- Abstract:
- Abstract: Objective To realize the differential diagnosis of endometrial stromal sarcoma (ESS) and degenerative uterine fibroids using magnetic resonance imaging (MRI) combined with ultrasound. Methods A retrospective analysis of 19 ESS patients and 36 patients with degenerative uterine fibroids was carried out. The characteristics of MRI histogram (T2WI tumor maximum slice histogram) and color Doppler ultrasonography were analyzed, and the sensitivity and specificity of the combined diagnosis were also evaluated. Results and Conclusion The clinical manifestations of ESS patients and patients with degenerative uterine fibroids are similar, but each has its own characteristics. Compared with patients with degenerative uterine fibroids, ESS patients are older and have larger maximum diameter of the tumor, and the proportion of menopausal women in ESS patients is higher. The basic characteristics of tumors can be detected by ultrasound. The proportion of blurred tumor borders in ESS patients is higher, and ESS is mainly dominated by medium-intensity echo, mostly solid, with abundant blood flow and higher proportion of red degeneration. In contrast, the echo of patients with degenerative hysteromyoma is mostly low-intensity, and the tumor is mostly classified into other structures, with sparse blood flow and higher proportion of steatosis. Meanwhile, MRI is used to detect the parameters related to the T2WI tumor maximum slice histogram, and the results revealed that there were differences in the average value, variance, skewness, kurtosis and several different percentiles (P1, P10, P50, P90) between ESS patients and patients with degenerative uterine fibroid, with statistical significance (P<0.05). The histogram (P50) combined with ultrasound has higher sensitivity and specificity, with the optimal effectiveness.
