Figure 1: (a) Axial head computed tomography demonstration enlargement of the right frontal sinus with thinned and almost dehiscent overlying bone (arrowheads), without breakthrough of the cortex. (b) Axial T2-weighted image with a high internal signal intensity (arrow) and surrounding hypointense rim (asterisk). (c) Axial T1-weighted image demonstrating high internal signal intensity, with intermediate signal of surrounding tissue. (d) Axial gadolinium-enhanced T1-weighted image shows faint peripheral enhancement.
