鳃裂囊肿的多层螺旋CT诊断价值探讨

目的 分析鳃裂囊肿的多层螺旋CT表现,探讨多层螺旋CT对鳃裂囊肿的诊断价值,以提高术前诊断的准确性。方法 回顾性分析经手术和病理证实的12例鳃裂囊肿患者的临床及CT资料,12例均行CT平扫和增强检查。结果 本组12例中3例为第一鳃裂囊肿,9例第二鳃裂囊肿,本组无第三、四鳃裂囊肿病例。鳃裂囊肿CT表现为囊性低密度影,囊壁薄,囊内密度均匀,边界清晰,周围组织受压移位。结论 多层螺旋CT检查可以清晰显示鳃裂囊肿的部位、大小、形态及其与周围组织结构的关系,易于做出准确诊断。多平面重组图像可以更加全面直观显示病变,为临床治疗特别是术前制定手术方案提供准确信息。

The value of multislice spiral CT in diagnosis of branchial cleft cyst

Objective To analyze the CT findings of branchial cleft cyst and to discuss the diagnostic value of CT to branchial cleft cyst in order to improve the accuracy of preoperative diagnosis. Methods Clinical and CT data of 12 cases of branchial cleft cyst confirmed by operation and pathology were retrospectively analyzed. All the cases underwent plain and enhanced CT examination. Results Of the 12 patients, 3 cases were the first branchial cleft cyst, 9 cases were the second branchia cleft cyst and no third or fourth branchial cleft cyst cases were found. Branchial cleft cyst of CT showed cystic low density, thin cystic wall, the cystic density, clear boundary and the surrounding tissue compression and displacement. Conclusion Multislice spiral CT examination can clearly display the branchial cleft cyst in terms of location, size, shape and the relationship with the surrounding tissue structure, so it is easy to make an accurate diagnosis. Multiplanar reconstruction images can display the lesions more comprehensively and intuitively, which can provide accurate information for clinical therapy, especially in making preoperative scheme.
