Conclusion :
The lentiform fork sign is a pathognomonic MRI finding for uremic encephalopthay, especially when it’s associated with extrapyramidal movements. It is of great importance to recognize and treat movement disorders in patients with ESRD and dialysis, and physicians should keep in mind the effect of metabolic disturbances on the neurotransmitters of the brain, and must always consider the adverse reaction of the prescribed drugs (such as haloperidol) and their impact on their patients.
