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 1, e.g. end stage renal disease.
