Uremic Encephalopathy Presented as Stroke: The Value of Lentiform Fork Sign.

Uremic encephalopathy (UE) is a neurological complication of renal failure characterized by cognitive dysfunction and movement abnormalities. A novel radiologic sign termed the "lentiform fork sign" has been identified in patients with UE and metabolic acidosis. This sign manifests as bilateral symmetrical hyperintensities in the basal ganglia, bordered by a hyperintense rim on magnetic resonance imaging (MRI), particularly on T2-weighted and fluid-attenuated inversion recovery (FLAIR) sequences.
