To explore the features and diagnostic value of computed tomography (CT) imaging in cases of thymic cysts.
A total of 24 cases of the thymic cysts (confirmed by postoperative pathology) were retrospectively analyzed. The location, morphology, and density of the thymic cysts were summarized, and the changes in CT value of the region of interest (ROI) in the thymic cysts between noncontrast enhanced and enhanced chest scans were compared and classified.
The average long-axis dimension was 17.50 ± 6.00 mm, the CT value range across the 24 cases was 5-81 HU, and the average CT value of the noncontrast enhanced scans was 39.75 ± 20.66 HU. The CT value in the noncontrast enhanced scan was >20 HU in 79% of the sample cases. The CT value in the ROI of the thymic cysts under enhanced scan showed a significant decrease in 15 cases, a significant increase in 5 cases, and an insignificant change in 4 cases.
The CT values of the thymic cysts in the enhanced scans were generally lower than in the noncontrast enhanced scans, which might be a valuable finding for thymic cysts diagnosis.
探讨胸腺囊肿的 CT 影像学特征及其诊断价值。
回顾性分析 24 例经手术病理证实的胸腺囊肿患者的资料，总结胸腺囊肿的位置、形态、密度特点，并比较和分类其平扫与增强扫描时感兴趣区（ROI）CT 值的变化。
24 例患者中，胸腺囊肿长轴平均尺寸为 17.50±6.00mm，CT 值范围为 5-81HU，平扫 CT 值平均为 39.75±20.66HU，79%的病例平扫 CT 值>20HU。15 例患者增强扫描时 ROI 的 CT 值显著下降，5 例显著升高，4 例无明显变化。
胸腺囊肿在增强扫描时 CT 值一般低于平扫，这可能是诊断胸腺囊肿的一个有价值的征象。
