Acute aortic dissection is the most common acute aortic condition requiring urgent surgical therapy. Due to lack of typical symptoms, it is sometimes difficult to identify acute aortic dissection causing ischemic stroke. ⋯ After urgent aortic replacement surgery, the patient recovered with no neurological deficit. This case underscores the crucial role of carotid ultrasonography for the investigation of possible underlying acute aortic dissection when considering the use of intravenous recombinant tissue plasminogen activator therapy for hyperacute stroke.

To evaluate the short-term outcome of erythropoietin (EPO) therapy in rats with spinal cord injury (SCI) using manganese-enhanced magnetic resonance imaging (MEMRI). ⋯ MEMRI successfully depicts the therapeutic effect of EPO in early SCI that leads to a significant recovery in rats, a significantly reduced immune response and significantly reduced number of apoptotic cells at the height of the lesion epicenter.

A 41-year-old woman presented with acute onset headache, vertigo, nausea, and gait disorder, initially interpreted as a common cold. Within 2 weeks, she developed a severe opsoclonus-myoclonus syndrome with truncal ataxia. ⋯ Corresponding PET findings were able to depict the response to therapy in the ocular muscles and the inferior vermis, whereas the deep cerebellar nuclei were still hyperactivated, however, to a lesser extent. This finding highlights the usefulness of functional/metabolic brain imaging to study the pathophysiology of this type of disorder.
