Intracranial hypertension (IH) may be misdiagnosed owing to the lack of typical imaging features and pathological confirmation of the sinus lesions. The authors report the use of percutaneous endovascular biopsy (PEB) for the diagnosis of IH in patients with venous sinus lesions. A total of 9 patients (age 46 ± 9 years) underwent PEB between June 2016 and August 2017. All patients underwent lumbar puncture and contrast-enhanced MRI before the procedure. PEB was technically successful in 6 patients. No intra- or postprocedural complications occurred. The confirmed lesions were meningioma in 2 patients and fibrous thrombus in 4 patients. All patients received individualized treatment. PEB of venous sinus lesions is a safe and efficient method to establish an early diagnosis and appropriate treatment in patients with IH.
