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-o f-flight (TOF) magnetic resonance angiography (MRA) while investigatin g for pelvic vein thrombosis in a 53-year-old female. This appearance should not be misdiagnosed as a sign of ovarian vein occlusion or thro mbosis. Magnetic resonance imaging (MRI) is a sensitive noninvasive im aging modality in such a clinical setting. Familiarity with the potent ial pitfalls of different MRA techniques is essential for correct diag nosis. A review of different MRA techniques in evaluation of pelvic ve nous thrombosis is presented.
