Figure 3.

30-year old woman with endometrioid adenocarcinoma within a pre-existing ovarian endometrioma. Transverse multiplanar reformatted contrast-enhanced MDCT image shows a large, sharply demarcated left pelvic mass. The dimensions of the tumor were 15.8 × 8 × 15.4 cm. Hyperdense components (arrows) were measured with the same values, as on pre-contrast images, therefore the mass was considered as non-enhancing. Based on MDCT findings, the diagnosis of a benign hemorrhagic adnexal mass lesion was made. (Parameters: 16-row CT scanner; mAs: 110; kV: 120; detector collimation: 16 × 0.75 mm; slice thickness: 0.8 mm; reconstruction interval: 0.5 mm; pitch: 1.2; contrast material: 120 ml; flow rate: 3 ml/sec; scan delay: 70 sec).
