rate, and extended ED length of stay. PMID: 29599652 [PubMed - in process]

Abstract Subarachnoid hemorrhage (SAH) is a neurologic emergency due to bleeding into the subarachnoid space. Mortality can reach 50%. The clinical presentation is most often in the form of headache, classically defined as maximal at onset and worst of life. The most common cause is traumatic; approximately 80% of nontraumatic SAH are due to aneurysmal rupture, with the remainder from idiopathic peri-mesencephalic hemorrhage or other less common causes. Noncontrast brain computed tomography (CT) performed within 6 hours of symptom onset has sensitivity approaching 100%. Lumbar puncture may be considered after...

We describe a patient in whom transverse sinus thrombosis preceded intracranial venous hypertension and PNSAH. These findings supported that the source of the subarachnoid hemorrhage is venous in origin. Patient concerns and diagnoses: A 45-year-old right-handed man was admitted to the hospital with a sudden onset of severe headache associated with nausea, vomiting, and mild photophobia for 6 hours. The patient was fully conscious and totally alert. An emergency brain computed tomography (CT) revealed an acute subarachnoid hemorrhage restricted to the perimesencephalic cisterns. CT angiography revealed no evidence of an...

Sentinel headache (SH) is estimated to occur prior to rupture of an aneurysm in 15-60% of aneurysmal subarachnoid hemorrhage (aSAH) cases. Non-contrasted computed tomography (CT) of brain and lumbar puncture are both negative, by definition, in patients presenting with SH. One of the theories explaining this phenomenon is micro-hemorrhage (MH) from the aneurysm wall contributing to iron deposition in the interface between the aneurysm wall and brain parenchyma. Quantitative susceptibility mapping (QSM) is a recently introduced magnetic resonance imaging (MRI) technique that has been shown capable of localizing the depositi...

The objective of this study was to describe demographic and clinical characteristics including features that were consistent with subarachnoid hemorrhage (SAH), use of diagnostic tests, emergency department (ED) discharge diagnoses, and disposition of adult patients presenting with an acute headache to EDs statewide across Queensland, Australia. In addition, potential variations in the presentation and diagnostic workup between principal‐referral and city‐regional hospitals were examined. MethodsA prospective cross‐sectional study was conducted over 4 weeks in September 2014. All patients ≥ 18 years presentin...
