Abstract:
Purpose To investigate the diagnostic value of gray-scale ultrasound on ovarian cystic teratoma.Materials and Methods 83 patients with primary diagnosis of ovarian cystic teratoma underwent gray-scale ultrasonography. The ultrasonic images were compared with postoperative pathologic results. Results 91 cases of 83 lesions were detected. The ultrasonic features were categorized into 6 types: cystoid, solid-like, intracystic dough sign, intracystic hair-ball, intracytic fat-fluid level, and intracytic cluttering sign. The diagnose accordance rate for each sign was 81.0%, 77.8%, 96.2%, 100% and 70.0% respectively. The diagnose accordance rate of ultrasonic diagnosis compared with pathologic results was 89.0% (81/91), and misdiagnosed rate and rate of missing diagnosis was 11.0% (10/91). Conclusion The ultrasonic features of ovarian cystic mature terotoma were of importance diagnostic value, whereas differentiation with ovarian chocolate cysts and ovarian mucus-cystic adenoma should be made cautiously.
