What is the most common complication of mature cystic ovarian teratomas?
Ovarian torsion is considered the most common complication of these lesions, occurring in 3-16% of cases. Other less common recognized complications are malignant transformation and cyst rupture.
Large complex right ovarian cystic lesion occupying the rectouterine space with an intralesional fat-fluid interface. No enhancing invasive soft-tissue components are seen on the contrasted study. It contains two large relatively ill-defined rounded lesions of predominantly fat signal intensity with multiple low and high signal-intensity structures, suggestive of calcifications and hair.
This complex cyst exhibits considerable mass effect upon the adjacent structures.
Multiple dilated parametrial venous channels are present, more pronounced on the left side, with associated left ovarian vein dilatation, suggestive of pelvic congestion.
IUCD in situ.
