Endovascular treatment of fulminant idiopathic intracranial hypertension associated with intracranial venous sinus stenosis: one case report

Abstract

Objective To report one case of fulminant idiopathic intracranial hypertension (FIIH) associated with intracranial venous sinus stenosis, and explore its clinical characteristics, diagnostic strategies, and the feasibility and efficacy of endovascular treatment. Methods and Results A 32-year-old female patient presented with progressive headache and rapid visual deterioration. Imaging findings showed optic nerve sheath dilation, posterior globe flattening, and intracranial venous sinus stenosis. Laboratory tests showed iron deficiency anemia, and lumbar puncture showed markedly elevated cerebrospinal fluid (CSF) pressure ( > 330 mmH2O). The clinical diagnosis was FIIH, right transverse sinus stenosis, and iron deficiency anemia. Emergency venous sinus stenting was performed, resulting in a marked reduction in CSF pressure and significant improvement in visual acuity. Conclusions There may be a close association between intracranial venous sinus stenosis and FIIH. Early identification and timely intervention are critical for improving prognosis.
