Abstract Aim of the work To evaluate the role of CT and color Doppler sonography in assessment of adenxal neoplasm and to compare its results with the histopathological findings. Conclusion Helical computed tomography is a valuable, non invasive and safe imaging method for assessment of adenxal mass. CT has been shown to be an effective method in identification of malignant lesion through the morphological criteria of the lesions. Moreover, it can be identify the tumor extension to the surrounding structure (bowel, uterus, pelvic side wall, uterus, and peritoneum) as well as the enlarged lymph nodes. However CT can not replace laparotomy as a staging tool since small peritoneal implants (less than 1cm) can not be accurately identified. Color Doppler imaging facilitates the correct visualization and diagnosis of blood vessels. On the bases of our observations, we believe that the presence of a diastolic notch in benign tumors is a valuable finding. Of valuable importance is the localization of blood vessels within the tumor. Proposed cut off values include 1 for RI and 0.6 for RI while most studies have confirmed the general trend of lower indices in malignant masses, there is increasing evidence that both indices demonstrate considerable overlap between malignant and benign ovarian masses, therefore a low resistance of tumor vessels can not be taken as a criterion for malignancy. For the evaluation of ovarian tumors, PI and RI should be used only in conjunction with other variable. |
