DOI: https://doi.org/10.21980/J8CH05 Issue 3:1 No ratings yet.

A non-contrast CT (Figure 1) revealed a large hypoattenuating left parietal lesion. When the CT was enhanced with intravenous contrast (Figure 2), the same lesion showed peripheral rim enhancement, suggestive of a brain abscess.

A non-contrast computed tomography (CT) scan showed a hyperdensity along the right middle cerebral artery (MCA) consistent with acute thrombus. The red arrow highlights the hyperdensity in the annotated image.

At the end of this simulation session, the learner will: 1) Demonstrate the management of status epilepticus 2) Justify when airway intervention is needed for status epilepticus 3) Describe risk factors for status epilepticus 4) Prepare a differential diagnosis for the causes in status epilepticus.

Presentation of Significant Subarachnoid Hemorrhage without Loss of Consciousness

Nicholas Taylor, BA^* and Shannon Toohey, MD, MAEd^*

DOI: https://doi.org/10.21980/J80W29 Issue 2:2 No ratings yet.

A non-contrast head CT demonstrated extensive subarachnoid hemorrhage occupying both cerebral convexities, the anterior interhemispheric fissure, the sylvian fissures, and the basal cisterns. Later CTA would show an 8 mm by 7 mm by 8mm MCA aneurysm near the M1/M2 junction and two pericallosal artery aneurysms, 7 by 6 mm and 8 by 5 mm respectively.

Non-contrast Computed Tomography (CT) of the Head showed a dense extra-axial collection along the left frontal and parietal regions, extending superior to the vertex with mild mass effect, but no midline shift.

Intracranial Hemorrhage Following a 3-week Headache

John Jiao, MHS^* and Alisa Wray, MD^*

DOI: https://doi.org/10.21980/J89885 Issue 2:1 No ratings yet.

The patient’s head CT showed a significant area of hyperdensity consistent with an intracranial hemorrhage located within the left frontal parietal lobe (red arrow). Additionally, there is rightward midline shift up to 1.1cm (green arrow) and entrapment of the right lateral ventricle (blue arrow).

Approach to Acute Headache: A Flipped Classroom Module for Emergency Medicine Trainees

Jeff Riddell, MD^*, Stacy Sawtelle, MD^{^}, Paul Jhun, MD^‡, James Comes, MD^{^}, Ramin Tabatabai, MD^~, Daniel Joseph, MD^~, Jan Shoenberger, MD^~, Esther Chen, MD^‡, Christopher Fee, MD^‡, and Stuart Swadron, MD^~

DOI: https://doi.org/10.21980/J8WC73Issue 1:1 No ratings yet.

At the end of this module, the learner will be able to: 1) list the diagnoses critical to the emergency physician that may present with headache; 2) identify key historical and examination findings that help differentiate primary (benign) from secondary (serious) causes of headache; 3) discuss the indications for diagnostic imaging, lumbar puncture and laboratory testing in patients with headache; 4) recognize life-threatening diagnoses on CT imaging and CSF examination; 5) describe treatment strategies to relieve headache symptoms.
