  • Title: Unilateral Basal Ganglia Hyperintensity Secondary to Venous Congestion in a Case of Indirect Carotico-cavernous Fistula.
    Author: Giragani S, Kasireddy AR, Agrawal V, Muthyala S.
    Journal: Neurol India; 2021; 69(4):1048-1050. PubMed ID: 34507443.
    Abstract:
    Intraparenchymal venous congestive changes secondary to carotico-cavernous fistula are not common. Isolated basal ganglia venous congestive changes in carotico-cavernous fistula have been rarely described. We report MRI findings of the unilateral basal ganglia hyperintensity, angiographic features including cortical venous reflux into a variant basal vein of Rosenthal, in a postpartum woman presenting with the left eye proptosis and the right upper limb weakness. We also describe the reversal of imaging findings and resolution of patients' symptoms after definitive treatment of the carotico-cavernous fistula by endovascular embolization.
