OBJECTIVE: To investigate magnetic resonance imaging (MRI) characteristics of ovarian carcinosarcoma and the diagnostic value of MRI.
METHODS: The MRI features of ovarian carcinosarcoma and clinical data of 5 patients with ovarian carcinosarcoma were reviewed. All the lesions were confirmed by surgery and pathological examination.
RESULTS: MRI of ovarian carcinosarcoma in the 5 cases all showed large tumor mass and heterogeneous high-intensity on T2-weighted images and low-intensity on T1-weighted images, with laminar or stripe-like enhancement. Hemorrhage and necrosis were also displayed in some lesions. In two cases, the tumors invaded the greater omentum, sigmoid colon and the body of the uterus, with regional lymph node involvement. Pelvic effusion was observed in all the cases with pelvic hematocele in 1 case.
CONCLUSION: MRI is useful in the detection and staging of ovarian carcinosarcoma.
