Show the Sinus Infection                         Show the Meningeal Enhancement                        Show the Subdural Collections

Axial (left and middle) and coronal (right) T1-weighted with gadolinium MRI scans. Note the prominent enhancement in the frontal sinus, and the collection in the subdural space with surrounding enhancement. Aspiration of the subdural collection demonstrated frankly purulent material, in this case resulting from direct spread from the frontal sinus.
