  • Title: Role of Imaging in pseudotumor cerebri syndrome.
    Author: Veiga-Canuto D, Carreres-Polo J.
    Journal: Radiologia (Engl Ed); 2020; 62(5):400-410. PubMed ID: 32736880.
    Abstract:
    Pseudotumor cerebri is a disorder characterized by increased intracranial pressure that predominantly affects obese young women. This paper aims to define the concepts of primary pseudotumor cerebri, in which the cause cannot be identified (also known as idiopathic intracranial hypertension), and secondary pseudotumor cerebri, in which the cause can be identified. We review the current role of imaging techniques in diagnosing pseudotumor cerebri and describe and illustrate the most characteristic imaging findings of the disorder, some of which are included in the diagnostic criteria proposed in 2013. We also consider the fundamental role of interventional radiology in the treatment of pseudotumor cerebri because placing a stent in stenosed venous sinuses is a novel treatment option in patients who are refractory to classical treatment. Finally, we describe the imaging biomarkers that have been evaluated for diagnosing primary pseudotumor cerebri and predicting the response to treatment.
