Findings
- T2/FLAIR signal hyperintensity in the right precentral gyrus (including the hand motor knob) and extending slightly into the postcentral gyrus with blurring of the gray-white interface
- Band of T2/FLAIR signal hyperintensity bridging this abnormal cortex and the ventricular ependymal margin
- No substantial gyral expansion or intracranial mass effect
Annotated Images & Illustrations
Abnormal cortical thickening and T2/FLAIR signal hyperintensity (red arrow) with blurring of the gray-white junction and a band of T2/FLAIR signal hyperintensity extending to the underlying ventricular margin (yellow arrow).
Diagnosis
