case_images: It showed a 4.6 x 4.3 x 3.9 cm multilocular lesion in the right frontoparietal region with a mass effect on the adjacent lateral ventricle (Figure 1).
case_images: Patohistology finding of the material obtained on surgery (A) Grocott methamine silver staining shows branching microfilamentous bacilli of Nocardia spp. (B) Hematoxylin-eosin staining (magnification 200x): necrotizing granulomas of different sizes with the presence of multi-nuclear Langhans giant cells.

case_images: Silver staining highlighted the filamentous branching rods (Figure 2).
case_images: Timeline of the clinical course. Timelines of hospital admissions, symptoms, events and SARS-CoV-2 testing are labeled from the initial positive RT-PCR test. The Novel Coronavirus (2019-nCoV) Nucleic Acid Diagnostic Kit (PCR-Fluorescence Probing) for the qualitative detection of the ORF1ab and N genes of SARS-CoV-2 RNA was used with Ct value <= 40 considered a positive result.
