a–n Timeline of patient: representative images. Representative images from April 2017 (7 months after resection of atrial myxoma) with fluid-attenuated inversion recovery (a, b) and gradient recalled echo sequences (c, d) showing small hemorrhagic lesions throughout the bilateral frontal, parietal, and occipital lobes. Follow-up imaging from October 2017 shows interval increase in size of numerous lesions on fluid-attenuated inversion recovery (e, f) and susceptibility weighted imaging (g, h). i (right internal carotid artery) and j (left internal carotid artery) are representative images from cerebral angiogram done in October 2017, demonstrating multiple mycotic aneurysms. Fluid-attenuated inversion recovery (k, l) and susceptibility weighted imaging (m, n) sequences from repeat magnetic resonance imaging of the brain in March 2018 (post-radiation)
