Unusual causes of ovarian vein thrombosis as revealed by CT and sonography.

OBJECTIVE: Ovarian vein thrombosis (OVT) is a pathologic entity classically considered a postpartum complication and only rarely associated with other disease processes. Before modern imaging methods, diagnosis was primarily made clinically or at exploratory surgery. Our objective was to show that with CT and sonographic imaging, OVT can be detected in atypical clinical situations and that the condition may also be occult.
CONCLUSION: Only two of six cases at our institution fit the classic picture of postpartum infection complicated by OVT. The other four cases occurred in conjunction with other pathologic conditions, one of which has not to our knowledge been previously associated with OVT. The diagnosis was not clinically suspected in these four cases. On CT and sonography, OVT was detected incidentally, because clinical symptoms were atypical or absent. Such atypical presentations of OVT pose a clinical dilemma as to appropriate management.
