Cerebral cortical restricted diffusion, also known as gyriform restricted diffusion, cortical ribboning or cortical ribbon sign, 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)

Haemodynamic changes

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

Infections

Metabolic

hypoglycaemic 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-ischaemic encephalopathy, Liver Disease, Encephalitis, and Diabetes) ⁵.
