case_images: Computerized tomography of the head [Figure 1] showed left extra-axial parietooccipital focal hypoattenuation with adjacent bone erosion.
case_images: Brain magnetic resonance imaging sequences. In a (green circle), T2 weighted. In b (red circle), fluid attenuation imaging recovery acquisition (FLAIR). In c (yellow circle), diffusion-weighted sequence (DWI). In d (blue circle), gadolinium-enhanced T1 acquisition. One can see left parietooccipital subdural collection well demarked with hypersignal in T2 and intermediate signal in T2/FLAIR with water restriction to diffusion in DWI and peripheral enhancement after contrast.

case_images: Brain MRI [Figure 2] reported left parietooccipital subdural collection associated with focal leptomeningeal thickening.
case_images: Left parietooccipital dura mater biopsy. In a, noncaseous granuloma with multinucleated giant cells. In b, silver stain showing rounded birefringent structures consistent with paracoccidioidomycosis (circle).

case_images: The adjacent dura mater was resected showing noncaseous granuloma with multinucleated giant cells and asteroids bodies on histopathology [Figure 3].
