Abstract

In order to distinguish benign from malignant nodules within the dissected neck area in patients with oral cancer during the follow-up period, we retrospectively evaluated the frequency and characteristic findings of fusiform-shaped nodules along the internal carotid artery observed by follow-up sonography.<br>From 1997 to 2003, 52 patients with oral cancer, who underwent radical neck dissections, were enrolled in this study. The study cohort consisted of 33 males and 19 females ranging in age from 29 to 84 years (mean, 62.0 years). After neck dissection, every patient was examined repeatedly with sonography during the follow-up period at an interval of one month. CT and/or MRI were performed when clinically required. Any patient with recurrent neck mass was excluded from this study. In the 52 patients, fusiform-shaped nodules were observed in 10 patients (19%) by the follow-up sonography. The nodules were homogenously hypoechoic and the margin was well-demarcated except for the upper end. A hyperechoic core was clearly observed in every nodule, which showed a fatty density on post-contrast CT. On post-contrast MRI, the nodules enhanced markedly and the core showed hypointensity on fat saturated images.<br>In conclusion, it was suggested that the fusiform-shaped nodules observed by follow-up sonography within the dissected neck area might be the superior cervical ganglion of sympathetic trunk. However, further studies are needed to disclose the true character of the nodules.
