“…The imaging finding of restricted diffusion may reflect a similar pathogenesis to posterior reversible encephalopathy syndrome (PRES) 19 and may not reflect cytotoxic edema (restricted diffusion) from vasogenic edema (no restriction diffusion). 20 The absence of DWI restriction suggests a better prognosis for recovery in PRES (i.e., reversibility), but may not have the same radiographic significance in fulminant IIH or NAION related to papilledema.…”

Posterior reversible encephalopathy syndrome (PRES) is a group of clinical syndromes typically characterized by bilateral reversible vasogenic edema of the subcortical white matter in the parieto-occipital region on neuroimaging that causes a wide variety of acute or subacute neurological symptoms, including headache, mental status alteration, seizures, and visual dysfunction. PRES is classically suspected in patients with severe hypertension, renal failure, autoimmune disorders, eclampsia, or immunosuppressant medications. Frequent neurological evaluations and neuroimaging examinations by computed tomography or magnetic resonance imaging are required for both the diagnosis and assessment of the condition. Early detection of the disease is key for a rapid recovery and good prognosis.

“…Clinical outcome was poorer with increasing severity of edema on T2-weighted imaging and the presence of diffusion restriction. 81,88,89 Like PRES, endothelial dysfunction has been implicated in reversible cerebral vasoconstriction syndrome (RCVS). Two cases of RCVS in SCD patients have been reported in the literature.…”

Sickle cell disease is the most common hereditary hemoglobinopathy, which results in abnormally shaped and rigid red blood cells. These sickle-shaped red blood cells cause vaso-occlusion and ischemic phenomena that can affect any organ in the body. As a common cause of disability, the neurological manifestations of sickle cell disease are particularly important. Neuroimaging has a crucial role in the diagnosis, management, and prevention of the complications of sickle cell disease. These complications can affect the brain parenchyma, vasculature, and skull and can be ascribed directly or indirectly to a vasculopathy of small and large vessels. Vaso-occlusion can cause ischemic stroke. Ischemic damage in the absence of an acute neurological deficit, and therefore only apparent on neuroimaging, is termed silent cerebral ischemia. Weakening of the arterial walls can cause aneurysms. In its most severe form, a vasculopathy of the terminal internal carotid arteries can progress to moyamoya syndrome, characterized by steno-occlusive disease and the formation of friable collateral arteries. Rupture of aneurysms or friable collateral arteries is a potential cause of intracranial hemorrhage. The skull and vertebrae may be affected by extra-medullary hematopoiesis, due to severe anemia, or iron deposition, due to chronic red blood cell transfusion. Impaired blood supply to bone is associated with osteomyelitis and osteonecrosis. Fat embolization syndrome is a rare complication of osteonecrosis, which may cause devastating neurological impairment. Awareness and early recognition of the diverse manifestations of sickle cell disease on neuroimaging is crucial to ensure optimal treatment in a complex patient cohort.
