Cerebral cortical restricted diffusion or gyriform restricted diffusion refers to curvilinear hyperintense signal involving the cerebral cortex on DWI images with a corresponding low signal on ADC images.

Causes include the following disorders:

Vascular thrombo-occlusive disease (most common) ¹

Hemodynamic changes

hypoxic-ischemic encephalopathy
status epilepticus
- acute febrile status epilepticus ³
post-ictal changes
reversible cerebral vasoconstriction syndrome (RCVS) ⁵

Infections

Metabolic

hypoglycemic encephalopathy
hepatic encephalopathy
urea cycle disorders ⁵
Posterior Reversible Encephalopathy Syndrome (PRES) ⁵

Others

MELAS or other mitochondrial encephalopathy disorders
electrocution ⁴

An acronym has been proposed to cover most of these disorders, which is "CRUMPLED" (Creutzfeldt-Jakob, Reversible cerebral vasoconstriction syndrome, Urea cycle disorders, Mitochondrial, Posterior reversible encephalopathy, Prolonged seizures, Laminar necrosis/hypoxic-ischemic encephalopathy, Liver Disease, Encephalitis, and Diabetes) ⁵.
