Microscopic findings and imaging results for patient with HIV-induced immunodeficiency preceding diagnosis of neurosarcocystosis, Norway. A) Light microscopic findings of structures resembling Toxoplasma gondii bradozoites (white arrows) in brain biopsy. Hematoxylin and eosin stain. Scale bars of enlarged images indicate 50 μm; scale bar of background image indicates 100 μm. B) Magnetic resonance imaging of cerebral and spinal cord lesions (contrast enhanced sagtittal T1 sequence, left panel, red arrows) and cerebral lesions with slight peripheral ring enhancement (contrast enhanced transversal T1 sequence, right panel, red arrows).
