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).
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.
