There is a space-occupying lesion situated at the right parietal lobe. It has an irregular border that is low signal on T2 images. The center of the lesion is intermediate on T1 and hyperintense on T2 images. The lesion is surrounded by voluminous vasogenic edema that distorts and expands the lobe and results in brain structures shift into the contralateral side. On the ADC map, the lesion shows diffusion restriction due to a center of viscous pus. On the post-contrast images, the lesion shows wall enhancement in the so called ring pattern.
Changes of sinusitis are also seen in the left maxillary sinus.
