Brain imaging and immunohistochemical results. (A) Rapid progressive damage in the bilateral basal ganglia. Upper: Right basal ganglia lesion with patchy abnormal signals before admission. Lower: The bilateral basal ganglia showed patchy abnormal signals after admission. Bilateral basal ganglia lesions with hemorrhage on the right side. (B) Mixed density shadow in the bilateral basal ganglia with peripheral parenchymal edema and postoperative resection of right basal ganglia lesions. (C) Pathological results from the brain tissues of lesions in the right basal ganglia. Hematoxylin-eosin staining. Fungal spores and hyphae were observed in a small amount of necrotic brain tissue.

Brain magnetic resonance imaging (MRI) showed space-occupying lesions in the right basal ganglia, with obvious local edema (Figure 1A, before admission). MRI showed lesions in the right basal ganglia and frontotemporal lobe, and a new lesion in the left basal ganglia was found (Figure 1A, after admission). Magnetic resonance angiography of the head did not reveal evidence of stenosis or thrombosis of any major intracranial blood vessels. Brain and chest computed tomography (CT) examinations revealed bilateral basal ganglia lesions with a right basal ganglia hemorrhage broken into the ventricle (Figure 1B, left) no abnormalities were found by chest CT. Re-examination of the brain CT showed that brain tissue swelling was more severe than before (Figure 1B, right). Mucor (Figure 1C). Meanwhile, the results of
