Thrombolysis for the treatment of acute ischemic stroke requires careful selection of patients. The authors report a case of aortic dissection presenting with acute ischemic stroke for which emergent ultrasonographic evaluation was helpful in the diagnosis and subsequent treatment. ⋯ Carotid ultrasound revealed right common carotid occlusion that led to the diagnosis of aortic dissection, confirmed by chest computed tomography. An experienced sonographer with skills to perform rapid intra- and extracranial examinations may help to change the treatment plan for acute stroke patients.

Cerebral malaria occurs in 2% of patients infected by Plasmodium falciparum. Magnetic resonance imaging findings of small white matter infarcts due to cerebral malaria have been previously reported, however nonspecific. Since diffusion-weighted imaging can differentiate acute embolic infarcts from other chronic or nonspecific white matter lesions, it may aid diagnosis of this illness in patients who travel to endemic areas.
