We have identified two patients with SCC of the tonsil where the affected tonsil has low signal intensity on T2-weighted MR images and is smaller than the contralateral normal tonsil. We present the {\textquotedblleft}small, dark tonsil{\textquotedblright} as an alternative imaging presentation of SCC and a new sign to look for when evaluating the patient with metastatic lymphadenopathy from an unknown primary tumor.}, issn = {0195-6108}, URL = {https://www.ajnr.org/content/26/2/411}, eprint = {https://www.ajnr.org/content/26/2/411.full.pdf}, journal = {American Journal of Neuroradiology} }
