Sudden onset of weakness.
Patient Data
Age: 75 years
Gender: Male
From the case:
Stroke window
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/95768/annotated_viewer_json?lang=us"}
Left precentral gyrus grey-white matter loss is most easily seen on narrow "stroke" window (W40, C40)
From the case:
Stroke window
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/95769/annotated_viewer_json?lang=us"}
Diffusion-weighted imaging obtained later that day confirms the presence of a precentral gyrus infarct.
Case Discussion
This case demonstrates the utility of a stroke window that accentuates the difference between grey and white matter.
