It was requested a computed tomography (CT) of the cranium without contrast, a magnetic resonance (MRI) and an angioresonance of the cranium. Image 1: Cranial computed tomography (CT) without contrast, axial plane. Image 2: T1-weighted magnetic resonance (MRI) image of the cranium, sagittal plane, after the contrast. Image 3: cranial angioressonance, venous phase, axial and sagittal plane. Question:Based on the clinical history and in the imaging studies presented, it is possible to conclude that the cause of the lesion was: a) Systemic arterial hypertension b) Arteriovenous malformation c) Cerebral Venous Thrombosis d) Brain Tumor Bleeding Time is Up!
