Figure 1. Axial sequences of an MRI brain with and without contrast, demonstrating a rim-enhancing lesion in the suprasellar cistern with restricted diffusion, indicated by red arrows (case 1). MRI: magnetic resonance imaging.
Figure 2. MRI brain with and without contrast showing (a) leptomeningeal enhancement most prominent along the ventral margin of the brainstem and perimesencephalic cisterns, indicated by the red arrow. Images (b) and (c) depict hyperintensity along the cervical and thoracic spine, indicated by red arrows (case 2). MRI: magnetic resonance imaging.
Figure 3. Hematoxylin and eosin (H&E) stained photomicrograph showing a necrotizing granuloma with a central necrosis surrounded by lymphocytes, epithelioid histiocytes and giant cell (asterisk). Inset shows septate fungal hyphae on a GMS special stain.
