Abstract Pseudotumor cerebri is a disorder characterised 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. El síndrome de pseudotumor cerebral (SPTC) es una alteración caracterizada por el aumento de presión intracraneal que afecta predominantemente a mujeres jóvenes obesas. El objetivo del trabajo es definir los conceptos de SPTC primario, sin causa identificable y denominado también hipertensión intracraneal idiopática (HII), y de SPTC secundario, con etiología identificable. Se revisa el papel actual de las pruebas de imagen en su diagnóstico y los hallazgos por imagen típicos del SPTC, algunos de los cuales se incluyen entre los criterios diagnósticos propuestos en 2013. También se remarca el papel fundamental de la radiología intervencionista en el tratamiento, puesto que la colocación de stent en las estenosis de senos venosos constituye una alternativa terapéutica novedosa en pacientes resistentes al tratamiento clásico. Por último, se describen aquellos biomarcadores de imagen que han sido evaluados para aproximar el diagnóstico de la HII y predecir la respuesta al tratamiento.
