 Evaluation of pelvic masses in females with MRA along with HPE correlation. Background and objectives of the study, pelvic mass lesions are most common among women of all age groups but more common among reproductive age. Differential diagnosis of pelvic mass is complex. The main objective of the study is to qualify the diagnostic yield of MRA with HPE correlation, helps to narrow down the differential diagnosis in patients suspected to be suffering from pelvic masses and guide the appropriate management. The purpose of the study is to evaluate the diagnostic accuracy of MRA in patients with suspicion of pelvic masses. In gynecology, pelvic masses are considered among the most common disorders. Lesions of adnexil origin constitute one of the leading cause of female morbidity, a less common cause of mortality and a frequent reason for gynecologic surgery. The benign lesions are usually asymptomatic and most of the times they do not need any treatment and can just be followed up. On the other hand, malignant lesions usually need proper diagnosis and treatment. Pelvic masses pose a challenging situation to a treating gynecologist as well as a radiologist because of the broad and complex differential diagnosis. The most important thing that needs to be determined is categorizing whether the lesion is benign or malignant so that the patient gets appropriate treatment based on pathology. Determining the benign nature of the mass will save the patient from further investigations and unnecessary surgeries. Malignant masses need to be identified as early as possible so that the patient gets early and appropriate treatment. MRA due to its excellent soft tissue contrast, large field of view and multi-planar imaging capabilities, better delineates and characterizes normal pelvic anatomy and pathology. The aims and objectives of the study to describe the MRA features of pelvic masses in determining the benign and malignant nature of uterine survival and adnexal masses. To describe the accuracy of MRA in determination of pelvic masses to correlate the imaging findings in histopathological correlation. A cross-sectional study was conducted on 100 female patients with suspected various pelvic masses taking consent all patients underwent MRA. Results of MRA were correlated with operative or histopathological findings. The study includes patients referred to Department of Radio Diagnosis MNR Medical College in hospital with clinical suspicion of pelvic masses and incidentally detected pelvic masses on ultrasound. Inclusion criteria, patients with clinical suspected cases of cervical uterine adnexal and fallopian tube masses, patients with incidental detection of cervical uterine adnexal and fallopian tube masses on ultrasound. Patients of all age groups will be included in the study. Exclusion criteria, patients with medallic implants, cardiac pacemakers, cochlear implants, patients who are claustrophobic, patients who are unwilling to imaging, patients who do not undergo treatment. MRA of pelvis was done on 1.5 tesla GA-MR signal machine. The following sequences were performed as a part of MRA evaluation. Axial T1, fast recovery, fast pinnacle, sagittal T2, coronal stiff, Axial 2D, fast imaging, employing steady state acquisition, coronal 2D, fast imaging, employing steady state acquisition and decreased rated intake. Contrast agent was used in patients whenever required for better tissue dilution. The results are enumerated below age of the patient below 32 or 22 subjects with a percentage of 22%, 31 to 40, 46 subjects to the percentage of 46%, 41 to 50, 16 subjects or 16 percentage, 51 to 69 subjects of 9%. 61 to 77 subjects, 7% percentage. The table shows the maximum number of cases were in the age group of 31 to 40 years and the minimum number were in the age group of 61 to 70 years. Based on the MRA diagnosis, fibroid shows the 46% percentage. Fibroid with malignant transformation accounts for 1%. Serous Cisterinocarcinoma 3%. Adenoma SS 3%. Carcinoma cervix 6%. Dermoid 3%. Endometrial abscess 1. Endometrial polyp 5%. Hemorrhagic cyst 8%. Hydroxylpines 1%. Mucinocystereinocarcinoma 3%. Pelvic abscess 2%. Light hydroxylpines 3%. Serous Cisterinoma 7%. Serous Papillary Cisterinocarcinoma 1%. Endometrial carcinoma 1%. And a simple 6%. The maximum are the cases of fibroid. On HPE correlation, the MRI diagnosis has correlation with the HPE correlation which showed fibroid as up to 45%. On MRI, 85% of the lesions were diagnosed as benign and 15% of the lesions were diagnosed as malignant. Of the 100, correlation of MRI with HPE, the P value is less than 0.01, malignant 13, benign 1, benign 2, benign 84. The sensitivity is 86.6%. Specificity 98.8%. PPV 92.8%. NPV 97.6%. The accuracy is 97%. MRI showed a overall sensitivity of 86.6%. Specificity of 98.8% diagnostic accuracy of 97% in comparison to histopathological findings. Here is an image of T2 coronal left hydroxylpins and the other one is a serous Cisterinoma. These are the images of turmoid. This is a case of adenomyosis. This is a case of fibroid in sagittal coronal and axial areas. Pelvic masses may vary from benign masses like functional cysts to malignant, ovarian or cervical cancers. Ultrason and CT MRI are currently available imaging modalities used ordinarily to evaluate the pelvic masses. MRI should be used for characterization of ovarian masses when ultrasound results are intermediate or Ethiopian. On MRI, 85% of the lesions were diagnosed as benign, 15% of the lesions were diagnosed as malignant. In comparison to the whole standard test that is a histopathological examination of the specimen, obtained from the lapatomy or laparoscopy of uterine adenomyxin masses, the sensitivity, specificity, accuracy of ultrasonography in diagnosing malignancy in the present study was 73%, 94.1% and 91% respectively. The sensitivity, specificity, accuracy of MRI in diagnosing malignancy in the present study was 86.6%, 98.8% and 97% respectively. For each imaging modality, a cancer was considered to be depicted successfully, true positive. It is up to you to be suspicious for a highly suggestive of malignancy with that modality.
