Isolated reversible splenial lesion in tick-borne encephalitis: A case report and literature review

EAN consensus review on prevention, diagnosis and management of tick‐borne encephalitis

“…Magnetic resonance imaging findings in the brain include increased signal intensity on T2-weighted and fluid attenuated inversion recovery images in the thalamus, basal ganglia, internal capsule, splenium, cerebellum, peduncles and brainstem [73,74,117,[155][156][157][158][159][160][161][162][163][164][165]. Most common are thalamic lesions that can be unilateral or bilateral, multifocal or more diffuse in character [162].…”

Lesions in the Splenium of the Corpus Callosum on MRI in Children: A Review

“…Typical findings in MS include hyperintense band along the undersurface of the CC, involvement of the callososeptal interface, and ovoid perivenular lesions radiating perpendicular from the ventricular surface known as Dawson's fingers (Fig ) . Breakdown of the blood‐brain barrier in acute demyelination is accompanied by contrast enhancement . Hyperacute demyelinating MS lesions can demonstrate cytotoxic edema on DWI, which mainly corresponds to intramyelinic edema pathologically .…”

Clinical and Neuroimaging Profile of Children with Lesions in the Corpus Callosum

“…A variety of causes including mild encephalitis/encephalopathy with reversible splenial lesion (MERS) have been described with influenza and other viruses as well as with bacterial infections . Most of these patients have isolated splenial lesions.…”
