Tsili AC et al. - In a study to evaluate the accuracy of multidetector computed tomography (MDCT) on a 16-row CT scanner in the detection and differentiation of adnexal masses, it was found that MDCT on a 16-row CT scanner proved accurate in the detection and characterization of adnexal masses Methods
102 consecutive women with clinically or sonographically detected adnexal masses were examined
Preoperative CT examination was performed, including scanning of the abdomen during the portal phase, using a detector collimation of 16 × 0.75 mm and a pitch of 1.2
Multiplanar reformatted images were evaluated for presence of an adnexal mass and differentiation between benign and malignant ones, using surgical and pathologic results as standard of reference
CT findings used to diagnose malignancy were: diameter greater than 4 cm, presence of masses bilaterally, cystic-solid mass, necrosis in a solid lesion, cystic lesion with thick, irregular walls or septa and/or with papillary projections
Presence of ascites, peritoneal metastases and lymphadenopathy was used to confirm malignancy
Results
Histopathologic examination demonstrated 143 adnexal mass lesions, 96 of which were benign and 47 malignant
Multidetector CT detected 129 of the 143 adnexal masses, with an overall accuracy for the diagnosis of malignancy of 89.15%
MDCT findings that were more predictive of malignancy were the presence of papillary projections in a cystic lesion, necrosis in solid mass and peritoneal metastases
