To the Editor: We read with great interest the case report titled “Recurrent sebaceous carcinoma of the eyelid: Outcome after postoperative reirradiation” authored by Puja Sahai published in the January 2016 issue of Head & Neck. In this case report, “(a) 38-year-old man . . . diagnosed with sebaceous carcinoma of the right lower eyelid” was described. Herein, we seek a correction, in case your readers may be misled by the 2 important technical problems. It is significant that the image that was presented in Figure 2A as a non–contrast-enhanced CT is indeed a contrastenhanced CT image. The hyperdense appearance of the basilar artery, extraocular muscle groups, and cavernous sinus are the evidence that this procedure is done by giving contrast material. In consideration of these data, the image presented as a non–contrast-enhanced CT in Figure 2A should be changed to a contrast-enhanced CT. Not having a radiologist among the researchers may have caused this mistake. Aside from this, there is another technical problem that should also be corrected. While examining a lesion to determine whether it is contrast-enhanced or non–contrastenhanced, the researchers have to examine the images of a contrast-enhanced CT and a non–contrast-enhanced CT together. The mass presented in Figure 2B is identified as a contrast-enhanced lesion, but the noncontrast images are not presented. We thought that this mistake is another wrong message given to the readers, most of whom are not radiologists. In order to examine whether a lesion is contrast enhanced or not, both contrast-enhanced CT images and non– contrast-enhanced CT images of the same location have to be presented together.
