Figure.2: Thoracic computed tomography showing diffuse bilateral pulmonary infiltrates. Ground-glass opacity of uncertain cause is present.
There were no abdominal or pelvic abnormalities upon initial imaging workup, and a plain CT scan of the brain was unremarkable, with no ischemia or hemorrhage. (Fig.3) On the third day of admission, emergency magnetic resonance imaging (MRI) Brain revealed extensive bilateral symmetrical punctate foci of nearly the same size with abnormal signal intensities. These foci affect the cerebral hemispheres with restricted diffusion, decreased signals in susceptibility-weighted imaging (SWI) indicative of microbleeds, and mottled fluid-attenuated inversion recovery (FLAIR) signals.
