Reversible delayed post-hypoxic leukoencephalopathy

Reversible delayed posthypoxic leukoencephalopathy.

Hypoxic ischemic encephalopathy may cause early deep white matter abnormalities on MR imaging that usually progress to include gray matter and basal ganglia change. Toxic leukoencephalopathy due to heroin inhalation predominantly causes cerebellar and posterior cerebral radiologic change. Both conditions rarely present clinically and radiologically in a delayed manner with subsequent recovery. ...

Injury of ascending reticular activating system associated with delayed post-hypoxic leukoencephalopathy: a case report

BACKGROUND Delayed post-hypoxic leukoencephalopathy (DPHL) is a demyelinating syndrome characterized by neurological relapse after an initial recovery from hypoxic brain injury. We describe a patient with impaired consciousness following DPHL, concurrent with injury of the ascending reticular activating system (ARAS) shown using diffusion tensor tractography (DTT). CASE PRESENTATION A 50-year...

Delayed Post-Hypoxic Leukoencephalopathy: Case Report with a Review of Disease Pathophysiology

Delayed post-hypoxic leukoencephalopathy is a rare clinical phenomenon usually observed in a small number of carbon monoxide poisoning survivors. A similar phenomenon is reported here in a patient who successfully recovered from a large overdose of diazepam and methadone, but then abruptly declined 3 weeks after the initial event. Magnetic resnance revealed confluent white matter hyperintensity...

Delayed tacrolimus leukoencephalopathy, a rare and reversible cause of dementia

The immunosuppressant tacrolimus (FK506) is widely used in transplantation medicine. An acute leukoencephalopathy with clinical and radiologic features similar to posterior reversible encephalopathy syndrome (PRES) is a common side effect of tacrolimus, and usually develops within the first year of commencing treatment, but a delayed and chronic leukoencephalopathy has been reported rarely in t...
