Lentiform fork sign (basal ganglia)
Lentiform
fork sign in a uremic patient with a high anion gap metabolic acidosis with seizures: a case report from North West of Ireland. Showing CT Scan and MRI Brain images. a CT-brain showing bilateral symmetrical hypodensity in the basal ganglia. b MRI Brain axial FLAIR sequence. c MRI brain coronal T2 sequences both showing bilateral symmetrical swollen lentiform nuclei with a hyperintense T2/FLAIR signal rim delineating the boundaries of the putamen
The lentiform fork sign has been described on MRI and is seen as bilateral symmetrical hyperintensities in the basal ganglia surrounded by a hyperintense rim delineating the lentiform nucleus.
It has been postulated to result from metabolic acidosis due to any cause, e.g. end stage renal disease.
