    Abstract
  • Objective To explore the diagnostic value of multi-slice spiral CT (MSCT) in nodular goiter with coexistent thyroid carcinoma. Methods CT findings of 25 patients with pathologically-diagnosed nodular goiter associated with thyroid carcinoma were retrospectively analyzed. Results In 3 cases the cancerous lesion was located within the nodular goiter, and in the other 22 cases the nodular goiter and the cancerous lesion existed independently. CT plain scan of 20 cases were obvious low density with a relatively well demarcated margin, and contrast-enhanced CT scanning showed homogeneous or heterogeneous enhancement with poorly defined margin of the lesion, known as " boundary reversion” sign. In 23 cases, the margin of lesion was irregular, and the tumor broke through the capsule, forming the so-called " remnant margin” sign. Calcification within the cancerous lesion was observed in 15 cases, and cervical lymph node metastasis in the ipsilateral neck root or clavicular region was detected in 13 cases. Conclusion The MSCT features of nodular goiter with coexistent thyroid cancer have certain characteristics, using which the comprehensive observation of each nodule can effectively reduce the misdiagnosis of thyroid carcinoma associated with nodular goiter．
