Absence of flow in ovarian vein by time-of-flight magnetic resonance angiography without evidence of thrombosis.
A case of absent flow in the left ovarian vein was diagnosed on time-of-flight (TOF) magnetic resonance angiography (MRA) while investigating for pelvic vein thrombosis in a 53-year-old female. This appearance should not be misdiagnosed as a sign of ovarian vein occlusion or thrombosis. Magnetic resonance imaging (MRI) is a sensitive noninvasive imaging modality in such a clinical setting. Familiarity with the potential pitfalls of different MRA techniques is essential for correct diagnosis. A review of different MRA techniques in evaluation of pelvic venous thrombosis is presented.
