Abstract:
This study aimed to evaluate the accuracy of CT scan in diagnosing pelvic malignancy. Female pelvic malignancy is one of the main leading causes of death among female. Early and accurate diagnosis is mandatory to obtain a good outcome. During the last years, usage of CT in evaluating pelvic malignancies increased dramatically
The study done in RICK center in the period between march 2016 to september 2016. Study population was any female Patients underwent CT abdomen & pelvis for evaluation of pelvic mass and underwent laprotomy with histopathological examination that confirm pelvic malignancy(Ca ovary, Ca endometrium, Ca cervix, Ca urinary bladder, &Ca rectum). Study sample was 70 patients. The data was collected through interviewer filled questionnaire. Data was managed by using the computer data base management and analysis was performed by using the statistical package for social science (SPSS); version 19.
The result showed, The overall accuracy of CT in diagnosing pelvic malignancy was 85.7%. Out of total 70 cases of gynecological cancers ) diagnosed,(44%) were ovarian,(27.1%) cervical, (13%) endometrial, (12.9%) rectal, &(2.9%) Ca urinary bladder. Mixed adenexial tumors made(32.9%) of Ca ovary cases, (66.7%)of patients with Ca endometrium presented with mass lesion, (84%)of patients of Ca cervix presented with a mass in the CT,(87.1%) cases of Ca urinary bladder were diagnosed as normal, &(66.7%) cases with Ca rectum presented with abnormal wall thickening. Squamous cell carcinoma was the commonest histologic type in cervical & urinary bladder cancers, whereas adenocarcinoma was the commonest histological type in the endometrial, ovarian & rectal cancers. Gynecological cancers were most common in age above 40 years (84.3%).
Normal bony pelvis and pelvic lymph nodes were found in the majority of cases. Omental was the commonest mode of distant metastasis, present in (55%) of patients.
Accuracy of CT in diagnosing pelvic masses was differ according to the type of malignancy, being accurate in diagnosing ovarian and cervical, and of low accuracy in diagnosing rectal & urinary bladder cancers.
Frequency of pelvic masses increases with age. The commonest type of pelvic malignancy was Ca ovary.
