Abstract:

Ovarian malignant mixed Mullerian tumor (OMMMT) is a rare and highly invasive tumor; most patients are diagnosed at an advanced stage due to its atypical clinical manifestations. To enhance the accuracy diagnosing the disease and provide a basis for clinical treatment strategies, a retrospective analysis of the clinical data and ultrasound images of the patient with OMMMT confirmed by operation and pathology at Guangzhou Red Cross Hospital, Jinan University in September 2020 was conducted. The ultrasound findings showed that a mixed echogenic mass was observed in the pelvic cavity, with a long diameter exceeding the viewing window, a transverse diameter of 161 mm, and an anteroposterior diameter of 111 mm. The mass exhibited an irregular shape and an uneven cystic wall with varying thicknesses around its periphery. The inner wall was not smooth, and the internal echogenicity of the mass was heterogeneous. Additionally, there were echogenic septa of varying thickness, irregular nodular hypoechoic protrusions, and non-echoic regions within the mass. The mass was closely associated with the cervix and there was no evidence of normal uterine or bilateral ovarian echoes during the examination. Color Doppler flow imaging showed strip-like blood flow signals on the periphery and septum of a palpable mass, and abundant blood flow signals within a nipple-like protrusion, with the detection of arterial spectrum signals; the PSV was 12.1 cm/s, and RI=0.59.
