bithalamic infarction

Bitalamic

infarction related to occlusion of Percheron artery in patient with patent foramen-ovale. Axial DWI sequence at the same level shows two areas of restricted diffusion signal in both medial thalami.

Bitalamic

infarction related to occlusion of Percheron artery in patient with patent foramen-ovale. Axial DWI: increasing restriction of the signal in the thalamic regions.

Bitalamic

infarction related to occlusion of Percheron artery in patient with patent foramen-ovale. Axial T2 FLAIR: two areas of hyperintensity in the thalamic regions due to the beginning of vasogenic oedema.

Bitalamic

infarction related to occlusion of Percheron artery in patient with patent foramen-ovale. Axial CT shows a well-defined hypodense lesion in the left thalamus and a smaller subtle area of hypodensity in the right thalamus. These findings are consistent with a subacute evolution of stroke.

Bithalamic

venous infarction due to straight sinus thrombosis. NECT demonstrates hypodensity of both basal ganglia regions of poorly defined borders, mainly affecting both thalami (a and b). Doubtful spontaneous hyperdensity in the region corresponding to internal cerebral veins (b).

Bithalamic

venous infarction due to straight sinus thrombosis. Axial FLAIR acquisition. Bithalamic hyperintensity.

Bithalamic

venous infarction due to straight sinus thrombosis. MRI venous-phase angiography MIP in sagittal view. Lack of visualization of straight sinus, inferior sagittal sinus, Galen"s vein and internal cerebral veins.

Bithalamic

venous infarction due to straight sinus thrombosis. DWI shows minimal areas of restricted diffusion in bithalamic regions.

Bithalamic

venous infarction due to straight sinus thrombosis. Axial T2W FFE. Bithalamic hyperintensity. Small punctate markedly hypointense lesions, representing foci of cerebral microhaemorrhage.
