Introduction:
Ovarian malignant lymphoma is a relatively uncommon neoplasm and rarely reported via diagnostic imaging, especially focusing on diagnostic ultrasound. Our objective was to provide an overview of the ovarian lymphoma imaging features to provide diagnostic direction for imaging doctors.
Presentation Of Cases:
The researchers retrospectively analyzed images of nine patients with ovarian malignant lymphoma who underwent transvaginal ultrasonography (US), CT and MRI, along with the enrolled clinical information.
Clinical Discussion:
These patients were aged 39-62 years, with a median age of 45 years. In the ultrasound diagnosis, the mass was irregular in shape, with solid hypoechoic mass in 6 cases and cystic mixed echoic mass in 3 cases. Contrast-enhanced ultrasound (CE-US) of one patient with ovarian lymphoma before surgery showed that the hypoechoic mass exhibited eccentric heterogeneous enhancement, with an enhancement time significantly earlier than that of the myometrium. In the CT plain scan and MRI T1-weighted imaging (T1WI) diagnosis, the isodensity and equal signal percentage was 55.6 % (5/9) for both.
Conclusion:
These findings suggest that ovarian malignant lymphoma has certain characteristic imaging manifestations, including clear boundaries, regular morphology, hypoechoic, rich blood supply, and normal follicular structure on US, but the final diagnosis still needs to rely on pathological examination.
