 My name is Dr. Ayushika Vaz, JR3 in radio diagnosis. My paper presentation topic is spectrum of MRA findings in female pelvis. In females, majority of our pelvis tumors arises from geniturinary organs with less common site of origin, including connective tissue nerves and lymphovascular structures. Since accurate diagnosis is essential for optimal management, imaging is useful for suggesting the current diagnosis or narrowing the differential possibilities and distinguishing tumors from their mimics. Pelvic ultrasound is often the first imaging modality performed in women with pelvic symptoms. While ultrasound is often useful to detect pelvic masses, it has significant limitations in assessing masses located deep in the pelvis or near gas filled organs. CT also has limited value in pelvis, owing to its inferior soft tissue contrast. MRA is frequently the optimal imaging modality as it offers both multi-planar capabilities and excellent soft tissue contrast. This presentation highlights a diagnostic accuracy of pelvic masses and focuses on MRA features of some common and uncommon masses. It aims and objectives to describe the MRA features of various pelvic masses in determining its benign or malignant nature, to describe the accuracy of MRA in determination of pelvic masses and third its histopathological correlation. Methodology, a cross-sectional study was conducted in the department of radiopagnosis, VKL Valavallika Medical College and Hospital for 50 females with suspected pelvic masses after taking consent. All patients underwent MRA and results of MRA were correlated with histopathological and operative findings. Inclusion criteria, clinically suspected cases of pathologies, incidentally detected cases of pelvic pathology and ultrasound, patient of all age group will be included. Exclusion criteria, contraindication to MRA like metallic implants, cardiac pacemakers, cochlear implants, claustrophobic patient and the third unwilling for imaging. Some interesting cases, MRA findings in female pelvis. So, first case, uterine fibroid with cystic degeneration in 35 weeks pregnant female, history of sewer abdominal pain. So, this is the fetus and this is the anterior ball intramural fibroid with cystic degeneration. Second case, sacral caldoma in 49-year-old female with lower back pain. T2 sagittal MRA, large heterogeneous lesion arising from S1 and S2 vertebral bodies. This mass is also causing compression over urinary bladder and uterus anteriorly. T1 post-contrast showing strong post-contrast enhancement and also seen involvement of the right side of the hip bone. Third case, diffuse adenomyosis with right hematosulfins. Sagittal T2-weighted MRA, there is thickening of junctional zone, forming an ill-defined area of low-signal intensity with pungent at high-intensity myometrial focamps in the anterior wall of uterus. Same patient, there is T1 and T2 hyper-intensity in the cubelike structure on right side that is right hematosulfins. Incidental finding is bilateral avascular necrosis of the hip joint. Fourth case, uterine AV malformation with the large metoma. T1-weighted MRA showing large hypo-intense mass in the uterus with the few fluids. T2-weighted MRA shows a multiple flow-oids with the heterogeneous mass in the uterus. T1 post-contrast image showing the hematoma which is non-enhancing with the multiple flow-oids, multiple vascular channels brossing the mass. Fifth, serous cystidinoma on T1 it is hyper-intense on T2 it is hyper-intense. Vaginal carcinoma on T2 there is a mass involving anterior wall of the vagina. Slightly posterior T2-weighted image showing a large mass also involving posterior wall of vagina. On post-contrast images the mass is strongly enhancing with the lymph nodes. Seventh, right ovarian dernoid cyst. T1 hyper-intense T2 iso-intense more like towards hyper-intense and T1 fat-set image showing a fat saturation. So this is the dernoid cyst. Cervical carcinoma with the gross hydrometra and uterine deposits. So T1-hypo-intense T2-hydrogenous cervical mass causing gross hydrometra with the uterine deposits which is also enhancing. And diffusion-weighted imaging shows a restriction of cervical mass. Results, MRA were performed in 50 email patients who presented with histories, symptoms and signs of pelvic pathologies. The results are depicted below. Table 1 age distribution. Maximum numbers of cases were in the age group of 31 to 70 years and minimum in less than 30 years of age. Table 2 is of diagnosis. Maximum numbers of cases was of cervical carcinoma followed by the fibroids. Cervical cancer was shown to be occurred in 60 to 70 years of age group and fibroid was common in 30 to 50 years of age group. Correlation of MRA with histopathology. So MRA showed an overall sensitivity of 86% and specificity of 98% and diagnostic accuracy of 98% in comparison to the histopathological correlation. Female pelvis is the most mysterious part of human body which presented with many vague symptoms and gives variety of findings. Comprises of benign masses like fibroid, ovarian impulses to malignant masses like carcinoma cervix and sometimes there is bony malignant lesions like pardo as in my case. Although ultrasound is the first training tool for examination of female pelvis but when sonogram is suboptimal the origin of pelvic mass is not established. Or when differentiation between a simple fluid lesion and unguarded type of ovarian tumors required further clarification. MRA will be the second choice for the further evaluation. In this study MRA showed an overall sensitivity of 86% and specificity of 98% and diagnostic accuracy of 98% in comparison to the histopathological findings. So in comparison to the gold standard test that is histopathological examination of specimen MRA can be very much helpful in obtaining the diagnostic and narrowing the differential in pelvic masses.
