case_images: An urgent non-enhanced CT scan of the brain and chest, performed on the 24th day of admission, revealed moderately decreased attenuation of the periventricular and semiovale white matter (Figure 1) and severe pneumomediastinum and emphysema, as well as severe diffuse bilateral ground-glass opacities (Figure 2).
case_images: Non-enhanced CT scan of the chest.. A: Lung view showing diffuse bilateral ground-glass opacities (red arrowheads) and pneumomediastinum (red arrows). B: Mediastinal view showing subcutaneous emphysema (yellow arrows).

case_images: First MRI of the brain showing multiple bilateral periventricular and semiovale punctate and oval lesions (white arrows) with surrounding edema that show hyperintensity on T2W images (A, B, C, D, E) and FLAIR images (H, I, J) with diffusion restriction (F, G).. T2W = T2-weighted; FLAIR = fluid-attenuated inversion recovery

case_images: MRI of the brain with angiography/venography, without including the spinal cord, was done on the 28th day of admission (Figure 3).

case_images: Third MRI of the brain showing a decrease in the size of the previous hyperintense lesions (red arrows) on T2W sequences (A, B, C, D, E), diffusion-weighted sequences (F, G), and FLAIR sequences (H, I, J).. T2W = T2-weighted; FLAIR = fluid-attenuated inversion recovery

case_images: The third MRI was done 109 days after the second MRI, which showed a decrease in the size of the previously mentioned lesions, without the development of new lesions (Figure 4).
