The "small, dark tonsil" in patients presenting with metastatic cervical lymphadenopathy from an unknown primary AMERICAN JOURNAL OF NEURORADIOLOGY Jumper, J. R., Fischbein, N. J., Kaplan, M. J., Klein, H. Z., Dillon, W. P. 2005; 26 (2): 411-413

Abstract

When squamous cell carcinoma (SCC) involves the palatine tonsils, they are generally enlarged and demonstrate intermediate to high signal intensity on T2-weighted MR images and enhance after gadolinium administration. 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 "small, dark tonsil" 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.
