摘　　要：目的探讨下颌下腺结石CT图像特点。方法对其CT图片及临床资料进行整理分析。结果共发现26例下颌下腺结石,发生率（26/2000=1.3%）;共发现结石44枚,其中单发结石16例（16/26=61.5%）,多发结石10例（10/26=38.5%）,22例（22/26=84.6%）合并颌下腺炎,结石大小4.65±0.86（0.8~12mm）,年龄15~72岁,平均年龄（36.6±6.5）岁,男18例（18/26=69.2%）,女8例（8/26=30.8%）;11例呈圆形（11/44=25.0%）,28例呈椭圆形（28/44=63.6%）;5例不规则形（5/44=11.4%）。CT表现为沿下颌下腺导管方向走行的大小不等,形态不一的高密度影,同时伴有同侧下颌下腺腺体增大,密度欠均等改变,增强扫描后结石未见强化。结论下颌下腺结石的CT表现具有特征性,结合临床表现对该病做出明确诊断。Objective The purpose of this study was to assess the characteristics of Submandibular duct calculi as revealed by computed tomography image（ CT） studies. Methods We retrospectively reviewed CT of the Submandibular in 2000 consecutive subjects who ranged in age from 15 to 82 years（ mean,52. 3 ± 7. 8 years）. The CT images,clinical data of Submandibular duct calculi were assessed. All were used Toshiba 640-slice spiral CT. Results Submandibular duct calculi were found in 26 patients（ 26 /2000 = 1. 3%） who ranged in age from 15 to 72 years（ mean,36. 6 ± 6. 5） years. 44 calculi were found in 26 patients including single calculi（ 16 /26 = 61. 5%） and numerous calculi（ 10 /26 = 38. 5%） and（ 22 /26 = 84. 6%） with submandibular gland inflammation. We found that 26 submandibular duct calculi had been incidentally detected in 18 men（ 18 /26 = 69. 2%）and 8 women（ 8 /26 = 30. 8%）. 11（ 11 /44 = 25. 0%） calculi were round and 28（ 28 /44 = 63. 6%） were oval and 5（ 5 /44 =11. 4%） were irregular shape. The size of the lesions was（ 4. 65 ± 0. 86） mm（ 0. 8 ~ 12 mm）. Submandibular duct calculi showed high density traveling along the submandibular duct direction with different size and shape on image CT. We found that submandibular gland increases and uneven density and calculi no enhancement after enhanced scan. Conclusion Combined with clinical manifestations and imaging features can make a clear diagnosis of the submandibular duct calculi.
