The value of color Doppler ultrasound in diagnosis and differential diagnosis of ovarian granulosa cell tumor / 中华超声影像学杂志

ABSTRACT

Objective To discuss the value of color Doppler ultrasound in the diagnosis and differential diagnosis of ovarian granulosa cell tumor (OGCT) . Methods Fourteen cases were diagnosed as OGCT by pathology postoperatively had been examined by color Doppler ultrasound check-up before the surgery . In image appearance ,the tumors were divided into cystic mass ,solid mass or mixed cystic-solid mass respectively according to their own pathological features . Additionally ,the blood flowing signal of OGCT was labeled from 0 to 3 grade with Adler standard based on the blood flowing imaging observed by color Doppler flow imaging ( CDFI) . The CDFI results were compared with the pathological diagnosis . Results Ultrasound image appearance of OGCT varied in the 14 cases .Two of them could be characterized as cystic mass ,5 solid mass and 7 mixed cystic-solid mass . The mixed cystic-solid OGCT contained solid mass in multiple cystic degeneration area . There was a significant difference in the diameter among three kinds of OGCT ( P = 0 .0006) . The more visible cystic lesion indicated the longer diameter of OGCT . According to the CDFI ,4 ,5 ,3 and 2 cases were 0 ,1 ,2 ,3 grade respectively in Adler standard . No significant difference was found among the four standards groups ( P =0 .056) . The localization diagnosis accordance rate of the Doppler imaging in OGCT was 71 .4％ (10/14) and the qualitative diagnosis accordance rate was 35 .7％ (5/14) . Conclusions The color Doppler ultrasonography can be the first-line preoperative imaging investigation in the diagnosis and differential diagnosis of OGCT ,as well as in the long-term following after surgery . It can provide more details and evidences for the treatment and prognosis assessment of OGCT .
