- Abstract:
- Objective To investigate the value of computed tomography (CT) in the differential diagnosis of outprojecting uterine
leiomyoma and ovarian sex cord-stromal tumor. Methods The clinical data of patients with outprojecting uterine leiomyoma
(n=43) and patients with ovarian sex cord-stromal tumor (n=36) treated in the First Affiliated Hospital of Chongqing Medical
University from January 2015 to February 2019 were analyzed retrospectively. The plain and enhanced CT images were analyzed,
and the data were transmitted to ADW4.5 workstation for postprocessing, such as multiplanar reconstruction, maximum intensity
projection and volume rendering. The locations of tumors and the ureter, tumor-feeding artery, the relationship between ovarian
veins and tumors, the enhancement degrees and modes of tumors, and the presence or absence of ascites were observed and
recorded. The diagnostic accuracy of CT was analyzed based on pathological results. Results The lesions of outprojecting uterine
leiomyoma were located in front of or inside the ureter, and were mainly supplied by uterine arteries. A large number of branches
within the tumors were evenly distributed. The solid part of the myoma showed moderate or obvious whirlpool-like enhancement,
and normal ovarian tissues could be observed in the ovarian vein, without being complicated with ascites. The lesions of ovarian
sex cord-stromal tumor were located in front of or inside the ureter, and the tumor were mainly supplied by ovarian arteries. A
small number of branches within the tumors were evenly distributed, and ovarian vascular pedicle sign was observed in venous
phase. No or mildly enhancement was observed in the solid part of the tumor. No normal ovarian tissues could be observed in
the ovarian vein, and there were ascites and ovarian vascular pedicle sign. Taking pathological results as the gold standard, the
accuracy of preoperative CT in the diagnosis of outprojecting uterine leiomyoma and ovarian sex cord-stromal tumor was 93.03%
and 80.56%, respectively. Conclusion CT signs combined with clinical manifestations can accurately diagnose outprojecting
uterine leiomyoma and ovarian sex cord-stromal tumor, worthy of clinical promotion.
