1 Coronal (A) and axial (B) noncontrast CT scans of the paranasal sinuses show an air cell within the intersinus septum. Coronal (A) and axial (B) noncontrast CT scans of the paranasal sinuses show an air cell within the intersinus septum. On the coronal image, the cell seems to arise within the septum. However, on the axial image the cell is seen to be a diverticulum from the right frontal sinus. P.M. Som, and W. Lawson AJNR Am J Neuroradiol 2008;29: ©2008 by American Society of Neuroradiology
