Although not all patients with tinnitus require imaging, patients with tinnitus and asymmetric hearing loss, additional neurologic findings, or pulsatile tinnitus should be evaluated with an appropriately tailored imaging study. Choice of imaging study should be guided by type of hearing loss and additional physical examination findings, such as middle ear lesion, presence of carotid bruit, or pulsatile tinnitus extinguished by jugular compression.

ReviewClinical Distinction of Cerebral Ischemia and Triaging of Patients in the Emergency Department: Mimics, Wake-ups, Late Strokes, and Chameleons.
Non-stroke conditions may present in ways suggestive of ischemic stroke (ie, stroke mimic). Alternatively, the clinical presentation of ischemic stroke can vary considerably and may appear similar to another condition (ie, stroke chameleon). Common and uncommon mimics and chameleons are presented with discussion of key considerations to improve diagnostic accuracy.

Given the need for early restoration of blood flow and preservation of partially damaged brain cells after ischemic stroke, the noninterventional treatment of stroke relies heavily on the speedy recognition and classification of the clinical syndrome. Initiation of systemic thrombolysis with careful observation of contraindications within the 3.0 (4.5)-hour time window is the approved therapy of choice. Management of hemorrhagic complications and resumption of oral anticoagulation if indicated are also discussed in this article.
