Abstract:
Objective To investigate the application value of multi-mode ultrasonography in the diagnosis of non-functioning parathyroid cysts .Methods The features of multi-mode ultrasonography of 32 non-functioning parathyroid cysts were summarized .The ultrasonographic manifestations of 2D-US, CDFI, 3D-US, in 11 pathologically confirmed parathyroid cysts were analyzed and compared , and physicochemical analysis of the fluid aspirated in 11 cysts under ultrasonograph was also performed in the process .Results Ultra-sonography manifestations of 32 parathyroid cysts were as follows: all cysts were located in the lower parathyroid area ( bottom left:18 cases, bottom right:14 cases).With swallowing, the cysts were not dissonant in movement with the thyroid at the same side , and pressed probe revealed that the cysts were separated with the thyroid , with clear periphery , smooth cyst wall and strong sound transmis-sion and without internal echo or floating small point-shape echo.Color Doppler detection revealed that there was no obvious blood flow signal in the cyst wall .Ultrasonography revealed that there was no contrast medium in the nodules , but the cyst wall displayed isoecho-ic.The volume calculated by 3D-US of the 11 parathyroid cysts was 2.12-12.89 ml, with an average volume of(6.24 ±2.99)ml.Ac-tual volume was 2-12 ml, with an average volume of(6.18 ±2.89)ml, and there was no statistical significance in the volume calculat-ed by 3D-US and actual volume, when comparisons were made between them (P>0.05).The cyst fluid was colorless, transparent, thin and clear.Detection results of parathyroid hormone (PTH ) (98-205 pg/ml) were all higher than the upper limit of the serum norm, with an average volume of (123.25 ±32.39) pg/ml.Conclusion Full knowledge of ultrasonic manifestations was beneficial to higher rate of ultrasonographic diagnosis .Quantitative analysis of cyst fluid was a sure diagnostic method with good safety and mini inva -sion, which was worth further clinical extension .
