Abstract

Cerebral venous thrombosis is not a frequent condition and may follow unsuspected, with unspecific manifestations. Neuroimaging studies are mandatory in differential diagnosis, which includes arterial strokes and other benign and malignant causes of intracranial hypertension, headaches, seizures, and hemiparesis. Characteristic images are triangle and the empty delta signs, and loss of flow void. Images of total or partial empty sella can be associated with secondary or idiopathic intracranial hypertension. Primary type occurs in up to 35% of cases, mainly affecting middle aged obese and hypertensive women. Membranous subaortic stenosis is a congenital or acquired change of the left ventricular outflow tract, with connections to the aortic and mitral valves; aortic regurgitation usually develops. Partial empty sella, sagittal sinus thrombosis and membranous subaortic stenosis are herein described in an obese woman, aiming to enhance the interest for new studies to better clear the possibility of some causal relationship among them.
