Objective:

To investigate the value of ultrasound in the diagnosis and differential diagnosis of thecoma of the ovary.

Methods:

Thirty-six cases with thecoma of the ovary hospitalized from Sep. 2014 to Aug. 2016 were retrospectively analyzed. All patients underwent ultrasonic and pathological examinations. The diagnosis accuracy and results of the two methods were compared.

Results:

Thirty-four cases were detected lesions by ultrasound (detection rate of 94.44%)

2 cases were missed diagnosed (5.56%)

28 cases were diagnosed correctly (diagnosis accuracy of 77.78%)

6 cases were misdiagno

sed (misdiagnosis rate of 16.67%). Twenty-nine cases were diagnosed as solid tumors by ultrasound

accounted for 85.29%. Five cases were diagnosed as cystic-solid tumors

accounted for 14.71%. The morphology detected by operation and pathology diagnosis were almost the same as that by ultrasound.

Conclusion:

The ultrasonographic manifestations of solid thecoma of the ovary are specific: echo mass

clear boundary

no or only a little blood flow signal

which could be easily diagnosed. It is difficult for ultrasound in differentiating cystic-solid thecoma of the ovary from ovarian cyst

teratoma and ovarian cancer. It is suggested that ultrasound has application value in the diagnosis and differential diagnosis of thecoma of the ovary.
