13 Possible Causes for Cortical Venous Thromboses

  • Thrombosis

    The diagnosis of isolated CVT is particularly difficult on the basis of angiographic findings, because the pattern of cortical venous drainage is variable and often asymmetric[ajnr.org] The MR appearance of a thrombosed cerebral vein is dependent on the age of the clot.[ajnr.org]

  • Cerebral Thrombosis

    Cortical veins and collapsed veins may then recirculate, reducing venous congestion and improving venous blood flow in collaterals.[annalsofintensivecare.springeropen.com] venous thrombosis and at the very early stage when T1- and T2- sequences are not sensitive enough. [23] The presence of a hyperintense signal of the thrombosed sinus on diffusion-weighted[annalsofian.org] In addition, it favors anticoagulant to reach the thrombosed venous side [ 8 , 18 ].[annalsofintensivecare.springeropen.com]

  • Cerebral Hemorrhage

    […] or cortical veins within the dura mater covering of the brain.[doi.org] Dural arteriovenous fistulae appear as early venous filling during the arterial phase of contrast injection via direct connections between dural arteries and a venous sinus[doi.org] Aneurysms are visualised on IADSA as contrast‐filled outpouchings that arise from an arterial wall or bifurcation, although thrombosed aneurysms may be more difficult to appreciate[doi.org]

  • Subarachnoid Hemorrhage

    […] or sinus venous thromboses, mycotic aneurysms, or septic emboli with hemorrhagic transformation.[mdcalc.com] […] cases. ( Rosen 2005 ) Points to keep in mind: The scale does not apply to SAH due to trauma, arteriovenous malformations, cavernous angiomas, dural arteriovenous fistulae, cortical[mdcalc.com]

  • Hypertensive Encephalopathy

    thromboses • Spontaneous fetal loss, thrombocytopenia • Infarcts of various sizes and T2 hyperintense WM foci.[neuroradiologycases.com] Neuropsychiatric systemic lupus erythematosus (NPSLE) • Most common: Small multifocal WM lesions • Cortical atrophy, ventricular dilation • Periventricular and diffuse WM[neuroradiologycases.com] Pseudoxanthoma elasticum • Subcortical leukoencephalopathy • Dementia, multiple strokes with hypertension Antiphospholipid antibody syndrome • Early stroke, recurrent arterial and venous[neuroradiologycases.com]

  • Venous Thrombosis

  • Adams-Oliver Syndrome 5

    Abstract In 1945, Adams and Oliver described congenital transverse limb defects associated with aplasia cutis congenita in a three-generation kindred with typical autosomal dominant inheritance and intrafamilial variable expressivity.

  • Intracranial Sinus Thrombosis

    A 68-year-old woman presented with an acute SDH requiring craniotomy and a thrombosed cortical vein was noted intraoperatively.[surgicalneurologyint.com] Isolated cortical venous thrombosis presenting as subarachnoid hemorrhage: A report of three cases.

  • Lateral Sinus Thrombosis

    . • Otitic Hydrocephalus – Due to interrupted cortical venous circulation obstruction in CSF flow leads to ventricular dilatation – One or both lateral sinuses may be found[slideshare.net] Patients with cortical vein thrombosis were also excluded except when the vein afferent to the thrombosed LS was the only cortical vein involved.[stroke.ahajournals.org] thrombosed – S&S of raised ICP 13.[slideshare.net]

  • Cerebral Venous Sinus Disorder

[23] The presence of a hyperintense signal of the thrombosed sinus on diffusion-weighted[annalsofian.org] […] than with T1 (78%) or fluid-attenuated inversion recovery (FLAIR) [2] Therefore, T2*-sequences are of additional value for the diagnosis of CVT, particularly in isolated cortical[annalsofian.org]
