Pseudotumor artifact of the dorsum sella in CT scanning.
Misinterpretation of CT scans in the skull base can result from artifacts due to abrupt density variations of anatomical structure. In this report a wide dorsum sella with low attenuation medullary cavity was initially mistaken on axial scans for an enhancing suprasellar mass. The correct diagnosis was made with follow-up scans based upon thinner cuts, slice angulation negative to the baseline, and reconstructed coronal and sagittal images.
